IKA LR 1000 control system, laboratory reactor, vacuum, 1000 ml, 0025001991
Scale-up and thermodynamic process control In demanding chemical synthesis, pharmaceutical formulation development and cosmetic polymer processing, the precise reproducibility of thermodynamic and rheological parameters is absolutely essential. The IKA LR 1000 control system is a highly integrated, modular reactor platform that physically simulates the fluid dynamic and thermal behaviour of large-scale industrial production plants on a 1,000-millilitre scale. The system consists of a processor-controlled base station with integrated heating, a borosilicate glass reactor suitable for high vacuum, and high-precision sensor technology. The direct thermal coupling of the heating plate to the reactor base enables a substantial energy input, which heats the medium to precisely defined process temperatures of up to 120 °C. This allows complex endothermic reactions to be carried out or high-molecular-weight resins to be melted under strictly controlled laboratory conditions. Rheology and wall-near mixing kinetics The processing of non-Newtonian, structurally viscous fluids requires specialised mechanical energy input. The system is factory-fitted with the IKA LR 1000.10 anchor stirrer. This stirring element, manufactured from AISI 316L stainless steel, induces immense radial and tangential shear stresses in the medium. The integrated PEEK scrapers continuously abrade the inner wall of the reactor vessel. This kinematics mechanically breaks down the highly insulating thermal boundary layer (hotspots) on the heated glass wall and maximises the convective heat transfer coefficient in matrices with a dynamic viscosity of up to 100,000 mPa·s. To ensure the gentle discharge of these viscous gels and pastes, the reactor vessel (LR 1000.3) included in the set features a dead-space-free bottom drain valve at the lowest point of the vessel. Metrological data acquisition and pH integration The key difference from the “basic” version lies in the metrological superiority of the “control” infrastructure. The base station features a multilingual TFT display which not only controls the rotation speed (10 to 150 rpm) and the heating power, but also acts as a central hub for chemical sensor technology. The system allows the direct connection of pH electrodes for in-situ monitoring of acid-base reactions. The temperature at the core of the medium is simultaneously recorded by the supplied PT 100.30 sensor. An integrated weighing algorithm also continuously measures changes in the torque trend of the stirring mechanism, enabling highly precise, indirect real-time analysis of increases in viscosity (for example, during polymerisation processes). Vacuum architecture and digital system integration Control of the reactor atmosphere is essential for the bubble-free degassing of emulsions or for moisture-sensitive reactions. The system is designed for hermetically sealed vacuum operation. Standard-threaded ports (NS 14 and NS 29) in the lid allow for the gas-tight insertion of sensors and the connection of vacuum pumps or inert gas lines. For certified laboratories (GLP/GMP), the “control” system offers seamless digital traceability. The integrated USB and RS-232 interfaces allow the entire reactor to be connected to a PC in a tamper-proof manner. Using the IKA labworldsoft software, complex temperature and speed ramps can be programmed, and all metrological measurement data (temperature, pH value, torque) can be archived with precise time stamps for official QM audits. Technical details Maximum working volume: 1000 ml Max. operating temperature of the product: 120 °C Viscosity limit: 100,000 mPa·s Rotational speed range: 10 – 150 rpm Torque trend measurement: Integrated for rheological monitoring Temperature measurement: Integrated (including PT 100.30 sensor) pH measurement: Connection for external pH electrode provided (BNC) Vacuum compatibility: System is approved for vacuum operation Product discharge: Via a bottom-mounted drain valve (LR 1000.3) Display: High-resolution TFT display for process visualisation Materials (in contact with the medium): Borosilicate glass 3.3, stainless steel 1.4404, PEEK, PTFE, FFPM Interfaces: USB, RS 232 (compatible with IKA labworldsoft) Permissible ambient temperature: 5 – 40 °C Protection class (according to DIN EN 60529): IP 21 Scope of delivery 1 x IKA LR 1000 control base station 1 x IKA LR 1000.3 laboratory reactor vessel (with bottom drain valve) 1 x IKA LR 1000.10 anchor stirrer (with PEEK scrapers) 1 x IKA PT 100.30 temperature probe 1 x sensor cable (for pH and temperature) 1 x USB cable for data logging 1 x Detailed operating instructions Customised requirements & accessories The LR 1000 control system is supplied as a fully functional complete package. However, to upgrade it to a fully automated synthesis unit, we recommend the following process-related additions: To record acid-base titrations, a separate pH electrode with a BNC connector is required. For bubble-free dispersion under high vacuum, you will also require the LR 1000.41 shaft holder in combination with a T 25 digital LR drive. Please contact our procurement service at any time regarding the complex software integration (IKA labworldsoft) and the fluid dynamics configuration of your specific reactor.
IKA LR 1000.61 Probe holder, for LR 1000, 0004664400
Thermodynamic system integration and absolute hermetic sealing In chemical reaction engineering and the control of high-viscosity polymerisation processes, the precise in-situ measurement of the reaction temperature is crucial for process reliability and kinetics. In order to insert a metrological temperature sensor (such as the PT 100.30) directly into the core of the reaction medium, the physical barrier of the reactor must be breached. The IKA LR 1000.61 sensor holder acts as a static bridge element, connecting this sensor system in an absolutely gas-tight manner to the standard-threaded ports of the LR 1000 reactor lid. The geometrically precise seal fits ensure that the vacuum is not compromised during high-speed degassing of viscous matrices. At the same time, the uncontrolled inflow of atmospheric oxygen during moisture-sensitive reactions (under an inert gas atmosphere) is physically and completely prevented. Metrological Z-axis calibration To ensure representative thermodynamic mapping of the reactor, the sensor’s measuring tip must not remain within the thermal boundary layer of the temperature-controlled reactor wall or in a fluid dynamic dead zone. The design of the LR 1000.61 mounting allows for stepless adjustment of the axial immersion depth (Z-axis) of the inserted sensor. The user can position the sensor with millimetre precision within the fluid core, where the mixing kinetics are highest due to the agitators. The mechanical clamping mechanism then permanently secures the sensor’s stainless steel shaft, preventing axial displacement caused by hydrostatic pressure or the suction generated by the agitator. Mechanical vibration damping and structural integrity High-viscosity, structurally viscous media generate massive tangential flow resistance and high-frequency vibrations when large anchor agitators rotate. These hydrodynamic loads transmit lateral bending moments to the long, thin shaft of the temperature sensor. The LR 1000.61 mounting fixture rigidly secures the sensor in place and absorbs these lateral shear forces. This protects the sensitive platinum resistance structure (PT 100) inside the sensor from microscopic cable breaks or mechanical vibrations that could cause it to lose calibration. All components of the mounting that come into contact with the medium are made from highly chemically resistant materials to withstand corrosive solvent vapours at temperatures of up to 120 °C over the long term. Technical details Product type: Probe holder / Mechanical sensor adapter Process engineering function: Gas-tight integration and static fixation Metrological benefit: Stepless adjustment of the axial immersion depth Vibration mechanics: Absorbs lateral hydrodynamic flow forces Compatibility (reactor): Exclusively suitable for IKA LR 1000 lid systems Compatibility (sensor): Designed for slim probes (such as PT 100.30) Vacuum compatibility: Guarantees absolute system hermeticity during evacuation Thermodynamic resistance: Designed for reactor temperatures up to 120 °C Installation: Form-fit mounting in the standard-threaded ports of the reactor lid Scope of supply 1 x IKA LR 1000.61 probe holder (Important note: The temperature probe and the LR 1000 reactor vessel are not included in the scope of delivery!) Custom requirements & accessories The LR 1000.61 holder is a purely mechanical locking component. To enable thermodynamic monitoring within the reactor, the use of the appropriate IKA PT 100.30 temperature probe is essential. This probe is guided precisely through the holder and connected to the IKA LR 1000 base station to control the heating power in real time based on the metrological in-situ data. Please contact our specialist procurement service at any time for a thermodynamically and mechanically fault-free configuration of your reactor sensor system.
IKA LR-2.ST Starvisc 200 Laboratory Reactor, Measuring Stirrer, 0020020603
Anyone developing a chemical reaction on a laboratory scale and later wanting to transfer it to a larger scale needs more than a stirrer display that only reports a trend. The IKA LR-2.ST Starvisc 200 laboratory reactor measures torque and viscosity directly at the STARVISC 200-2.5 control measuring stirrer while the reaction is running, not afterwards on a separate viscometer. This distinguishes it from the four other versions of the LR-2.ST series, which work with EUROSTAR stirrers and a general torque trend display but provide no calibrated measurement. For high-viscosity media up to 100,000 mPas and working volumes of 500 to 2,000 ml, the system therefore delivers reproducible measured values for process development instead of just a rough estimate.The complete stand system is supplied: the LR.SI base component, the HEAD,REACTOR,LR2.10 reactor lid and the STARVISC 200-2.5 control measuring stirrer. The reactor vessel itself is not included in the scope of delivery. The glass vessel is ordered separately to match the required working volume. This applies equally to all five variants of the LR-2.ST series and should be planned for with the first order of a system.True torque and viscosity measurement during the reactionThe STARVISC 200-2.5 control measures torque and the viscosity derived from it in a calibrated way at the stirring shaft, with a maximum value of 200 Ncm. This is exactly what makes the difference from the general torque trend display of the other LR-2.ST variants: there the display shows whether the torque is rising or falling, here there is a reliable measured value that can be documented and taken into an evaluation. For product development in which viscosity profiles during a reaction (for example in polymerisations or when resins cure) decide the process quality, this is the real reason to buy this model within the series. The minimum speed of 6 rpm additionally allows very slow stirring when a reaction tolerates only little shear energy.Temperature range, working volume and vacuum operationThe working volume is between 500 and 2,000 ml. With a dispersing tool, at least 800 ml should be in the vessel so that the shearing action does not run into empty space. The working temperature ranges from -50 to 230 °C, and the telescopic stand has a stroke of 390 mm for different vessel sizes and set-ups. Vacuum operation down to 25 mbar is possible, for example for degassing media or for reactions that are to take place at reduced pressure. The product-contacting parts of the system itself are made of borosilicate glass, FFPM, PTFE and steel 1.4571. The reactor lid has three NS 29/32 openings and two NS 14/23 openings for sensors, additions or a reflux condenser.Reproducibility and documentation of the measured valuesFor process development, besides the measured value itself, it also matters that a stirring experiment can later be repeated identically. Because the STARVISC 200-2.5 control records torque and viscosity continuously, a batch can be evaluated over time and compared with later batches, instead of merely noting a subjective assessment of the stirrer display. When transferring laboratory results to a larger scale, this traceability is often more important than a single measurement, because deviations between two batches only show up in comparison. For laboratories with documented equipment qualification, factory calibration certificates and IQ/OQ documents for the system are also available, see the section on the procurement service. Especially when comparing different recipes or batches, the system thus provides an objective basis on which decisions in the laboratory can be founded, instead of relying on the impression of a single person at the stirrer.Typical applicationsOptimisation and reproduction of chemical reaction, mixing and homogenising processes on a laboratory scaleProduct development requiring documented torque and viscosity measurement during the reaction, for example with polymerisations, resins or adhesivesProcessing of high-viscosity media up to 100,000 mPasReactions under vacuum or reduced pressure, for example for degassingScale-up preparatory work before moving to a larger production scaleSelection guide within the LR-2.ST familyThe LR-2.ST series is available in five versions with the same stand system and reactor lid, but different stirrers.

If a pure trend display is sufficient and higher torque for very viscous media is wanted instead, the LR-2.ST the High-Performer is the more suitable choice. For applications with lower viscosity requirements and a smaller budget, the LR-2.ST the Allrounder, the LR-2.ST the Versatile and the LR-2.ST the Compact Power are available. The STARVISC 200-2.5 control measuring stirrer is also available separately as a replacement or retrofit part if required.Technical detailsWorking volume500 to 2,000 mlWorking volume with dispersing toolat least 800 mlWorking temperature-50 to 230 °CAchievable vacuum25 mbarMax. viscosity100,000 mPasMin. speed6 rpmTelescopic stand stroke390 mmProduct-contacting materialBorosilicate glass, FFPM, PTFE, steel 1.4571Reactor vessel openings3 x NS 29/32, 2 x NS 14/23Max. torque at the stirring shaft200 NcmPermissible ambient temperature range5 to 40 °CPermissible relative humidity80 %Dimensions (W x H x D)670 x 1240 x 580 mmWeight25 kgScope of delivery1 x LR-2.ST stand system1 x LR.SI base and stand component1 x HEAD,REACTOR,LR2.10 reactor lid1 x STARVISC 200-2.5 control torque measuring stirrerThe reactor vessel is not part of the scope of delivery. The glass vessel is ordered separately to match the required working volume, as are accessories such as stirring elements for other applications, temperature probes, a vacuum pump or a circulating thermostat, if these are not yet available.Use and maintenanceThe system weighs 25 kg and belongs on a stable, level work surface with sufficient load capacity. Before each vacuum operation, a brief visual check of the standard ground joint connections at the lid is worthwhile, as a leak otherwise costs vacuum performance. The permissible ambient temperature range is 5 to 40 °C, the permissible relative humidity 80 %. After stirring high-viscosity or sticky media, the measuring stirrer can be detached from the lid for cleaning without dismantling the entire stand system. When changing between media of different viscosity, it makes sense to check the measuring stirrer for residues before the next batch, because dried-on residues can falsify the torque measurement. At the end of its service life, the system belongs, as electrical equipment, in the separate collection of waste electrical and electronic equipment, not in household waste.Individual requirements and procurement serviceFor the LR-2.ST Starvisc 200, IKA offers an extensive accessory range: reactor vessels in different volumes, further stirring elements such as anchor stirrers or baffles, dispersing tools of the T 25 series, pH and temperature probes, vacuum pumps and controllers, and circulating thermostats for active temperature control. Factory calibration certificates and IQ/OQ documentation are also available if required. Through our procurement service, LT Laborhandel supports you in putting together the right reactor vessel and further components for your LR-2.ST system. In making the selection we take into account the planned working volume, type of medium and process temperature, so that vessel and drive match each other.Frequently asked questionsIs a reactor vessel included in the scope of delivery?No. The Starvisc 200 is supplied as a stand system with base component, reactor lid and measuring stirrer. The glass vessel is ordered separately to match the working volume.How does the Starvisc 200 differ from the other LR-2.ST models?In the stirrer.

IKA HABITAT photo (cell) Control Unit for Photobioreactors, LED Lighting Control and PID Control, 0010007553
Anyone cultivating photoautotrophic organisms such as microalgae or cyanobacteria in a bioreactor needs a light source that can be controlled just as precisely as temperature, pH or gas supply. The IKA HABITAT photo (cell) is the control unit that converts a HABITAT-research bioreactor into a photobioreactor via two LED light panels, featuring timer, continuous and programme modes for the lighting, and PID control for temperature, pH and dissolved oxygen.The scope of delivery comprises only the Control Tower with its control panel and the two LED panels. The double-walled glass vessel required for the bioprocess itself, as well as the pH, temperature and other sensors, are not included with this control unit and are selected separately to suit the planned culture volume.Light control for photoautotrophic culturesTwo LED light panels are included in the Scope of delivery and can be controlled via the 10.4-inch touchscreen tablet in timer, continuous or programme mode. Details regarding spectrum, wavelength and light intensity are available on request. The lighting control system itself supports both constant illumination and day-night cycles, as required by many photoautotrophic cultures to maintain a stable growth rhythm. If necessary, the panels can be reordered individually as spare parts without having to replace the entire control unit. For experimental series with different light programmes, a programme can be saved on the tablet and recalled later, rather than having to reset each run individually.Control parameters for stirrer, temperature, pH and pO2The stirrer operates within a speed range of 1 to 2200 rpm, with options including Off, manual operation, profile mode, cascade pO2 control and a chaotic mixing mode. Temperature control is PID-based, with an operating temperature range of 5 to 80 °C and a control accuracy of ±0.2 °C; heating is provided by a 250 W heating jacket. For pH, a measurement range of 0 to 14 is available with a control accuracy of ±0.05 pH; for pO2/DO, a measurement range of 0 to 200 %sat is available with a control accuracy of 0.3 %sat. Optionally, digital and optical sensors for pH, DO, biomass, redox, cell density and exhaust gas analysis can be connected; like the vessel, these are available as separately purchased accessories. The cascade control system links, for example, the stirrer speed to the measured pO2 value, so that mixing is automatically adjusted when the oxygen content falls.Gas supply and dosingFour mass flow controllers regulate nitrogen, oxygen, air and CO2 continuously or via a cascade control system, with a control accuracy of ±2 % fsr and a flow rate of 10 to 2000 cc/min per gas. Four Watson-Marlow peristaltic pumps are fitted for the dosing of acid, base, anti-foaming agent and culture medium; they deliver between 0.3 and 270 ml/min with an accuracy of ±0.3 ml/min and can be reversed in direction of rotation. The control unit connects via Ethernet, USB-B, RS232, Wi-Fi and OPC UA, and also features dedicated interfaces for the single-use reactor, thermostat and external pump.Data integrity and process documentationThe tablet stores process data on an internal memory with a capacity of 32 GB; this is usually sufficient for cultivation runs lasting several weeks without the need to export data in the interim. If there is a power cut during a run, the control unit restarts automatically and the process continues without needing to be restarted manually. According to the manufacturer, those required to document in accordance with FDA CFR Part 11 can optionally meet these data integrity and traceability requirements using the system; details of a separate certificate are available on request. Ethernet, Wi-Fi and the open OPC UA protocol are available for connection to a higher-level process control system when several reactors are to be monitored simultaneously.Typical applicationsCultivation of microalgae and cyanobacteria with defined light controlBatch, fed-batch and perfusion processes in cell cultivationResearch into biofuels and CO2 sequestration with controlled gas supplyProcesses requiring documented PID control of temperature, pH and pO2What else you needTo make the photobioreactor operational, the Control Tower requires a double-walled glass vessel, available in volumes ranging from 0.5 to 10 l. The standard sensor package for pH, liquid level and foam is included with this vessel package, not with the control unit itself. If you also wish to measure biomass, redox, exhaust gas or cell density, you can add the appropriate optical or digital sensors from the range of accessories. As the heating power and the LED panels generate heat during operation, a circulation cooler is usually also required in practice to actively regulate the vessel’s temperature. Through our procurement service, LT Laborhandel puts together the vessel, sensors and control unit to suit the planned culture, ensuring that the end result is a complete, fully functional system.Technical detailsDisplayTablet PC, 10.4-inch, touchscreenStorage capacity32 GBAutomatic restart after a power cutYesInterfacesEthernet, USB-B, RS232, Wi-Fi, OPC UA, single-pass reactor interface, thermostat interface, external pumpStirrer speed range1 to 2200 rpmSpeed deviationfrom 100 rpm ±2 per cent, up to 100 rpm ±5 rpmheating power250 WTemperature controlPID, 5 to 80 °C, control accuracy ±0.2 °CpH control0 to 14 pH, control accuracy ±0.05 pHpO2/DO control0 to 200 %sat, control accuracy 0.3 %satGas supply4 mass flow controllers for N2, O2, air, CO2Peristaltic pumps4 x Watson-Marlow 114DV, 0.3 to 270 ml/minDimensions (W x H x D)224 x 624 x 405 mmWeight14 kgPermissible ambient temperature range5 to 40 °CProtection classIP 20 in accordance with DIN EN 60529Connected load100 to 240 V, 50/60 Hz, power consumption 300 W, max. 1100 WScope of delivery1 x HABITAT photo cell Control Tower (control unit)1 x tablet with operating and control software, 10.4-inch touchscreen2 x LED light panelsA glass vessel, sensors, a stirring tool for the vessel and a recirculating chiller for temperature control are not included in the Scope of delivery and will be selected separately to suit the project.Use and MaintenanceThe control unit is rated to protection class IP 20, which protects it from large foreign objects but not from splashing water; a dry installation location is therefore essential. The permissible ambient temperature range is 5 to 40 °C; at higher temperatures, the permissible relative humidity decreases linearly from 80 per cent to 50 per cent at 40 °C. Following a power cut, the system restarts automatically; there is no need to manually restart any running processes. The data connection via Ethernet, Wi-Fi or OPC UA allows integration with a higher-level process control system when several reactors are to be monitored simultaneously. At the end of its service life, the control unit, as an electrical appliance, must be disposed of via the separate collection scheme for waste electrical and electronic equipment, not in household waste.Individual requirements and procurement serviceThe HABITAT photo (cell) range includes vessel packages in various volumes, replacement LED panels and sensors for biomass, redox, cell density and exhaust gas analysis. IQ/OQ documentation and qualification documents are also available. Through our procurement service, LT Laborhandel supports you in configuring your bespoke photobioreactor setup, from vessel size to the appropriate sensor configuration.Frequently asked questionsIs the reactor vessel included in the Scope of delivery?No. The HABITAT photo (cell) is the control unit with a tablet and two LED panels; the double-walled glass vessel, suitable for the culture volume, must be ordered separately.Are the standard sensors for pH and liquid level included?No, these are part of the vessel package, not the control unit itself.What lighting control functions does the device have?Timer, continuous and programme modes via the two LED panels supplied, controlled via the tablet.Does the process continue automatically after a power cut?Yes, the control unit restarts automatically without the process needing to be restarted manually.Can the control unit be connected to a process control system?Yes, via Ethernet, Wi-Fi or OPC UA; USB-B and RS232 are also available.
IKA LR 1000.1 laboratory reactor vessel, vacuum reactor vessel, 1000 ml, 0003602000
Thermodynamic process control at the demanding laboratory scale In chemical process engineering, pharmaceutical formulation development and cosmetic synthesis, the precise scale-up of reactions is a highly critical physical challenge. The IKA LR 1000.1 laboratory reactor vessel, as a modular core component of the LR 1000 basic and control systems, is designed precisely for this task. With a usable volume of 1000 millilitres, the vessel enables the precise simulation of industrial mixing and dispersion processes. The thermodynamic design of the vessel allows for a continuous maximum operating temperature of the product of up to 120 °C. Thanks to the direct thermal coupling with the base unit’s heating element, thermal energy is transferred absolutely homogeneously into the reaction medium. This prevents localised overheating (hotspots), which could lead to the denaturation of thermolabile active pharmaceutical ingredients (APIs) or to the uncontrolled boiling of solvents. Fluid mechanics for extremely high-viscosity media Conventional beakers or Erlenmeyer flasks immediately reach their physical limits when processing viscous ointments, highly concentrated polymer solutions or resins. The cylindrical LR 1000.1 vessel is fluid-dynamically optimised for processing media with a dynamic viscosity of up to 100,000 mPa·s. When combined with the appropriate IKA anchor stirrers (such as the LR 1000.11) or high-performance T 25 ULTRA-TURRAX dispersers, this vessel generates immense hydrodynamic shear forces. The wall-following agitation prevents viscous product residues from adhering to the vessel walls, guarantees continuous mass transfer and ensures the physical stability of complex, multiphase emulsions and suspensions. Hermetic isolation and absolute vacuum compatibility A key feature for demanding syntheses is complete control over the atmosphere inside the reactor. The LR 1000.1 is designed for highly sealed operation under vacuum. This is an essential process requirement for the bubble-free degassing of viscous gels or for carrying out moisture-sensitive reactions under inert protective gases (such as argon or nitrogen). The solid reactor lid is equipped with standardised ground-joint ports (3 x NS 14 and 1 x NS 29) for this purpose. These precision-ground ports allow for the absolutely gas-tight insertion of PT 100 temperature sensors, pH electrodes, drip funnels for the precise dosing of reactants, or reflux condensers for the condensation of volatile solvents. The vacuum valve (NS 14), which is already integrated into the lid, enables the direct, controlled evacuation of the system. Material integrity for GMP-regulated environments To rule out cross-contamination and ensure complete chemical resistance to aggressive acids, strong alkalis and organic solvents, all components in contact with the process medium are made from materials of the highest industrial grade. The transparent reactor vessel is made from temperature-cycling-resistant borosilicate glass 3.3, which enables continuous visual monitoring of phase transitions or colour changes during the process. The metallic components, such as sensor feed-throughs and screw connections, are made from high-quality AISI 316L stainless steel, whilst PTFE and extremely durable FPM elastomers serve as sealing materials. The entire reactor vessel can be completely dismantled and cleaned thermally or chemically for decontamination in accordance with Good Laboratory Practice (GLP) standards. Technical details Maximum working volume: 1000 ml Max. operating temperature of the product: 120 °C Fluid dynamics design: For viscosities up to 100,000 mPa·s (system-dependent) Vacuum compatibility: Designed for vacuum operation and degassing processes Reactor vessel material: Borosilicate glass 3.3 (highly transparent, chemically resistant) Material (metals in contact with the medium): AISI 316L stainless steel (material no. 1.4404) Seal material: FPM (fluorinated rubber) and PTFE Lid connections (standard ground joints): 3 x NS 14, 1 x NS 29 Vacuum integration: Includes NS 14 vacuum tap for direct evacuation Compatible drive systems: IKA LR 1000 basic base and LR 1000 control base Permissible ambient temperature: 5 – 40 °C Hygiene: Can be completely dismantled for thorough cleaning Scope of supply 1 x IKA LR 1000.1 laboratory reactor vessel (1000 ml, borosilicate glass) 1 x reactor lid with FPM seals 2 x NS 14 glass stoppers (including clamps) 1 x NS 29 glass stopper (including fixing clamp) 1 x NS 14 vacuum tap (Important note: The IKA base unit, sensors and stirring and dispersing tools are not included in the scope of delivery!) Customised requirements & accessories The LR 1000.1 vessel is the reaction vessel itself and must be coupled with the LR 1000 basic base or control base heating unit. For mechanical drive, you will also require the appropriate IKA anchor stirrer (e.g. model LR 1000.11 in stainless steel or LR 1000.10 with PEEK scrapers for media that adhere strongly to the vessel walls). If you wish to use the vessel in conjunction with an ULTRA-TURRAX T 25 for high-shear dispersion, we would be happy to advise you on the appropriate shaft mounting. Please feel free to contact our procurement service, which specialises in process engineering, at any time for a bespoke configuration of your reactor system.
IKA EasySyn 500 Starter synthesis reactor, #0010016813
Small batch sizes with expensive or hard to source starting materials call for a reactor system that does not first have to be assembled from separate parts. The IKA EasySyn 500 Starter (0010016813) is a complete synthesis reactor system for 500 millilitres of reaction volume: stand, double walled reactor vessel and stirrer are matched to each other and ready to use right after setup. As the smallest model in the EasySyn Starter line, this synthesis reactor is a good fit wherever a batch first needs to run reproducibly on a small scale before larger volumes follow. SY 500 D reactor vessel: borosilicate glass with bottom discharge valve The double walled reactor vessel SY 500 D is made of chemically resistant borosilicate glass 3.3 and has a bottom discharge valve with a spring loaded valve spindle that protects against glass breakage when opening and closing. The reactor lid SY 100.1 provides four openings: one NS 29/32 centre joint for the stirrer plus two further NS 29/32 and one NS 14/23 connection, for example for a dropping funnel, reflux condenser or an external temperature probe. Clamp, clamp ring and the FEP coated O-ring are matched to the DN 100 flange connection of the 500 millilitre vessel, the same flange size also used by the larger 1,000 millilitre model in the line. EUROSTAR 60 digital with propeller stirrer R 4011 SY The drive is the overhead stirrer EUROSTAR 60 digital with a brushless DC motor. It covers a speed range of 0/30 to 2,000 rpm and delivers up to 60 Ncm torque at the stirrer shaft, enough for thin to medium viscosity reaction media at the 500 millilitre scale. A built in torque trend display shows viscosity changes during the reaction. The PTFE coated propeller stirrer R 4011 SY (stirrer head diameter 40 millimetres, shaft length 400 millimetres) can be changed tool free via the keyless chuck R 60. The brushless motor (176 W input, 126 W output) runs without carbon brushes and is therefore considered low maintenance. Vacuum operation down to 3 millibar and usable volume The stirrer shaft guide SY guide makes the system suitable for vacuum operation down to 3 millibar, for example to degas solvents or to stir viscous media without bubble formation. The materials used are rated for a temperature range from minus 50 to plus 200 degrees Celsius, the permissible ambient temperature for operation itself is between 5 and 40 degrees Celsius. The vessel can be used from a fill volume of 30 millilitres, with an immersed temperature probe the usable minimum volume rises to 260 millilitres. Ergonomic stand system for everyday lab use The stand is designed for quick replacement of the reactor vessel and its working height can be adjusted to the operator. Clamp, clamp ring and reactor lid follow the same assembly principle across all DN 100 models in the line. Anyone running several EasySyn sizes in parallel benefits from the same handling logic across the whole range. Starter instead of Advanced: a deliberate choice against extra technology Unlike the Advanced version, the EasySyn 500 Starter does without the LT 5.40 draining set and without an RS232/USB interface on the stirrer. For labs that mainly want to stir and control temperature without linking the process to a PC, this leaner and more affordable setup is sufficient. An external circulation thermostat with temperature hoses is needed in any case for actually heating or cooling the double jacket, regardless of the chosen version. 500 or 1,000 millilitres: which size fits The 500 millilitre model and the larger EasySyn 1000 Starter share the stand, reactor lid, DN 100 flange, propeller stirrer R 4011 SY and the EUROSTAR 60 digital stirrer almost entirely, only the reactor vessel itself is sized differently. Anyone working with small, expensive or only limitedly available starting materials, or wanting to secure a method on a small scale first, is better served by the 500 millilitre vessel, where the usable volume starts at just 30 millilitres. If the batch later grows to a litre or more, the 1000 millilitre model reproduces the same setup at a larger scale without having to change the stirrer or the handling logic. Typical fields of application At the 500 millilitre scale, the EasySyn 500 Starter mainly covers early stages of process development: Method development and feasibility trials with small batch sizes ahead of scale-up Syntheses with expensive or only limitedly available starting materials, where a larger vessel would tie up substance unnecessarily Reproducible reactions under vacuum, for example to degas solvents Training and lab courses with a realistic yet compact reactor setup A first step into reactor based synthesis before larger EasySyn sizes follow Technical details System typeComplete reactor system for organic and aqueous syntheses Max. reaction volume500 ml Min. usable volume30 ml Min. usable volume with temperature probe260 ml Reactor vessel materialBorosilicate glass 3.3, double walled, with bottom discharge valve Reactor vessel flange sizeDN 100 Reactor lid openings1 x NS 29/32 centre joint, 2 x NS 29/32, 1 x NS 14/23 StirrerEUROSTAR 60 digital Stirrer speed range0/30 to 2,000 rpm Max. torque at stirrer shaft60 Ncm Motor power (input / output)176 W / 126 W Stirring toolPropeller stirrer R 4011 SY, PTFE coated (stirrer head diam. 40 mm, length 400 mm) Vacuum capabilitydown to 3 mbar (via stirrer shaft guide) Temperature range (material)-50 °C to +200 °C Permissible ambient temperature5 °C to 40 °C Stand dimensions (W x D x H)500 x 580 x 950 mm Scope of delivery 1 x SY stand 1 x reactor vessel SY 500 D (500 ml, borosilicate glass 3.3, double walled, with bottom discharge valve) 1 x SY clamp 100 1 x SY clamp ring 100 1 x SY O-ring 100 (FEP coated) 1 x reactor lid SY 100.1 1 x propeller stirrer R 4011 SY (PTFE coated) 1 x stirrer EUROSTAR 60 digital (with keyless chuck R 60) 1 x stirrer shaft guide SY guide (vacuum capable down to 3 mbar) Not included are temperature hoses for connecting an external circulation thermostat, nor the thermostat itself, both are additionally required for temperature controlled operation of the double jacket.

IKA LR 1000.11 anchor stirrer, stainless steel, for LR 1000, 0004663000
Macroscopic mixing and near-wall kinetics In the process engineering formulation of highly viscous, pasty or structurally viscous media (such as gels, dense emulsions or polymer suspensions), conventional axial agitators reach their physical limits. In viscous fluids, they merely create local flow cavities, whilst the remainder of the sample matrix stagnates against the reactor wall. The IKA LR 1000.11 anchor stirrer is geometrically designed to precisely match the cylindrical dimensions of the LR 1000 laboratory reactor. Thanks to its U-shaped, wall-proximate design, the stirrer engages with the medium throughout the entire reactor volume. The rotation of the anchor primarily induces tangential and radial flow fields. These shear stresses break down the fluid’s viscosity along the shear gradient, forcing the material near the wall into mass transfer and virtually eliminating fluid-mechanical dead zones. Thermodynamic convection in viscous matrices Even without the use of direct physical wall scrapers (as in the LR 1000.10 model), the geometry of the LR 1000.11 massively improves the thermodynamic efficiency of the reactor system. The rotation close to the wall generates microscopic turbulence in the thermal boundary layer between the reactor wall and the medium. This constant physical exchange of molecular layers continuously draws the fluid, heated by the heating block, into the cooler reactor core. This significantly increases the convective heat transfer coefficient (k-value), drastically minimises temperature gradients within the 1000-ml volume and proactively protects thermolabile analytes from local denaturation. Absolute chemical inertness thanks to a single-material design An outstanding analytical advantage of the LR 1000.11 is the complete absence of polymer components or elastomers. The entire stirrer – from the drive shaft to the anchor blades – is manufactured from solid, corrosion-resistant AISI 316L stainless steel (material number 1.4404). This molybdenum-alloyed austenitic steel offers unrivalled chemical inertness. The anchor stirrer can be used without hesitation in highly aggressive media, concentrated organic solvents, strong acids or at extreme pH values, where stirring elements containing PEEK or PTFE components would be chemically attacked or could swell. GLP-compliant sterilisation and hygiene The absence of wear-prone wiper lips or complex mechanical joints makes the LR 1000.11 a highly hygienic piece of equipment. The smooth, electropolished stainless steel surfaces offer no microscopic surfaces for bacterial biofilms or stubborn chemical residues to adhere to. To ensure strict compliance with GLP/GMP hygiene guidelines, the stirring element can be thermally sterilised in an autoclave at 121 °C (or higher) an unlimited number of times, or thoroughly decontaminated in aggressive ultrasonic baths. Technical details Product type: Anchor stirrer (without scraper) Fluid dynamics design: For highly viscous, laminar and paste-like media Design principle: Rotation close to the wall to generate tangential flows Thermodynamic advantage: Promotion of convective heat transfer within the reactor Compatibility: Exclusively for IKA LR 1000 laboratory reactor systems Material: Solid AISI 316L stainless steel (material no. 1.4404) Chemical resistance: Complete resistance to organic solvents and aggressive acids Wear parts: None (no polymers used whatsoever) Max. permissible operating temperature: 120 °C (limited by the reactor system) Hygiene: Fully autoclavable and chemically sterilisable Scope of supply 1 x IKA LR 1000.11 anchor stirrer (stainless steel) (Important note: The IKA LR 1000 reactor vessel and the base station are not included in the scope of delivery!) Customised requirements & accessories The LR 1000.11 anchor stirrer is the mechanical mixing element and must be operated in conjunction with an IKA LR 1000.1 or LR 1000.3 reactor vessel. If you require even more thorough thermodynamic mixing of the boundary layer when working with extremely sticky resins or those prone to scorching, we recommend switching to the LR 1000.10 model with active PEEK scrapers.

IKA LR 1000.64 pH electrode for the LR 1000 system, BNC, 0004663300
Potentiometric in-situ analysis in complex matrices In chemical process control and pharmaceutical synthesis, the pH value is a critical thermodynamic and kinetic control parameter. The traditional method of taking samples for external pH determination distorts the metrological result due to temperature drop and oxidation, and compromises the reactor’s hermetic seal. The IKA LR 1000.64 pH electrode enables continuous, potentiometric in-situ measurement directly within the active process space. At its electrochemical core is an ion-selective glass membrane. As soon as this is immersed in the aqueous or partially aqueous medium, a galvanic interface potential is generated through the exchange of hydrogen ions (protons). The potential difference between this measuring half-cell and an internal reference system (Ag/AgCl) is recorded as a voltage signal and converted into the exact pH value by the connected transmitter using the Nernst equation. Diaphragm mechanics in highly viscous fluids Measurement in highly structurally viscous, pasty or particle-laden media – such as those typically processed in the LR 1000 reactor – poses a major physical challenge for conventional pH probes. Polymers or resins clog the diaphragm, blocking the essential electrical ion exchange between the reference electrolyte and the reaction medium and leading to significant measurement errors (drift). The LR 1000.64 electrode is geometrically and mechanically engineered specifically for these harsh rheological environments. The specific design of the fluid interface minimises the tendency to clog and guarantees a stable, noise-free signal flow even with extremely viscous polymers or emulsions. System integration and thermal compensation To maintain the reaction chamber under vacuum or inert gas during measurement, the electrode is inserted gas-tight into the lid of the LR 1000 reactor vessel via a standard ground joint. The electrical signal is transmitted via a standardised, heavily shielded BNC connector. As the galvanic potential in the Nernst equation is subject to a strict thermodynamic temperature dependence, the pH value must be continuously corrected by calculation. In the IKA LR 1000 control system, the raw signal from the LR 1000.64 electrode is coupled in real time with the in-situ data from the PT 100 temperature sensor to generate an absolutely temperature-compensated (ATC) and metrologically accurate pH output. Seamless GLP data acquisition The combination of the LR 1000.64 electrode and the IKA LR 1000 control system transforms the reactor into a self-contained analytical station. Acid-base titrations or pH-induced phase transitions can be recorded seamlessly. Using the IKA labworldsoft laboratory software, pH curves can be logged in synchronisation with torque and temperature trends in a tamper-proof manner. For certified laboratories subject to strict GLP or GMP guidelines, this is a fundamental prerequisite for successful QM audits. Technical details Product type: Potentiometric pH electrode Measuring principle: Ion-selective glass membrane with reference system Rheological suitability: Optimised for highly viscous, pasty and particulate-laden media Electrical connection: Shielded BNC connector Compatibility: IKA LR 1000 control base station (or external pH metres) Thermodynamic correction: Requires external temperature compensation (ATC) within the system Mechanical integration: Insertion via standard threaded ports in the reactor lid Chemical resistance: High resistance of the glass shaft to solvents Contents 1 x IKA LR 1000.64 pH electrode (incl. BNC cable) (Important note: Standard ground adaptor, reactor vessel and transmitter are not included in the scope of delivery!) Individual requirements & accessories The pH electrode is a sensor only. To convert the millivolt signal into a readable pH value, you must use the IKA LR 1000 control base station (the ‘basic’ version does not include a transmitter) or a separate, high-impedance pH meter. To anchor the electrode in the reactor lid in a vacuum-tight manner, you will also need to obtain suitable standard-threaded sealing adaptors. Please contact our procurement service at any time for metrologically accurate calibration (buffer solutions) and mechanical configuration.
IKA MV 1 solenoid valve for cooling water control, 0020003763
Thermodynamic control loops and exothermic compensation In chemical reaction engineering and the synthesis of high-molecular-weight polymers, absolute control over the reaction temperature is of critical importance. Particularly in the case of exothermic reactions, in which massive amounts of thermal energy are released at the molecular level, the system must cool down immediately to prevent thermodynamic runaway of the reactor. The IKA MV 1 solenoid valve is the fluid-mechanical actuator for this cooling process. Integrated into the cooling water circuit of a laboratory reactor, it acts as an electronic switch for the fluid. If the reaction medium exceeds the programmed setpoint temperature at the temperature sensor, the valve receives an electrical control pulse, opens the flow path and floods the cooling jacket or the system’s internal reflux cooler with temperature-controlled cooling water, thereby immediately maximising convective heat exchange. Electromagnetic Actuation and Fluid Mechanics The physical operating principle of the MV 1 is based on electromagnetic kinematics. When de-energised, a mechanical spring holds the valve piston (armature) in a completely sealed position against the valve seat. This safety principle (normally closed) ensures that, in the event of a power failure, the cooling water circuit is blocked and the laboratory infrastructure is not flooded. When current is applied to the integrated copper coil, it induces a strong magnetic field. The resulting Lorentz force pulls the metallic armature into the coil against the static spring pressure, opening the flow cross-section in fractions of a millisecond. These extremely short switching times allow the higher-level PID controller of the IKA reactor system to regulate the cooling water flow rate at a high frequency in a clocked manner, thereby eliminating thermal oscillations. Pressure stability and prevention of hydrodynamic shocks The switching of incompressible fluids (such as water) in pressurised piping systems inevitably generates massive hydrodynamic pressure peaks (known as pressure surges or water hammer) when the valve closes abruptly. The internal flow architecture of the IKA MV 1 solenoid valve is physically designed to cushion the closing kinetics of the armature in such a way as to minimise these shock waves in the fluid. This reliably protects the sensitive borosilicate glass coolers and the elastomeric hose connections in the reactor assembly from mechanical destruction caused by burst pressure. Metrological system integration The valve does not operate independently, but acts as the precise final element in a complex metrological control loop. It is connected electrically directly to the corresponding relay or control outputs of IKA temperature controllers or reactor base stations (such as the LR 1000 control). This integration transforms the laboratory reactor from a purely heated vessel into a fully automated, bidirectionally temperature-controlled (heating and cooling) thermodynamic system. Technical details Product type: Electromagnetic valve (solenoid valve) Process function: Fluid-mechanical cooling water control Operating principle: Electromagnetic actuation via copper coil Safety design: Normally closed (NC) Thermodynamic benefit: Precise compensation of exothermic reactions Fluid mechanics: Optimised to prevent hydrodynamic pressure surges (water hammer) System integration: Direct control via IKA base stations or temperature controllers Power supply: Supplied via the connected IKA control unit Media compatibility: Designed for aqueous cooling media in piping systems Contents of delivery 1 x IKA MV 1 solenoid valve (Important note: IKA control units, cooling water hoses and reactor infrastructure are not included in the scope of delivery!) Individual requirements & accessories The IKA MV 1 solenoid valve is a purely fluid-mechanical actuator and will not function without a higher-level PID controller. To automate the cooling circuit, the valve must be connected to the appropriate measurement and control technology (e.g. a contact thermometer, a base station or a thermostat with a cooling water relay). Pressure-resistant silicone or EPDM hoses and hose clamps are also required for the mechanical connection to the domestic water supply and the reactor cooler. Please contact our procurement service at any time for the thermodynamically correct design of your cooling systems.
IKA LR-2.ST the Compact Power Laboratory Reactor, 500 to 2000 ml, up to 50,000 mPas, 20013294
High-viscosity media such as gels, pastes, melts or concentrated polymer solutions can hardly be mixed reliably with classic magnetic stirrers. The IKA LR-2.ST the Compact Power laboratory reactor (MPN 20013294) is the most compact and most affordable version of the LR-2.ST reactor platform and processes media with a viscosity of up to 50,000 mPas at a working volume of 500 to 2000 millilitres. This laboratory reactor is therefore suitable for laboratories that need reliable stirring, mixing and homogenising processes at medium to high viscosity without investing straight away in the more powerful configurations of the series. As a modularly configured reactor platform, it is designed for reproducibility, an important criterion when a recipe is later to be produced on a larger scale. Microprocessor-controlled stirrer with torque trend display The LR-2.SI stand system carries the supplied EUROSTAR 60 control laboratory stirrer, which covers a speed range of 8 to 290 revolutions per minute continuously and provides a maximum torque of 60 Ncm at the stirring shaft. The microprocessor-controlled regulation keeps the set speed constant even as the load increases, while the integrated torque trend display makes changes in viscosity in the stirred material visible, for example when a gel forms during a reaction or a solid dissolves. Borosilicate glass reactor vessel for vacuum and temperature changes The 2.0-litre borosilicate glass reactor vessel is designed for a working volume of 500 to 2000 millilitres and operates in a temperature range from room temperature to 230 degrees Celsius at an achievable vacuum of 25 mbar. The LR2.10 reactor lid offers three openings in standard ground joint NS 29/32 and two openings in standard ground joint NS 14/23, through which temperature probes, reflux condensers or further accessories can be introduced gas-tight. Seals made of FFPM (perfluoroelastomer) ensure that even aggressive solvents and the full temperature span of the system have no effect on tightness. Compact format for set-up in the fume hood With dimensions of 460 x 1240 x 430 millimetres, a telescopic foot stroke of 390 millimetres and a weight of around 25 kilograms, the Compact Power can also be set up in fume hoods with limited space. The detachable wireless control unit (WiCo) makes it possible to monitor and control the speed and stirring process from outside the fume hood, so users do not have to stand directly at the device when stirring hazardous or volatile media. Permissible ambient temperatures are 5 to 40 degrees Celsius at a relative humidity of a maximum of 80 per cent. Expandable via the free lid openings The five openings in total in the reactor lid are not reserved only for temperature probes. Depending on the experimental set-up, dispersing tools, reflux condensers, dropping funnels or gas inlet and outlet lines can also be introduced through the standard ground joints. The Compact Power therefore remains usable even when an experiment requires additional sensors or a continuous gas atmosphere in the course of the project, without a completely new reactor set-up being necessary. Entry to the LR-2.ST platform without compromises in process safety The Compact Power shares the stand system, the reactor vessel and the safety equipment with the more powerful LR-2.ST versions the Versatile, the Allrounder and the High-Performer, which are designed for higher viscosities of up to 70,000, 100,000 and 150,000 mPas respectively. If it is foreseeable that future batches will consistently stay within the range up to 50,000 mPas, this basic version saves money compared with the higher torque levels of the series, without having to compromise on glass quality, vacuum resistance or operating concept. The Compact Power can thus be understood as a solid entry-level platform into the world of high-viscosity reactors, which can be scaled up within the same series as requirements grow, without having to learn a new stand system or operating logic. Typical applications The LR-2.ST the Compact Power is used wherever medium-viscosity to viscous media must be stirred or mixed in a controlled way on a laboratory scale: Homogenising creams, gels and emulsions in cosmetics development Stirring and temperature-controlling viscous formulations in pharmaceutical development Chemical syntheses with rising viscosity during the reaction, for example in polymerisations Vacuum-assisted degassing of solutions and dispersions before further processing Scale-up preliminary trials on a laboratory scale before a process is transferred to larger production reactors Formulation development in which recipes with different final viscosities are compared Practical courses and further training in which students or new employees learn how to handle reactor systems Technical details Working volume500 to 2000 ml Min. volume with dispersing tool800 ml Speed range8 to 290 rpm Max. torque at the stirring shaft60 Ncm Max. viscosity50,000 mPas Working temperature rangeRoom temperature to 230 °C Achievable vacuum25 mbar Material (media-contacting parts)Borosilicate glass, stainless steel 1.4571, PTFE, FFPM Reactor lid connections3 x NS 29/32, 2 x NS 14/23 Dimensions (W x H x D)460 x 1240 x 430 mm Telescopic foot stroke390 mm Weightapprox. 25 kg Permissible ambient temperature5 to 40 °C Permissible relative humiditymax. 80 % ControlMicroprocessor-controlled, with torque trend display Remote controlDetachable wireless control unit (WiCo) Scope of delivery 1 x LR-2.SI stand system 1 x LR2.10 reactor lid 1 x Borosilicate glass reactor vessel, 2.0 litres 1 x Anchor stirrer 1 x EUROSTAR 60 control laboratory stirrer 1 x Wireless control unit (WiCo) Individual requirements and procurement service To extend the LR-2.ST the Compact Power into an individual reactor solution, we support you through our procurement service, for example with additional reactor vessels, temperature probes, reflux condensers or dispersing tools for the free openings of the reactor lid.

IKA EasySyn 1000 Starter Synthesis Reactor, Reactor Volume 1000 ml, 0010016815
For many syntheses there is a gap between first hand trials in a round-bottom flask and a real scale-up plant: a millilitre-scale batch says little about behaviour at larger volumes, while a pilot reactor is often oversized for early test series. The IKA EasySyn 1000 Starter (0010016815) closes this gap with a complete reactor system for 1,000 millilitres of reaction volume, made up of stand, double-walled reactor vessel and stirrer, ready for use straight after set-up. Compared with the smaller 500 millilitre model, the additional reaction volume offers more buffer if a batch turns out larger than originally planned when transferred to the reactor, without having to switch straight to the next larger 2 litre model. 1,000 millilitre reactor vessel with the same safety concept as the entire series The double-walled reactor vessel SY 1000 D is made of chemically resistant borosilicate glass 3.3 and has a bottom outlet with a spring-loaded valve spindle, which protects against glass breakage when opening and closing. The reactor lid SY 100.1 offers four openings: an NS 29/32 centre joint for the stirrer as well as two further NS 29/32 and one NS 14/23 connection for accessories such as dropping funnels, reflux condensers or temperature sensors. The flange connection with DN 100 clamp, clamping ring and FEP-coated O-ring is identical to that of the smaller 500 millilitre model, only the vessel itself is larger. Via the bottom outlet, the finished reaction product can be drained directly into a collecting vessel without lifting the vessel to empty it. EUROSTAR 60 digital as a reliable basic drive Mixing is provided by the EUROSTAR 60 digital stirrer with a brushless DC motor. It covers a speed range of 0/30 to 2,000 revolutions per minute and delivers up to 60 Ncm of torque at the stirring shaft, sufficient for most low- to medium-viscosity reaction media on the 1 litre scale. An integrated torque trend display shows changes in viscosity during the reaction. The PTFE-coated pitched-blade stirrer R 4011 SY can be changed without tools via the quick-release chuck R 60. The brushless DC motor (176 watts input, 126 watts output) needs no carbon brushes in continuous operation and is therefore considered low-maintenance. Vacuum, temperature range and usable volume The stirrer shaft guide makes the system suitable for vacuum operation down to 3 mbar, for example for degassing solvents or for bubble-free stirring of viscous media. The materials installed are approved for a temperature range of minus 50 to plus 200 degrees Celsius, and the permissible ambient temperature for continuous operation is between 5 and 40 degrees Celsius. The vessel can be used from 120 millilitres of filling volume, and with the temperature sensor immersed the minimum usable volume rises to 260 millilitres. The stirrer shaft guide (SY guide) seals the passage of the stirring shaft through the reactor lid and is what makes vacuum operation possible in the first place. Ergonomic stand system for everyday laboratory use The stand is designed for quick, uncomplicated exchange of the reactor vessel and its working height can be adjusted to the respective operator. For laboratories that run several EasySyn systems of different sizes in parallel, this is a practical everyday advantage: reactor vessel, clamp, clamping ring and O-ring follow the same design principle on all DN 100 models of the series, so that spare parts and operating procedures are largely the same between the 500 and the 1,000 millilitre model. What the Starter variant deliberately leaves out Unlike the Advanced version, the EasySyn 1000 Starter does without the draining set LT 5.40 and an RS232/USB interface on the stirrer. For laboratories that primarily want to stir and control temperature without connecting the process digitally to a PC, this is not a disadvantage but simply a leaner and less expensive specification. An external circulator including temperature control hoses is in any case additionally required for actual heating or cooling of the double jacket, regardless of the variant chosen. Typical applications With 1,000 millilitres of reaction volume, the EasySyn 1000 Starter sits in the intermediate range between small screening batches and larger sample batches: Process development in the transition between very small batches and larger sample production Reproducible syntheses with defined temperature control and vacuum option Production of larger quantities of an intermediate for downstream analysis Training and practical courses with realistic reactor volumes Cost-efficient entry into reactor-based syntheses without PC connection Technical details System typeComplete reactor system for organic and aqueous syntheses Max. reaction volume1,000 ml Min. usable volume120 ml Min. usable volume with temperature sensor260 ml Reactor vessel materialBorosilicate glass 3.3, double-walled, with bottom outlet Reactor vessel flange sizeDN 100 Reactor lid openings1 x NS 29/32 centre joint, 2 x NS 29/32, 1 x NS 14/23 StirrerEUROSTAR 60 digital Stirrer speed range0/30 to 2,000 rpm Max. torque at the stirring shaft60 Ncm Motor power (input / output)176 W / 126 W Stirring toolPitched-blade stirrer R 4011 SY, PTFE-coated Vacuum suitabilityup to 3 mbar (via stirrer shaft guide) Temperature range (material)-50 °C to +200 °C Permissible ambient temperature5 °C to 40 °C Dimensions of stand system (W x D x H)500 x 580 x 950 mm Scope of delivery 1 x SY stand 1 x reactor vessel SY 1000 D (1,000 ml, borosilicate glass 3.3, with bottom outlet) 1 x SY clamp 100 1 x SY clamping ring 100 1 x SY O-ring 100 (FEP-coated) 1 x reactor lid SY 100.1 1 x pitched-blade stirrer R 4011 SY (PTFE-coated) 1 x EUROSTAR 60 digital stirrer 1 x quick-release chuck R 60 1 x stirrer shaft guide Not included are temperature control hoses for connecting an external circulator, and the circulator itself, both of which are additionally required for temperature-controlled operation of the double jacket.

IKA EasySyn 500 Advanced Synthesis Reactor, Reactor Volume 500 ml, RS232/USB, 0010016809
As soon as syntheses have to be run in a documented and reproducible way across several batches, a simple laboratory set-up is usually no longer sufficient. The IKA EasySyn 500 Advanced (0010016809) is the digitally networked version of the EasySyn reactor system for 500 millilitres of reaction volume: a complete set of reactor vessel, stand and stirrer that can be connected to a PC via RS232 and USB and automated with the IKA laboratory software labworldsoft 6. This makes the system particularly suitable for laboratories that want to log process parameters without gaps or run several synthesis steps one after another in an automated way, for example as part of GLP documentation. Compared with a freely assembled laboratory set-up of individual components, the complete system has the advantage that stand, reactor vessel, lid and stirrer fit together mechanically from the outset. Reactor vessel and safety concept As with the entire EasySyn series, a double-walled reactor vessel made of borosilicate glass 3.3 with a bottom outlet (SY 500 D) forms the core of the system. A spring-loaded valve spindle on the drain valve prevents glass breakage when opening, and the reactor lid provides four openings: an NS 29/32 centre joint for the stirrer as well as two further NS 29/32 and one NS 14/23 connection, for example for dropping funnels, reflux condensers or an external temperature sensor. The clamp, clamping ring and the FEP-coated O-ring are matched to the DN 100 flange connection of the 500 millilitre vessel. Both the borosilicate glass and the FEP-coated O-ring are resistant to a wide range of common solvents and reagents. EUROSTAR 100 control: 100 Ncm with RS232 and USB interface Instead of the simple EUROSTAR 60 digital of the Starter version, the Advanced model uses the EUROSTAR 100 control stirrer. It covers a speed range of 0/30 to 1,300 revolutions per minute and delivers up to 100 Ncm of torque at the stirring shaft for more viscous reaction media. In addition to the RS232 and USB interface for the PC connection, a timer, overload protection and temperature measurement are integrated directly in the stirrer, so that process parameters can also be recorded without separate sensors on the reactor. It drives the same PTFE-coated pitched-blade stirrer (R 4011 SY) as the Starter model. An integrated torque trend display also makes changes in viscosity during the reaction visible, an additional indicator alongside pure temperature measurement. Draining set LT 5.40 for quick vessel changes In contrast to the Starter version, the Advanced variant includes the draining set LT 5.40 in the scope of delivery. Via its own valves, the temperature control liquid can be drained cleanly and without drip losses from the double jacket of the reactor vessel, which noticeably speeds up changing between different reactor vessels or batches, a detail that pays off above all with frequently changing test series. Vacuum operation and temperature range A special stirrer shaft guide allows operation under vacuum down to 3 mbar, useful for degassing or for bubble-free homogenisation of reaction batches. The materials used are designed for temperatures from minus 50 to plus 200 degrees Celsius, and the permissible ambient temperature for operation is 5 to 40 degrees Celsius. The vessel can be used from 30 millilitres of filling volume, and with the temperature sensor immersed the minimum usable volume is 260 millilitres. As with all EasySyn models, the stirrer shaft guide (SY guide) seals the passage of the stirring shaft through the reactor lid and is what makes vacuum operation possible in the first place. Ergonomic stand system with quick vessel change With the Advanced version too, the stand system is ergonomically designed: the working height can be adjusted to the height of the operator, and thanks to the well-thought-out clamping mechanism the reactor vessel itself can be swiftly exchanged for another vessel of the same flange class. In combination with the draining set LT 5.40, a complete batch change, from draining the double jacket to inserting a new reactor vessel, can be carried out considerably faster than with a classic laboratory set-up of individual components. Typical applications The digital connection makes the EasySyn 500 Advanced particularly interesting for applications with increased documentation requirements: GLP-compliant documentation of synthesis parameters via the PC connection and labworldsoft 6 Automated, multi-step reaction control with reproducible process steps Development and optimisation of new synthesis routes on the 500 millilitre scale before scale-up Test series with frequent vessel changes thanks to the draining set LT 5.40 Research and process development requiring gap-free process monitoring Technical details System typeComplete reactor system for organic and aqueous syntheses Max. reaction volume500 ml Min. usable volume30 ml Min. usable volume with temperature sensor260 ml Reactor vessel materialBorosilicate glass 3.3, double-walled, with bottom outlet Reactor vessel flange sizeDN 100 Reactor lid openings1 x NS 29/32 centre joint, 2 x NS 29/32, 1 x NS 14/23 StirrerEUROSTAR 100 control Stirrer speed range0/30 to 1,300 rpm Max. torque at the stirring shaft100 Ncm Additional stirrer functionsTimer, overload protection, temperature measurement integrated InterfacesRS232 and USB Software compatibilitylabworldsoft 6 (available separately) Stirring toolPitched-blade stirrer R 4011 SY, PTFE-coated Vacuum suitabilityup to 3 mbar (via stirrer shaft guide) Temperature range (material)-50 °C to +200 °C Permissible ambient temperature5 °C to 40 °C Dimensions of stand system (W x D x H)500 x 580 x 950 mm Scope of delivery 1 x SY stand 1 x reactor vessel SY 500 D (500 ml, borosilicate glass 3.3, with bottom outlet) 1 x SY clamp 100 1 x SY clamping ring 100 1 x SY O-ring 100 (FEP-coated) 1 x reactor lid SY 100.1 1 x pitched-blade stirrer R 4011 SY (PTFE-coated) 1 x EUROSTAR 100 control stirrer 1 x quick-release chuck R 60 1 x draining set LT 5.40 1 x stirrer shaft guide Not included are temperature control hoses for connecting an external circulator, and the circulator itself, both of which are additionally required for temperature-controlled operation of the double jacket.

IKA LR 1000.41 Shaft holder for T 25 disperser, 0004664300
Kinematic coupling and high-shear integration In the demanding formulation development of nanoparticles, ultra-fine cosmetic emulsions or pharmaceutical suspensions, macroscopic mixing using conventional anchor stirrers is often insufficient from a process engineering perspective. To break down the smallest primary particles or droplets, the localised, intense application of shear forces via rotor-stator systems is absolutely essential. The IKA LR 1000.41 shaft mount is the critical mechanical interface for the positive-lock, secure integration of high-speed dispersing drives – specifically the IKA T 25 digital LR – into the closed LR 1000 laboratory reactor system. This adapter component enables the physical transformation of the reactor from a simple stirred vessel into a thermodynamically controlled high-shear homogeniser. Vibration mechanics and resonance suppression The drive of an IKA T 25 disperser generates enormous kinetic energy at rotational speeds of up to 25,000 revolutions per minute. Even with perfectly balanced dispersing tools, the turbulent flow dynamics in the reactor medium inevitably give rise to high-frequency lateral vibrations. The LR 1000.41 shaft mount is geometrically and statically engineered to precisely absorb these mechanical vibrations. It guarantees the absolute axial alignment (centring) of the dispersing tool within the reactor vessel. This rigid mechanical fixation is of essential importance, as any eccentricity or imbalance would immediately cause mechanical failure of the sensitive FFPM mechanical seals on the vacuum dispersing tools (such as the KD-LR) under hydrostatic pressure. Process flexibility and scale-up The design of the shaft mount allows for a modular and highly reproducible workflow. It enables the process engineer to lower the heavy 800-watt drive motor absolutely vertically and without tension onto the reactor’s standard-threaded lid and lock it in place mechanically. This enables complex multi-step syntheses to be carried out within the same batch: for example, a polymer can first be melted and homogenised under vacuum using an anchor stirrer, and then – following a smooth mechanical changeover to the dispersion drive via the LR 1000.41 mount – be mixed with active ingredients under high-shear conditions. Technical details Product type: Mechanical shaft coupling / motor adapter Kinematic function: Axial alignment and vibration-free mounting of high-performance drives Compatible drive: Designed for the IKA T 25 digital LR disperser Compatible reactor system: IKA LR 1000 basic and LR 1000 control Mechanical property: Absorbs lateral vibrations at speeds of up to 25,000 rpm Compatible tools: Ensures the integrity of S 25 KD-LR vacuum dispersing tools Material: Torsion-resistant industrial metals for maximum mechanical strength Installation: Tool-free attachment to the laboratory reactor lid system Contents of delivery 1 x IKA LR 1000.41 shaft mount (Important note: The IKA LR 1000 reactor vessel, the T 25 dispersing drive and the dispersing tools are not included in the scope of delivery!) Custom requirements & accessories The shaft holder is purely a connecting element. To initiate the physical dispersion process in the reactor, you must have the IKA T 25 digital LR drive (item no. 0020008820) and a vacuum-tight rotor-stator tool from the KD-LR series (e.g. S 25 KD - LR - 25 G). Please contact our procurement service at any time for a statically and kinematically correct configuration of your modular reaction system.
IKA LR 1000.65 pH electrode holder, for LR 1000, 0004663400
Hermetic System Integration and Vacuum Architecture In the chemical process control of complex polymerisations or during the synthesis of high-viscosity emulsions, precise control of the reactor atmosphere is a fundamental thermodynamic prerequisite. The insertion of an analytical pH electrode (such as the IKA LR 1000.64) must under no circumstances compromise the physical isolation of the reaction chamber. The IKA LR 1000.65 pH probe holder acts as a high-precision mechanical adapter to couple the sensor absolutely gas-tight to the standard-threaded lid of the LR 1000 laboratory reactor. The precisely engineered fits and sealing elements of the holder prevent the ingress of atmospheric oxygen during moisture-sensitive reactions carried out under inert gas and ensure that the system vacuum is maintained without interruption during high-speed degassing of viscous media. Mechanical stabilisation against rheological lateral forces In addition to providing a thermodynamic seal, the holder fulfils a vital static protective function. Highly viscous, non-Newtonian fluids, in combination with the rotation of heavy anchor stirrers, generate immense tangential and radial flow vectors. These hydrodynamic shear forces exert massive lateral (sideways) pressure on the fragile glass shaft of the pH electrode. The LR 1000.65 holder rigidly secures the electrode in its axial position and completely absorbs the resulting bending moments and mechanical vibrations. This resonance suppression physically prevents catastrophic glass breakage within the reactor, which would inevitably lead to the physical and chemical destruction of the entire batch. Metrological reproducibility and material integrity For a metrologically error-free in-situ measurement, the ion-selective membrane of the electrode must remain continuously and precisely within the reactor’s designated fluid-dynamic turbulence zone. The holder allows the immersion depth (Z-axis) to be adjusted with millimetre precision and permanently locks the sensor in place against the hydrostatic buoyancy or suction caused by the agitator. To maintain structural integrity even at the maximum temperatures of 120 °C prevailing in the LR 1000 and to withstand corrosive solvent vapours, all components of the mounting that come into contact with the medium are manufactured from highly chemically inert industrial materials. Technical details Product type: Probe holder / Mechanical sensor adapter Process function: Hermetic sealing and static fixation Vibration mechanics: Absorbs lateral bending moments and hydrodynamic shear forces Compatibility (reactor): Exclusively compatible with IKA LR 1000 lid systems Compatibility (sensor): Designed for the IKA LR 1000.64 pH electrode (or 12 mm standard shanks) Vacuum compatibility: Ensures the system remains hermetically sealed during evacuation Thermodynamic resistance: Designed for reactor temperatures up to 120 °C Installation: Form-fit mounting in the standard-threaded ports of the reactor lid Adjustability: Allows for stepless adjustment of the axial immersion depth Scope of supply 1 x IKA LR 1000.65 pH probe holder (Important note: The pH electrode, temperature sensors and the LR 1000 reactor vessel are not included in the scope of delivery!) Custom requirements & accessories The probe holder is a purely mechanical bridge component. For analytical operation, it absolutely requires the corresponding IKA LR 1000.64 pH electrode (item no. 0004663300). Continuous metrological recording of the potentials also requires the IKA LR 1000 control base station, as the basic model does not have the necessary electrical sensor infrastructure. Please contact our procurement service at any time for the thermodynamically and statically correct configuration of the sensor system in the reactor lid.
IKA LR-2.ST the Versatile Laboratory Reactor, 500 to 2000 ml, up to 70,000 mPas, 20013293
Not every batch in the laboratory has the same consistency from start to finish: a solution can be thin at the beginning and become considerably more viscous in the course of a reaction or during evaporation. The IKA LR-2.ST the Versatile laboratory reactor (MPN 20013293) is designed for exactly this range and processes media up to a viscosity of 70,000 mPas at a working volume of 500 to 2000 millilitres. As the middle configuration of the LR-2.ST reactor platform, it offers more torque reserve than the basic version the Compact Power, without yet reaching the price level of the high-viscosity variant the High-Performer. It is therefore aimed above all at laboratories whose batches are not consistently at the limit of the series but vary in viscosity over the duration of the project. EUROSTAR 100 control: more torque reserve for changing viscosities Instead of the EUROSTAR 60 control of the basic version, the Versatile is factory-fitted with the EUROSTAR 100 control laboratory stirrer, which delivers a maximum torque of 100 Ncm at the stirring shaft. The speed range of 8 to 290 revolutions per minute remains identical to the rest of the series, so process parameters from trials with other LR-2.ST versions can be transferred directly. The microprocessor-controlled speed regulation keeps the speed constant even when the viscosity in the reactor rises noticeably. Reactor vessel with vacuum operation and wide temperature window The 2.0-litre borosilicate glass reactor vessel covers a working volume of 500 to 2000 millilitres and operates in a temperature range from room temperature to 230 degrees Celsius at an achievable vacuum of 25 mbar. Temperature probes, reflux condensers or dispersing tools can be connected via the three openings in standard ground joint NS 29/32 and two more in standard ground joint NS 14/23 in the LR2.10 reactor lid. FFPM seals (perfluoroelastomer) withstand both solvent vapours and the full temperature range. Compact stand system with detachable remote control With dimensions of 460 x 1240 x 430 millimetres, a telescopic foot stroke of 390 millimetres and a weight of around 25 kilograms, the Versatile fits the same footprint as the other LR-2.ST versions. The detachable wireless control unit WiCo makes it possible to observe and adjust the speed and stirring process from outside the fume hood, which reduces direct contact at the device, particularly for batches with volatile or toxic media. Permissible ambient temperatures are 5 to 40 degrees Celsius at a maximum of 80 per cent relative humidity, values that can easily be maintained in an air-conditioned laboratory room or under a fume hood. Expandable via five lid openings The LR2.10 reactor lid provides a total of five standard ground joint openings, through which, depending on the experiment, additional sensors, a reflux condenser, a dropping funnel or a gas inlet and outlet line can be connected. The same basic set-up can therefore be used for different test series without having to buy a separate reactor for each configuration, a practical advantage when a laboratory develops several formulations in parallel and sensors are to be moved between batches. Flexibly positioned within the LR-2.ST series Within the four LR-2.ST versions, the Versatile, with a maximum viscosity of 70,000 mPas and 100 Ncm torque, fills the gap between the entry-level variant the Compact Power (50,000 mPas, 60 Ncm) and the more broadly positioned the Allrounder (100,000 mPas, 200 Ncm). For laboratories that regularly work with medium-viscosity to viscous formulations but rarely reach the limit of 100,000 mPas, the Versatile is therefore often closer to the actual requirement than the more powerful versions in the series, which is also reflected in the purchase price compared with the Allrounder and the High-Performer. Typical applications The LR-2.ST the Versatile is particularly suitable for applications with changing or hard-to-predict viscosity during a batch: Stirring reaction batches whose viscosity rises noticeably in the course of the reaction Formulation development in cosmetics and pharmaceuticals with intermediates of varying viscosity Homogenising dispersions and emulsions before filling or further processing Vacuum-assisted degassing of viscous media before a subsequent process step Comparative test series in which several recipes with different final viscosities are tested Transfer of laboratory results towards larger production reactors in scale-up projects Materials research in which additives are stirred step by step into a base matrix and the viscosity rises steadily as a result Quality control in which batches of different consistency are tested under identical stirring conditions Technical details Working volume500 to 2000 ml Speed range8 to 290 rpm Max. torque at the stirring shaft100 Ncm Max. viscosity70,000 mPas Working temperature rangeRoom temperature to 230 °C Achievable vacuum25 mbar Material (media-contacting parts)Borosilicate glass, stainless steel 1.4571, PTFE, FFPM Reactor lid connections3 x NS 29/32, 2 x NS 14/23 Dimensions (W x H x D)460 x 1240 x 430 mm Telescopic foot stroke390 mm Weightapprox. 25 kg Permissible ambient temperature5 to 40 °C Permissible relative humiditymax. 80 % ControlMicroprocessor-controlled, with torque trend display Remote controlDetachable wireless control unit (WiCo) Scope of delivery 1 x LR-2.SI stand system 1 x LR2.10 reactor lid 1 x Borosilicate glass reactor vessel, 2.0 litres 1 x Anchor stirrer 1 x EUROSTAR 100 control laboratory stirrer 1 x Wireless control unit (WiCo) Individual requirements and procurement service For the LR-2.ST the Versatile we support you through our procurement service with additional accessories such as further reactor vessels, temperature probes or dispersing tools for the free lid openings.

IKA EasySyn 5000 Starter Synthesis Reactor, Reactor Volume 5000 ml, 0010016817
At the upper end of the EasySyn series comes the move from pure laboratory scale towards pilot plant: larger batch quantities, longer reaction times, often also the first step towards customer samples or approval batches. The IKA EasySyn 5000 Starter (0010016817) provides a complete reactor system for 5,000 millilitres of reaction volume, made up of stand, double-walled reactor vessel and stirrer, without the additional digital technology of the Advanced variant. As the largest vessel of the EasySyn series, it is suitable for batches where the smaller 500, 1,000 and 2,000 millilitre models would already reach their capacity limit. 5 litre reactor vessel with DN 150 flange The double-walled reactor vessel SY 5000 D made of borosilicate glass 3.3 has, like the smaller EasySyn models, a bottom outlet with a spring-loaded valve spindle that protects against glass breakage when opening and closing, no insignificant detail with a 5 litre vessel with a correspondingly larger fill quantity. The flange connection is sized at DN 150 (SY clamp 150, SY clamping ring 150, FEP-coated SY O-ring 150). The reactor lid SY 150.1 offers four openings: an NS 29/32 centre joint for the stirrer as well as two further NS 29/32 and one NS 14/23 connection for accessories such as reflux condensers or temperature sensors. Via the bottom outlet, the reaction product can be drained directly into a collecting vessel, practical with the large fill quantity of this model. EUROSTAR 60 digital for the largest vessel type of the series The PTFE-coated pitched-blade stirrer R 4013 SY, the stirrer size designed for 5,000 millilitres, is driven by the EUROSTAR 60 digital stirrer. The brushless DC motor covers a speed range of 0/30 to 2,000 revolutions per minute and delivers up to 60 Ncm of torque at the stirring shaft. An integrated torque trend display makes changes in viscosity during the course of the reaction visible. The stirring tool can be changed without tools via the quick-release chuck R 60. The brushless DC motor (176 watts input, 126 watts output) manages without carbon brushes and is therefore considered particularly low-maintenance, an advantage for units that run in continuous operation over longer reaction times. Vacuum, temperature range and usable volume A special stirrer shaft guide makes the system suitable for operation under vacuum down to 3 mbar. The materials used are designed for a temperature range of minus 50 to plus 200 degrees Celsius, and the permissible ambient temperature for operation itself is between 5 and 40 degrees Celsius. The 5,000 millilitre vessel can be used from a filling volume of 1,000 millilitres, and with the temperature sensor immersed the minimum usable volume rises to 1,500 millilitres, considerably more than with the smaller sizes of the EasySyn series. Here too, the stirrer shaft guide (SY guide) takes care of sealing the stirring shaft against the reactor lid. Ergonomic stand system for the largest EasySyn format Even with the largest model of the series, the stand system remains ergonomically designed and its working height can be adjusted to the respective operator, an aspect that comes into play particularly when handling the large and correspondingly heavier 5 litre vessel. The large, correspondingly heavy reactor vessel can be exchanged via the DN 150 clamp without having to dismantle the stand or stirrer. Anyone who runs several EasySyn sizes in parallel in the laboratory also benefits from the fact that the operating logic of clamp, clamping ring and reactor lid is identical across the entire series. What the Starter variant deliberately leaves out The EasySyn 5000 Starter does without the draining set LT 5.40 and an RS232/USB interface on the stirrer, both features of the Advanced version. Anyone who primarily wants to stir, heat or cool in the largest EasySyn format without connecting the process digitally to a PC thus obtains a complete, less expensive system. An external circulator including temperature control hoses is in any case additionally required for actual temperature control of the double jacket, regardless of the variant chosen. Typical applications As the largest model of the Starter series, the EasySyn 5000 Starter covers applications where considerably larger volumes than on the pure screening scale are already needed: Transition from laboratory towards pilot plant or pilot scale Production of larger batches for customer samples, formulation trials or approval documentation Reactions with greater heat exchange requirements thanks to the large double jacket surface Syntheses under vacuum, for example for degassing larger batch quantities Cost-efficient entry to the 5 litre scale without PC connection Technical details System typeComplete reactor system for organic and aqueous syntheses Max. reaction volume5,000 ml Min. usable volume1,000 ml Min. usable volume with temperature sensor1,500 ml Reactor vessel materialBorosilicate glass 3.3, double-walled, with bottom outlet Reactor vessel flange sizeDN 150 Reactor lid openings1 x NS 29/32 centre joint, 2 x NS 29/32, 1 x NS 14/23 StirrerEUROSTAR 60 digital Stirrer speed range0/30 to 2,000 rpm Max. torque at the stirring shaft60 Ncm Motor power (input / output)176 W / 126 W Stirring toolPitched-blade stirrer R 4013 SY, PTFE-coated Vacuum suitabilityup to 3 mbar (via stirrer shaft guide) Temperature range (material)-50 °C to +200 °C Permissible ambient temperature5 °C to 40 °C Dimensions of stand system (W x D x H)500 x 580 x 950 mm Scope of delivery 1 x SY stand 1 x reactor vessel SY 5000 D (5,000 ml, borosilicate glass 3.3, with bottom outlet) 1 x SY clamp 150 1 x SY clamping ring 150 1 x SY O-ring 150 (FEP-coated) 1 x reactor lid SY 150.1 1 x pitched-blade stirrer R 4013 SY (PTFE-coated) 1 x EUROSTAR 60 digital stirrer 1 x quick-release chuck R 60 1 x stirrer shaft guide Not included are temperature control hoses for connecting an external circulator, and the circulator itself, both of which are additionally required for temperature-controlled operation of the double jacket.

IKA Holder MV 1 Mount for measuring vessels, 0020019816
Kinematic fixation and axial alignment In instrumental rheology and the high-precision torque measurement of structurally viscous fluids, the mechanical stability of the measuring vessel is a fundamental metrological requirement. The IKA Holder MV 1 acts as a highly rigid mechanical bridge element for securing specific measuring vessels (MV) within the process setup. When agitators or measuring bodies rotate in highly viscous matrices, enormous torsional forces arise which tend to force the entire vessel into solid-body rotation. The MV 1 holder completely blocks this torque through a rigid form-fit. It guarantees absolute axial alignment (centring) between the drive’s axis of rotation and the geometric centre of the measuring vessel. Any minimal eccentricity would inevitably generate asymmetrical shear gradients in the fluid and severely compromise the reproducibility of the viscosity data. Vibration mechanics and resonance suppression High rotational speeds in viscous or heterogeneous media generate high-frequency lateral vibrations due to uneven flow resistance. The geometric design of the IKA Holder MV 1 is statically engineered precisely to absorb these mechanical vibrations and prevent them from being transmitted to the stand system. This effective resonance suppression physically eliminates noise signals in the sensitive torque transducers of the connected stirrers or rheometers. The signal-to-noise ratio (SNR) of the rheological measurement curves is thereby significantly optimised. Material integrity and ergonomics in everyday laboratory use To withstand high mechanical stresses over the long term and prevent torsion under load, the mount is manufactured from solid, industrial-grade metal alloys. All surfaces are protected against the effects of aggressive solvents, acid vapours and alkalis by means of special surface treatment processes. The design enables the user to clamp and release the vessels quickly and reproducibly, which massively accelerates throughput during serial measurement runs in a regulated quality management environment, without compromising mechanical positioning accuracy. Technical details Product type: Mechanical vessel holder (receptacle) Kinematic function: Fixation against torsional forces and rotation Metrological benefit: Ensures the exact axial alignment of the measuring vessel Vibration control: Absorbs lateral vibrations to stabilise measurement signals Compatibility: IKA MV 1 series measuring vessels Material: Torsion-resistant, chemical-resistant metal alloy Clamping mechanism: Quick and centred clamping without tools Installation: For mounting on standard laboratory stands or IKA system set-ups Contents 1 x IKA Holder MV 1 (holder) (Important note: Stand materials, measuring vessels, and stirring and measuring drives are not included in the scope of delivery!) Individual requirements & accessories The IKA Holder MV 1 is a purely mechanical fixing element. To carry out a reliable rheological measurement, you must use the corresponding measuring vessel and a torque-measuring stirrer or viscometer from IKA. For completely vibration-free installation, we also recommend a solid double-cross-sleeve system and a heavy-duty H-frame stand. Please feel free to contact our specialist procurement service at any time for a structurally sound configuration of your measurement setup.
IKA EasySyn 5000 Advanced Synthesis Reactor, Reactor Volume 5,000 ml, RS232/USB, 0010016812
At the top of the EasySyn series, the IKA EasySyn 5000 Advanced (0010016812) is the largest and best-equipped model, a complete reactor system for a reaction volume of 5,000 millilitres with digital PC connection via RS232 and USB. For the step from laboratory to pilot-plant scale, for example when producing larger customer samples, formulation batches or approval batches, the process can be automated and fully documented with the laboratory software labworldsoft 6. As the largest and best-equipped model of the whole series, the 5000 Advanced is aimed specifically at applications that need both a large reaction volume and complete digital process documentation across several batches. 5-litre reactor vessel with DN 150 flange The double-walled reactor vessel SY 5000 D made of borosilicate glass 3.3 has a bottom outlet with a spring-loaded valve spindle that protects against glass breakage when opening and closing, an important detail with the largest filling volume of the series. The flange connection is matched to the large vessel with DN 150 (SY clamp 150, SY clamping ring 150, FEP-coated SY O-ring 150). The reactor lid SY 150.1 offers four openings: an NS 29/32 centre joint for the stirrer as well as two further NS 29/32 and one NS 14/23 connection, for example for reflux condensers or an additional temperature probe. The borosilicate glass 3.3 and the FEP-coated O-ring are resistant to a wide range of solvents and reagents, even with demanding reaction media at the 5-litre scale. EUROSTAR 100 control for high torques at large volumes Instead of the simple EUROSTAR 60 digital of the starter variant, the Advanced model drives the PTFE-coated pitched-blade stirrer R 4013 SY with the EUROSTAR 100 control overhead stirrer. It covers a speed range from 0/30 to 1,300 revolutions per minute and delivers up to 100 Ncm of torque at the stirrer shaft, important with larger filling volumes and more viscous reaction media. In addition to the RS232 and USB interface, a timer, overload protection and temperature measurement are integrated directly in the overhead stirrer. An integrated torque trend display also makes changes in viscosity visible during the reaction, a useful additional indicator especially with the larger batch sizes in the 5-litre format. Drain set LT 5.40 for changing large reactor vessels The scope of delivery of the Advanced version also includes the drain set LT 5.40. Its own valves allow the temperature control fluid to be drained from the double jacket cleanly and without drip losses, which makes changing a 5-litre reactor vessel much easier, especially when switching between different batches or reaction runs. Without this set, the temperature control fluid would have to be drained manually via the hose connections before each change, which takes a noticeable amount of time with the large filling volume of the 5-litre double jacket. Vacuum, temperature range and usable volume Vacuum operation down to 3 mbar is possible via the stirrer shaft guide. The materials used are approved for a temperature range of minus 50 to plus 200 degrees Celsius, and the permissible ambient temperature for operation itself is between 5 and 40 degrees Celsius. The 5,000 millilitre vessel can be used from a filling volume of 1,000 millilitres, and with the temperature probe immersed the usable minimum volume rises to 1,500 millilitres. The stirrer shaft guide (SY guide) seals the stirrer shaft against the reactor lid and is therefore a prerequisite for vacuum operation down to 3 mbar. Ergonomic stand system with fast vessel change The working height of the stand adapts to the operator and allows the 5-litre reactor vessel to be exchanged quickly via the DN 150 clamp. Together with the drain set LT 5.40 included in the scope of delivery, the double jacket can be emptied completely before the vessel is changed, a noticeable time saving with the largest and therefore also heaviest reactor vessel of the EasySyn series. Typical applications As the largest and best-equipped model of the whole EasySyn series, the EasySyn 5000 Advanced is suitable for applications that require both large volume and digital traceability: Transfer from laboratory to pilot-plant scale with complete documentation Production of larger batches for customer samples, formulation trials or approval documents Automated, multi-step syntheses with reproducible reaction conditions via labworldsoft 6 Reactions with high heat exchange requirements thanks to the large double jacket area and drain set Research and process development with increased documentation requirements in the largest EasySyn format Technical details Type of systemComplete reactor system for organic and aqueous syntheses Reaction volume max.5,000 ml Usable volume min.1,000 ml Usable volume min. with temperature probe1,500 ml Reactor vessel materialBorosilicate glass 3.3, double-walled, with bottom outlet Reactor vessel flange sizeDN 150 Reactor lid openings1 x NS 29/32 centre joint, 2 x NS 29/32, 1 x NS 14/23 Overhead stirrerEUROSTAR 100 control Speed range of overhead stirrer0/30 to 1,300 rpm Max. torque at the stirrer shaft100 Ncm Additional functions of overhead stirrerTimer, overload protection, integrated temperature measurement InterfacesRS232 and USB Software compatibilitylabworldsoft 6 (available separately) Stirring toolPitched-blade stirrer R 4013 SY, PTFE-coated Vacuum capabilityup to 3 mbar (via stirrer shaft guide) Temperature range (material)-50 °C to +200 °C Permissible ambient temperature5 °C to 40 °C Dimensions of stand system (W x D x H)500 x 580 x 950 mm Scope of delivery 1 x SY stand 1 x reactor vessel SY 5000 D (5,000 ml, borosilicate glass 3.3, with bottom outlet) 1 x SY clamp 150 1 x SY clamping ring 150 1 x SY O-ring 150 (FEP-coated) 1 x reactor lid SY 150.1 1 x pitched-blade stirrer R 4013 SY (PTFE-coated) 1 x overhead stirrer EUROSTAR 100 control 1 x quick-release chuck R 60 1 x drain set LT 5.40 1 x stirrer shaft guide Not included are temperature control hoses for connecting an external circulating thermostat, and the thermostat itself.

IKA LR 1000.70 Lid Holder, for the LR 1000 system, 0025003123
Statics and centre of gravity displacement in the workflow In chemical reaction engineering, handling the fully equipped reactor lid during sampling, vessel cleaning or batch changeover poses a significant mechanical risk. The lid of the IKA LR 1000 system acts as a central metrological hub and is heavily laden with instruments: anchor stirrers, flow breakers, pH electrodes and temperature sensors are integrated in a gas-tight manner via standard ground joints. If this assembly is dismantled, the centre of gravity shifts extremely unfavourably due to the stirrers and sensors protruding downwards. The IKA LR 1000.70 lid holder is a structurally highly rigid support stand that compensates for precisely this kinetic instability. The solid base plate and the vertical cantilever arm are physically engineered to absorb the high torque of the asymmetrically loaded lid (including the mounted motorised drive) in a way that prevents tipping and eliminates vibration. Fracture prevention and metrological integrity Placing a loaded reactor lid on standard laboratory worktops inevitably leads to significant mechanical damage. The fragile, ion-selective glass membranes of the pH electrodes or the long stainless-steel shafts of the PT-100 sensors would immediately fracture or undergo plastic deformation (bending moment) under the dead weight of the heavy stainless-steel reactor lid. The LR 1000.70 holder secures the lid at a defined Z-height, ensuring that all instruments protruding into the medium are held completely contact-free and suspended in the air. This static protection maintains the system calibration of the probes and prevents catastrophic sensor failures. Contamination prevention and GLP ergonomics In addition to providing mechanical protection, the lid holder fulfils a vital analytical hygiene function. Stirring elements, to which residues of highly viscous polymers or emulsions may still adhere after synthesis, must not come into physical contact with the working environment. Suspending them freely in the lid holder prevents contamination (carry-over) of the work surface with aggressive or toxic media. At the same time, it ensures that freshly autoclaved instruments do not pick up dust or microbial contaminants from the laboratory bench before the next process step, which is essential for compliance with strict GLP/GMP guidelines. Technical details Product type: Mechanical lid holder / storage rack Static function: Tilt-proof securing of asymmetrically loaded reactor lids Kinematics: Compensation for high bending moments through an optimised centre of gravity Mechanical protection: Prevents glass fractures in pH electrodes and sensor bending Hygiene: Ensures contact-free storage of contaminated or sterile stirring elements Compatibility: Exclusively compatible with IKA LR 1000 lid systems (basic and control) Material: Solid, torsion-resistant and chemical-resistant industrial metal Installation: Self-contained, stand-alone system for the laboratory workstation Contents of delivery 1 x IKA LR 1000.70 lid holder (stand) (Important note: Reactor lids, stir bars, sensors and the laboratory reactor itself are not included in the scope of delivery!) Individual requirements & accessories The LR 1000.70 lid holder is purely an infrastructural addition to the laboratory workstation and functions exclusively in conjunction with an existing IKA LR 1000 reactor system. For high-throughput laboratories that operate several reactor vessels (LR 1000.1 or LR 1000.3) in alternating operation on a base station, this stand is absolutely essential for safely storing the sensor-equipped lid during batch changes. Please feel free to contact our procurement service at any time regarding the ergonomic optimisation of your process systems.
IKA LR 1000.20 Flow Breaker, for LR 1000, 0004663200
Fluid mechanics and the elimination of the vortex effect In chemical reactor technology, the rotation of a centrally positioned agitator – particularly in the case of Newtonian fluids or media with low to medium viscosity – inevitably leads to the formation of a strong tangential flow. The entire fluid begins to rotate as a rigid body with the agitator (solid-body rotation). The physical consequence is the formation of a deep, central vortex (vortex effect), through which atmospheric oxygen is inadvertently drawn into the medium, whilst the actual macroscopic mixing comes to a standstill. The IKA LR 1000.20 flow breaker (baffle) is the essential process engineering component required to counteract this flow phenomenon. Acting as a static obstacle within the reaction chamber, it blocks the laminar tangential flow and forces the photon and mass flows into highly turbulent, axial and radial vectors. This drastically increases the local Reynolds number, maximises the shear gradients and guarantees an absolutely homogeneous, bubble-free phase distribution within the 1000-ml reactor. In-situ thermodynamic measurement in the turbulent core Precise chemical synthesis requires exact thermodynamic monitoring of the reaction temperature directly at the core of the medium, far removed from the thermal boundary layers of the heated reactor wall. The LR 1000.20 flow disruptor fulfils a highly intelligent dual function in this regard: it not only acts as a mechanical disruptor, but is also designed as a hollow protective sleeve. It is designed to accommodate IKA temperature sensors (such as the PT 100.30) directly and centrally. This integration ensures that the temperature is measured precisely within the high-turbulence zone generated by the flow breaker, thereby reducing thermal lags (delays) in the control of the heating output to an absolute minimum. Material integrity and hermetic standard-ground integration To ensure that the atmosphere inside the reactor (vacuum or inert gas) is not compromised, the flow breaker is integrated gas-tight into the lid of the LR 1000 laboratory reactor via a precision-ground standard ground joint. All surfaces of the component that come into contact with the process medium are made of highly corrosion-resistant AISI 316L stainless steel (material number 1.4404). This chemical inertness allows for continuous use in aggressive solvents or acids. The dead-space-free, electropolished, single-material design also prevents the adhesion of microbiological biofilms and enables complete thermal sterilisation in an autoclave in accordance with the strictest GLP guidelines. Technical details Product type: Flow breaker (baffle) with sensor mount Fluid dynamic function: Disruption of laminar tangential flows and vortices Thermodynamic benefit: Drastic increase in mixing kinetics and heat exchange Specific feature: Hollow shaft for the integration of temperature sensors (e.g. PT 100) Compatibility: IKA LR 1000 laboratory reactor systems Material: Solid AISI 316L stainless steel (material no. 1.4404) Installation: Gas-tight integration via standard-threaded ports in the reactor lid Chemical resistance: Complete resistance to organic solvents Vacuum compatibility: Maintains system integrity through precise fits Hygiene: Fully autoclavable and chemically sterilisable Scope of supply 1 x IKA LR 1000.20 flow breaker (stainless steel) (Important note: The IKA LR 1000 reactor vessel, temperature sensors and the base station are not included in the scope of delivery!) Individual requirements & accessories The flow breaker only realises its full potential when coupled with a measuring instrument. To utilise the component’s dual function, you will need the appropriate IKA PT 100.30 temperature probe, which is inserted precisely into the shaft of the breaker. When processing extremely high-viscosity pastes with the anchor agitator (LR 1000.10), the flow breaker is often not physically necessary and may interfere; it is primarily designed for low- to medium-viscosity fluids in combination with propeller or dissolver agitators. Please contact our procurement service for a configuration that is free from fluid-dynamic errors.
IKA EasySyn 2000 Starter Synthesis Reactor, Reactor Volume 2000 ml, 0010016816
From a reaction volume of two litres, the questions of scale-up behaviour, mixing and heat removal move increasingly into the foreground for many syntheses. The IKA EasySyn 2000 Starter (0010016816) provides a complete reactor system that can be set up immediately, combining stand, reactor vessel and stirrer into a ready-to-use unit for 2,000 millilitres of reaction volume, without the additional functions and higher price of the Advanced version. Compared with the smaller 500 and 1,000 millilitre models of the series, the focus with the 2 litre vessel shifts more clearly towards scale-up-relevant questions such as heat removal and mixing of larger volumes. Larger reactor vessel with DN 150 flange The double-walled reactor vessel SY 2000 D made of borosilicate glass 3.3 has, like the smaller EasySyn models, a bottom outlet with a spring-loaded valve spindle against glass breakage. Because of the larger volume, the flange connection here is sized at DN 150 (SY clamp 150, SY clamping ring 150, FEP-coated SY O-ring 150), one size up from the 500 and 1,000 millilitre variants. The reactor lid SY 150.1 offers four openings: an NS 29/32 centre joint for the stirrer as well as two further NS 29/32 and one NS 14/23 connection for additional accessories such as reflux condensers or temperature sensors. The borosilicate glass 3.3 is resistant to most solvents and reagents commonly used in the laboratory, and the finished reaction product can be drained directly into a collecting vessel via the bottom outlet. EUROSTAR 60 digital for larger volumes The PTFE-coated pitched-blade stirrer R 4012 SY, a larger stirrer size specially adapted for the 2 litre vessel compared with the smaller EasySyn models, is driven by the EUROSTAR 60 digital stirrer. The brushless DC motor covers a speed range of 0/30 to 2,000 revolutions per minute and delivers up to 60 Ncm of torque at the stirring shaft. An integrated torque trend display makes changes in viscosity during the reaction visible. The stirring tool can be changed without additional tools via the quick-release chuck R 60. The brushless DC motor (176 watts input, 126 watts output) is designed to be low-maintenance, since, unlike motors with brushes, there are no carbon brushes that wear out and have to be replaced regularly. Vacuum, temperature range and usable volume A special stirrer shaft guide makes the system suitable for operation under vacuum down to 3 mbar. The materials used are designed for a temperature range of minus 50 to plus 200 degrees Celsius, and the permissible ambient temperature for operation itself is between 5 and 40 degrees Celsius. The 2,000 millilitre vessel can be used from a filling volume of 120 millilitres, and with the temperature sensor immersed the minimum usable volume rises to 400 millilitres, considerably more than with the smaller vessel sizes of the series. For pure temperature control, an external circulator is additionally required, which is connected to the reactor vessel via the connections of the double jacket. The stirrer shaft guide (SY guide) takes care of the actual sealing of the stirring shaft against the reactor lid. Ergonomic stand system for larger vessels The stand system also remains ergonomic with the 2 litre model: the working height adapts to the operator, and the reactor vessel can be quickly released and exchanged via the DN 150 clamp. As clamp, clamping ring, O-ring and reactor lid are matched to the same DN 150 flange size on the two larger EasySyn models (2,000 and 5,000 millilitres), spare parts and accessories can be exchanged easily within these two sizes, an advantage for laboratories that keep both sizes in stock. What the Starter variant deliberately leaves out The EasySyn 2000 Starter does without the draining set LT 5.40 and an RS232/USB interface on the stirrer, both features of the Advanced version. For laboratories that primarily want to stir and work under vacuum without logging the process digitally, this is a sensible, cost-efficient specification. An external circulator including temperature control hoses is in any case additionally required to actually heat or cool the double jacket. Typical applications With 2,000 millilitres of reaction volume, the EasySyn 2000 Starter covers the transition between small laboratory scale and first, more meaningful scale-up trials: Scale-up trials between method development and pilot scale Production of larger sample batches for downstream analysis or formulation trials Reactions with increased heat exchange thanks to the larger vessel surface Syntheses under vacuum, for example for degassing larger batch quantities Cost-efficient entry to the 2 litre scale without PC connection Technical details System typeComplete reactor system for organic and aqueous syntheses Max. reaction volume2,000 ml Min. usable volume120 ml Min. usable volume with temperature sensor400 ml Reactor vessel materialBorosilicate glass 3.3, double-walled, with bottom outlet Reactor vessel flange sizeDN 150 Reactor lid openings1 x NS 29/32 centre joint, 2 x NS 29/32, 1 x NS 14/23 StirrerEUROSTAR 60 digital Stirrer speed range0/30 to 2,000 rpm Max. torque at the stirring shaft60 Ncm Motor power (input / output)176 W / 126 W Stirring toolPitched-blade stirrer R 4012 SY, PTFE-coated Vacuum suitabilityup to 3 mbar (via stirrer shaft guide) Temperature range (material)-50 °C to +200 °C Permissible ambient temperature5 °C to 40 °C Dimensions of stand system (W x D x H)500 x 580 x 950 mm Scope of delivery 1 x SY stand 1 x reactor vessel SY 2000 D (2,000 ml, borosilicate glass 3.3, with bottom outlet) 1 x SY clamp 150 1 x SY clamping ring 150 1 x SY O-ring 150 (FEP-coated) 1 x reactor lid SY 150.1 1 x pitched-blade stirrer R 4012 SY (PTFE-coated) 1 x EUROSTAR 60 digital stirrer 1 x quick-release chuck R 60 1 x stirrer shaft guide Not included are temperature control hoses for connecting an external circulator, and the circulator itself, both of which are additionally required for temperature-controlled operation of the double jacket.

IKA LR-2.ST the High-Performer Laboratory Reactor, 500 to 2000 ml, up to 150,000 mPas, 20013291
Tough melts, concentrated polymer solutions or pasty adhesive formulations push many laboratory stirrers to their limits long before the actual recipe is finished. The IKA LR-2.ST the High-Performer laboratory reactor (MPN 20013291) is the most powerful version of the LR-2.ST reactor platform and processes media with a viscosity of up to 150,000 mPas at a working volume of 500 to 2000 millilitres. It is aimed at laboratories that regularly work with extremely high-viscosity media and need a noticeably higher torque reserve than the other three versions of the series offer. As the top configuration of the platform, it shares the reactor vessel, stand system and safety concept with the smaller variants, but differs significantly from them in the drive design. Highest torque level in the LR-2.ST series The High-Performer is fitted with the most powerful laboratory stirrer of the LR-2.ST platform and covers a maximum viscosity of 150,000 mPas, considerably more than the 100,000 mPas of the Allrounder and the 50,000 and 70,000 mPas of the two smaller versions. The speed range of 8 to 290 revolutions per minute remains consistent within the series, so process parameters can still be compared between the four LR-2.ST versions. The microprocessor-controlled regulation keeps the speed stable even when a medium thickens or hardens noticeably in the course of the reaction. Reactor vessel and lid as in the rest of the series The 2.0-litre borosilicate glass reactor vessel is designed for a working volume of 500 to 2000 millilitres and operates in a temperature range from room temperature to 230 degrees Celsius at an achievable vacuum of 25 mbar. The LR2.10 reactor lid offers three openings in standard ground joint NS 29/32 and two more in standard ground joint NS 14/23 for temperature probes, reflux condensers or further accessories. FFPM seals (perfluoroelastomer) ensure reliable sealing is maintained even under the high mechanical loads caused by viscous media and across the entire temperature range of the system. Compact stand system for the strongest drive in the series With dimensions of 460 x 1240 x 430 millimetres, a telescopic foot stroke of 390 millimetres and a weight of around 25 kilograms, the High-Performer takes up no more space than the other LR-2.ST versions despite the stronger drive. The detachable wireless control unit WiCo allows control from outside the fume hood, which provides additional distance from the reactor when stirring particularly viscous or chemically aggressive media. Permissible ambient temperatures are 5 to 40 degrees Celsius at a maximum of 80 per cent relative humidity, values that a normally air-conditioned laboratory room generally meets. Five lid openings for additional sensors The High-Performer also offers a total of five standard ground joint openings via the LR2.10 reactor lid. Particularly with very viscous or hardening media, close temperature monitoring at several points of the reactor is often useful, as is the connection of a gas inlet and outlet line if inert gas is to be introduced during the reaction or solvent vapour is to be removed. The free openings can be fitted flexibly with suitable accessories for this purpose. For the most demanding viscosities in the series Where the Compact Power, the Versatile and the Allrounder reach their limit at 50,000, 70,000 and 100,000 mPas respectively, the High-Performer is designed for media that must still be stirred in a controlled way beyond these values, for example highly concentrated polymer solutions, hot-melt adhesives or pasty formulations shortly before their final consistency. If a project is likely to involve viscosities regularly in the six-figure mPas range, this version saves the later switch from a smaller LR-2.ST variant. Typical applications The LR-2.ST the High-Performer is suitable for stirring and mixing tasks at the upper end of the viscosity spectrum, where other laboratory reactors reach their performance limit: Processing highly concentrated polymer solutions and polymer melts on a laboratory scale Homogenising adhesives, sealants and other pasty formulations Chemical syntheses with a strong rise in viscosity towards the end of the reaction, for example in polycondensations Materials research on high-viscosity formulations shortly before their final consistency Scale-up preliminary trials for production processes in which extremely viscous media already arise in the laboratory Special applications in which smaller LR-2.ST versions are no longer sufficient because of an insufficient torque reserve Research on hot-melt systems and other masses that are solid at room temperature and highly viscous when warm Quality assurance on high-viscosity batches shortly before release, when consistency is to be tested close to production conditions Technical details Working volume500 to 2000 ml Speed range8 to 290 rpm Max. viscosity150,000 mPas Working temperature rangeRoom temperature to 230 °C Achievable vacuum25 mbar Material (media-contacting parts)Borosilicate glass, stainless steel 1.4571, PTFE, FFPM Reactor lid connections3 x NS 29/32, 2 x NS 14/23 Dimensions (W x H x D)460 x 1240 x 430 mm Telescopic foot stroke390 mm Weightapprox. 25 kg Permissible ambient temperature5 to 40 °C Permissible relative humiditymax. 80 % ControlMicroprocessor-controlled, with torque trend display Remote controlDetachable wireless control unit (WiCo) Scope of delivery 1 x LR-2.SI stand system 1 x LR2.10 reactor lid 1 x Borosilicate glass reactor vessel, 2.0 litres 1 x Anchor stirrer 1 x Laboratory stirrer of the highest power level in the LR-2.ST series 1 x Wireless control unit (WiCo) Individual requirements and procurement service For the High-Performer we offer additional accessories through our procurement service, for example further reactor vessels, temperature probes or dispersing tools for the free lid openings.

IKA EasySyn 2000 Advanced Synthesis Reactor, Reactor Volume 2000 ml, RS232/USB, 0010016811
On the 2 litre scale, scale-up work often only becomes truly meaningful, because process engineering effects such as heat removal, mixing time and stirring power show up more clearly than in the smaller vessel sizes of the series, while at the same time the demands on documentation and reproducibility increase. The IKA EasySyn 2000 Advanced (0010016811) combines a complete reactor system for 2,000 millilitres of reaction volume with a digital interface: via RS232 and USB, the stirrer can be connected to a PC and automated with the laboratory software labworldsoft 6, an important criterion when process data have to be recorded without gaps for later evaluation or GLP-compliant documentation. Compared with the Starter version of the same size, the Advanced model is aimed at laboratories that depend on digital traceability of their synthesis parameters. 2,000 millilitre reactor vessel with DN 150 flange The double-walled reactor vessel SY 2000 D is made of borosilicate glass 3.3 and has a bottom outlet with a spring-loaded valve spindle against glass breakage. At DN 150, the flange connection is sized one size larger than on the smaller 500 and 1,000 millilitre models of the series (SY clamp 150, SY clamping ring 150, FEP-coated SY O-ring 150). The reactor lid SY 150.1 offers four openings: an NS 29/32 centre joint for the stirrer as well as two further NS 29/32 and one NS 14/23 connection, for example for reflux condensers or an additional temperature sensor. As with the smaller models of the series, both the borosilicate glass and the FEP-coated O-ring are resistant to a wide range of solvents here as well, an important factor with more aggressive reaction media in scale-up. EUROSTAR 100 control: more torque and digital connection Instead of the EUROSTAR 60 digital of the Starter variant with its 60 Ncm, the Advanced model uses the more powerful EUROSTAR 100 control stirrer to drive the PTFE-coated pitched-blade stirrer R 4012 SY. It covers a speed range of 0/30 to 1,300 revolutions per minute and delivers up to 100 Ncm of torque at the stirring shaft, more reserve for more viscous media in the larger vessel than the EUROSTAR 60 digital of the Starter variant. In addition to the RS232 and USB interface, a timer, overload protection and temperature measurement are integrated directly in the stirrer. An integrated torque trend display also makes changes in viscosity during the reaction visible, a useful additional indicator particularly with larger batch quantities on the 2 litre scale, when the stirring characteristics change in the course of the synthesis. Draining set LT 5.40 for quick batch changes The scope of delivery of the Advanced version also includes the draining set LT 5.40. Via its own valves provided specifically for this purpose, the temperature control liquid can be drained from the double jacket without residue, which noticeably speeds up changing between different reactor vessels or test series on the 2 litre scale, particularly relevant when a reactor has to be reconfigured several times during the working day. Without this set, the temperature control liquid would have to be drained awkwardly via the hose connections of the double jacket before every vessel change. Vacuum, temperature range and usable volume The stirrer shaft guide allows vacuum operation down to 3 mbar. The materials used are approved for temperatures from minus 50 to plus 200 degrees Celsius, and the permissible ambient temperature for operation itself is between 5 and 40 degrees Celsius. The vessel can be used from 120 millilitres of filling volume, and with the temperature sensor immersed the minimum usable volume rises to 400 millilitres. The stirrer shaft guide (SY guide) seals the passage of the stirring shaft through the reactor lid and is thus a prerequisite for vacuum operation. Ergonomic stand system with quick vessel change The working height of the stand adapts to the operator and allows swift exchange of the 2 litre reactor vessel via the DN 150 clamp. Together with the draining set LT 5.40, the double jacket can be emptied without residue before the vessel change, which saves time particularly in scale-up trials with several successive batches per day. Typical applications With digital process documentation, the EasySyn 2000 Advanced is particularly suitable for scale-up work with increased documentation requirements: Scale-up trials with gap-free process documentation via labworldsoft 6 Automated syntheses with several reaction steps and reproducible conditions Production of larger sample batches for analysis, formulation or customer samples Process development with frequent vessel changes thanks to the draining set LT 5.40 Transition from laboratory towards pilot scale with increased documentation requirements Technical details System typeComplete reactor system for organic and aqueous syntheses Max. reaction volume2,000 ml Min. usable volume120 ml Min. usable volume with temperature sensor400 ml Reactor vessel materialBorosilicate glass 3.3, double-walled, with bottom outlet Reactor vessel flange sizeDN 150 Reactor lid openings1 x NS 29/32 centre joint, 2 x NS 29/32, 1 x NS 14/23 StirrerEUROSTAR 100 control Stirrer speed range0/30 to 1,300 rpm Max. torque at the stirring shaft100 Ncm Additional stirrer functionsTimer, overload protection, temperature measurement integrated InterfacesRS232 and USB Software compatibilitylabworldsoft 6 (available separately) Stirring toolPitched-blade stirrer R 4012 SY, PTFE-coated Vacuum suitabilityup to 3 mbar (via stirrer shaft guide) Temperature range (material)-50 °C to +200 °C Permissible ambient temperature5 °C to 40 °C Dimensions of stand system (W x D x H)500 x 580 x 950 mm Scope of delivery 1 x SY stand 1 x reactor vessel SY 2000 D (2,000 ml, borosilicate glass 3.3, with bottom outlet) 1 x SY clamp 150 1 x SY clamping ring 150 1 x SY O-ring 150 (FEP-coated) 1 x reactor lid SY 150.1 1 x pitched-blade stirrer R 4012 SY (PTFE-coated) 1 x EUROSTAR 100 control stirrer 1 x quick-release chuck R 60 1 x draining set LT 5.40 1 x stirrer shaft guide Not included are temperature control hoses for connecting an external circulator, and the circulator itself.

IKA LR 1000.40 Shaft coupling, FFKM, vacuum, for LR 1000, 0025001950
Polymer physics and dynamic system sealing In chemical reaction engineering under extreme environmental conditions – such as with highly aggressive solvents, strong acids or complex syntheses under high vacuum – the physical implementation of rotating tool shafts within the enclosed reaction chamber represents the most critical aspect of system hermeticity. Conventional O-rings made of FKM or EPDM swell due to solvent intercalation, lose their molecular spring force or undergo chemical degradation. The IKA LR 1000.40 shaft housing is therefore fitted with highly specialised dynamic sealing elements made of FFKM (perfluoroelastomer). This high-performance elastomer combines the absolute chemical inertness and thermal stability of PTFE (Teflon) with the viscoelastic, self-sealing memory behaviour of conventional rubbers. This material architecture guarantees that the reactor system remains absolutely vacuum-tight and leak-free, even when processing highly corrosive media and under constant mechanical friction from the rotating shaft. Kinematic alignment and tribology In addition to thermodynamic insulation, the shaft mounting fulfils a critical static function. Highly viscous, structurally viscous media generate enormous radial and tangential flow resistances during the rotation of large agitators. These transmit massive lateral shear forces (bending moments) to the stainless steel shaft. The LR 1000.40 mount acts as a rigid mechanical bridge element. It secures the shaft in perfect alignment (coaxially) along the Z-axis and absorbs the hydrodynamic vibrations. This resonance suppression is tribologically essential: any eccentricity or imbalance in the agitator would otherwise mechanically wear down the sensitive FFKM sealing lips under constant vacuum pressure and immediately destroy the hermetic barrier. Thermodynamic load capacity in the reactor setup The shaft mounting is precisely engineered to match the thermodynamic performance spectrum of the IKA LR 1000 system. The solid stainless steel components and the FFKM seals withstand the standardised maximum temperatures of 120 °C in continuous operation without plastic deformation or loss of seal integrity. Assembly is achieved via a positive-lock fit and is completely gas-tight, directly onto the standardised feed-throughs (standard ground joint) of the reactor lid, which enables safe operation under inert protective gas atmospheres to prevent the oxidation of moisture-sensitive polymerisations. Technical details Product type: Mechanical shaft coupling / stirrer adapter Process function: Dynamic, gas-tight shaft seal Seal material: FFKM (perfluoroelastomer) Mechanical housing: Solid, chemical-resistant stainless steel Chemical resistance: Maximum resistance to highly aggressive solvents, acids and alkalis Vacuum compatibility: Guarantees absolute system hermeticity during high-speed evacuation Tribology: Abrasion-resistant sealing lips for continuous shaft rotation Thermodynamic capacity: Designed for reactor temperatures up to 120 °C Compatibility: Exclusively compatible with IKA LR 1000 lid systems Scope of supply 1 x IKA LR 1000.40 shaft coupling (including FFKM sealing elements) (Important note: Stirring shafts, sensors and the LR 1000 reactor vessel are not included in the scope of delivery!) Custom requirements & accessories The FFKM shaft coupling is a process-related wear and bridging component. Although FFKM exhibits extreme chemical and mechanical resistance, even these dynamic seals are subject to a protracted tribological wear process under constant friction. For facilities operating continuously 24/7 under high vacuum, we recommend metrologically testing the system’s leak-tightness as part of GLP maintenance intervals. Please contact our specialist procurement service at any time for assistance with configuring your reactor setup and sourcing FFKM replacement seals.
