IKA LR 1000 basic System Laboratory Reactor, 1000 ml, up to 100,000 mPas, 20119960

The IKA S 25 KD - LR - 25 G is a specialised dispersing tool designed primarily for use in IKA laboratory reactors (LR series). The distinctive feature of this tool lies in its geometric design: it has an extended shaft (267 mm installation length), which allows for deeper immersion into reactor vessels. This is crucial for ensuring efficient homogenisation even at low liquid levels or with small sample volumes, without the reactor needing to be filled to the brim. KD design for vacuum and cleaning The abbreviation ‘KD’ stands for a special sealing and bearing design that allows operation under vacuum down to 100 mbar. This makes the tool ideal for processes where air ingress must be avoided or which take place under reduced pressure (e.g. degassing during dispersion). At the same time, the KD design enables tool-free disassembly: the rotor can be easily removed, which significantly facilitates cleaning and sterilisation (wet chemical or autoclave) and prevents cross-contamination. Material quality and FDA compliance All parts in contact with the product are manufactured from high-quality materials: stainless steel (AISI 316L), PTFE and FFPM. This combination not only ensures high chemical resistance (pH 2–13) and solvent compatibility, but also meets the strict requirements of the FDA. This makes the tool ideally suited for applications in pharmaceutical and food development, where the highest levels of purity are required.

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.

Rheological challenges and hydrodynamic product discharge In chemical and cosmetic process engineering, the handling of extremely high-viscosity, non-Newtonian fluids – such as structurally viscous polymer gels, pastes or dense emulsions – presents a major physical challenge. Whilst standard reactors usually have to be laboriously dismantled or tilted to remove the end product – a process that leads to high shear stresses and product losses – the IKA LR 1000.3 laboratory reactor vessel features a fully integrated bottom drain valve. This key process engineering component is positioned precisely at the lowest point of the 1000-ml reactor. It enables the continuous or batch discharge of viscous media (up to 100,000 mPa·s) whilst minimising dead volume to an absolute minimum. Direct hydrodynamic emptying preserves the molecular structure of shear-sensitive products and reduces the risk of contamination during transfer to downstream filling systems. Thermodynamic process control and vacuum insulation As the centrepiece of the LR 1000 basic and control systems, the vessel is designed for highly precise thermodynamic reaction control. The thermal energy of the base unit is transferred absolutely homogeneously into the medium via the reactor vessel, which prevents localised overheating (hotspots) and ensures process temperatures of up to 120 °C. Another critical feature of complex syntheses is absolute control of the reactor atmosphere. The LR 1000.3 is fully compatible with high vacuum. Evacuating the reaction chamber is essential for the bubble-free deaeration of gels following high-speed dispersion, or for carrying out moisture-sensitive polymerisations under inert protective gases. The solid reactor lid ensures a hermetic seal against the ambient atmosphere. Metrological connectivity via standardised ports To enable the reactor to be used as a self-contained measurement and control system, the lid is fitted with standardised ground ports (3 x NS 14 and 1 x NS 29). These precision-ground ports allow for the absolutely gas-tight insertion of process-critical sensors (PT 100 temperature sensors, pH electrodes) or process engineering accessories such as drip funnels for precise stoichiometric dosing and reflux condensers for the condensation of volatile solvents. An NS 14 vacuum valve for direct pressure regulation is already integrated into the lid system at the factory. Material integrity in GMP-regulated environments To ensure complete chemical stability against aggressive reactants, strong acids and organic solvents, all components in contact with the process medium are made from materials of the highest industrial quality. The cylindrical reactor body is manufactured from temperature-cycling-resistant, highly transparent borosilicate glass 3.3, which allows for continuous in-situ visual monitoring of phase transitions. The metallic valve components and sensor feed-throughs are made of high-quality AISI 316L stainless steel. Extremely durable FFPM and PTFE elastomers are used as sealing materials. To comply with strict GLP/GMP hygiene guidelines, the bottom drain valve can be completely dismantled for intensive thermal or chemical cleaning. Technical details Maximum working volume: 1000 ml Max. operating temperature of the product: 120 °C Specific feature: Integrated bottom drain valve for highly viscous media Fluid dynamics design: For viscosities up to 100,000 mPa·s Vacuum compatibility: Designed for vacuum operation and degassing Reactor vessel material: Borosilicate glass 3.3 (highly transparent) Material (metals in contact with the medium): AISI 316L stainless steel (material no. 1.4404) Seal material: FFPM and PTFE Lid connections (standard ground joints): 3 x NS 14, 1 x NS 29 Vacuum integration: Includes NS 14 vacuum tap in the lid Compatible drive systems: IKA LR 1000 basic base and LR 1000 control base Hygiene: Valve and vessel can be completely dismantled for decontamination Scope of delivery 1 x IKA LR 1000.3 laboratory reactor vessel (1000 ml, with bottom drain valve) 1 x reactor lid with PTFE/FFPM seals 2 x NS 14 glass stoppers (including clamps) 1 x NS 29 glass stopper (including fixing clamp) 1 x vacuum tap NS 14 Custom requirements & accessories The LR 1000.3 vessel functions purely as a process chamber and must be operated in combination with the IKA LR 1000 basic base or control base heating unit. For mechanical energy input, you will also require a suitable stirring device, such as the LR 1000.11 anchor stirrer. For extremely wall-adhering, viscous gels, we recommend the LR 1000.10 stirrer with PEEK scrapers to maximise heat exchange at the glass wall. Please feel free to contact our specialist procurement service at any time for the thermodynamic and fluid dynamics design of your reactor system.

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.

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.

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.

Anyone wishing to prepare emulsions, suspensions or nanoparticle formulations not in an open beaker but in a closed, temperature-controlled laboratory reactor will need a drive that can be integrated into this system. The IKA T 25 digital LR disperser (0020008820) is designed precisely for this purpose: a dedicated drive unit for high-speed dispersion in laboratory reactors, with a volume range of 1 to 2,000 millilitres (based on water) and a speed range of 600 to 25,000 revolutions per minute. Unlike a benchtop disperser for open beakers, it is designed from the outset for mechanical integration into closed reactor systems and is not intended as a stand-alone, ready-to-use laboratory instrument. Powerful drive with infinitely variable speed control The 800-watt motor (500 watts output power) covers a continuously and electronically adjustable speed range from 600 to 25,000 revolutions per minute, displayed via a digital LED display with a deviation of just 1 per cent from the set target speed. In combination with the appropriate IKA dispersion tools, high shear forces are generated in the narrow shear gap between the rotor and stator, which break down particles and droplets and homogenise liquid phases – the classic operating principle of rotor-stator dispersers. The maximum permissible viscosity of the medium is 5,000 mPa·s, a guideline value that must be taken into account when selecting the dispersing tool and controlling the process. Designed for installation in laboratory reactor systems Unlike free-standing bench-top dispersers, the T 25 digital LR is designed as a drive unit only, which can be mechanically coupled with the special dispersing tools of the KD-LR series. These tools are designed for use in closed laboratory reactors such as the IKA LR 1000 and, thanks to high-quality shaft seals, enable operation under vacuum – which is useful for preventing aerosol and foam formation in media containing surfactants or for processing oxidation-sensitive batches under an inert atmosphere. Neither the dispersing tool nor the reactor itself is included with the T 25 digital LR; both must be purchased separately to suit the specific application. Electronic overload protection and digital display An integrated microprocessor maintains the set speed even when the resistance of the medium changes, for example if the viscosity of a batch increases during the reaction. If the stirring tool becomes suddenly blocked, for example by a jammed particle, an electronic overload protection system switches off the motor and displays an error code; this protects both the motor and the coupled dispersing tool. The unit is designed for continuous operation with a permissible duty cycle of 100 per cent. Compact design for mounting on a reactor stand Measuring 87 x 271 x 106 millimetres and weighing 2.5 kilograms, the T 25 digital LR can be mounted on a reactor stand to save space. The noise level without the dispersing tool fitted is 75 dB(A). The housing is rated to protection class IP 20 and approved for an ambient temperature of 5 to 40 degrees Celsius. It can be connected to either 220 to 240 volts or 100 to 120 volts at 50 or 60 hertz. Selecting the appropriate dispersing tool Which KD-LR tool is suitable in each individual case depends on the reactor volume, the desired immersion depth and the viscosity range of the medium. The tools in this series feature an extended design so that, even in larger reaction vessels, they reach right down to the bottom of the vessel and continue to disperse effectively there, rather than leaving dead volume unused. As the T 25 digital LR is designed as a drive for different reactor sizes and tool variants, the same drive can often continue to be used when process requirements change, whilst only the dispersing tool is replaced. Typical applications As a drive unit for laboratory reactors, the T 25 digital LR is used wherever dispersion processes must take place under controlled, closed conditions: Production of emulsions and creams under air-exclusion conditions in closed reactors Dispersion and homogenisation of suspensions with controlled temperature regulation Scale-up trials between open beaker stirring and pilot reactors Production of finely dispersed systems with limited sample volumes from 1 millilitre Process development in the pharmaceutical and fine chemicals industries with requirements for reproducibility Technical details Product typeDrive unit for dispersion tools in laboratory reactors Volume range (H₂O)1 to 2,000 ml Motor power (input / output)800 W / 500 W Speed range600 to 25,000 rpm, electronically continuously adjustable Speed deviation1 % Speed displayLED display Maximum permissible viscosity of the medium5,000 mPa·s Noise level (without dispersing tool)75 dB(A) Permissible duty cycle100 % (continuous operation) Motor protectionElectronic overload protection with error code display Dimensions (W x H x D)87 x 271 x 106 mm Arm length / Arm diameter160 mm / 13 mm Weight2.5 kg Protection class (to DIN EN 60529)IP 20 Permissible ambient temperature5 to 40 °C Power supply220 to 240 V or 100 to 120 V, 50/60 Hz Contents of delivery 1 x IKA T 25 digital LR drive unit 1 x mains lead for IT equipment 1 x operating instructions Not included are the required dispersing tool from the KD-LR series, the laboratory reactor itself, and a stand for mounting the drive unit. These components must be procured separately to suit the specific application. Customised requirements & procurement service As the T 25 digital LR is designed purely as a drive unit, you will also need a suitable dispersing tool from the KD-LR series and a stand solution to secure the drive in order to operate it on your laboratory reactor. Through our procurement service, we can assist you in selecting the appropriate dispersing tool for your specific application, as well as stand materials, spare parts and accessories for integration into existing reactor systems.

Rheology and fluid mechanics of highly viscous media In chemical reaction engineering and cosmetic formulation, media with high structural viscosity or a paste-like consistency (such as highly concentrated polymer solutions or dense emulsions) tend to form laminar flow profiles. Conventional propeller or turbine agitators fail in these systems, as they only circulate the medium locally at the centre, whilst the fluid near the walls stagnates. The IKA LR 1000.10 anchor stirrer solves this rheological problem through its reactor-specific geometry. The solid stainless-steel anchors rotate with a minimal clearance along the cylindrical inner wall of the LR 1000 laboratory reactor. This wall-adjacent kinetics induces immense radial and tangential shear stresses in the medium, which locally reduce the viscosity in the shear gradient and homogenise the entire 1000-ml reactor contents in a circular pattern, thereby physically eliminating fluid dynamic dead zones. Thermodynamic optimisation using PEEK scrapers The fundamental problem with temperature control of highly viscous fluids in heated reactors is the formation of a highly insulating thermal boundary layer on the reactor wall. Without constant mechanical renewal of this layer, drastic temperature gradients, localised overheating (hotspots) and, in the worst case, irreversible thermal denaturation (burning) of the product near the wall occur. The LR 1000.10 is equipped with flexible scraper blades made of PEEK (polyetheretherketone) to resolve this thermodynamic bottleneck. During operation, these high-temperature-resistant polymer lips continuously scrape along the borosilicate glass wall of the reactor. They mechanically scrape away the static, heated fluid and force it to mix with the cooler reactor core. This process maximises the system’s convective heat transfer coefficient (k-value) and guarantees an absolutely homogeneous temperature distribution throughout the entire sample matrix. Material integrity and chemical resistance To ensure absolute analytical purity in GLP- and GMP-regulated synthesis environments, the materials of the stirring mechanism are designed to withstand the most extreme chemical and thermal stresses. The central shaft and the anchor blades are made of solid, corrosion-resistant AISI 316L stainless steel (material number 1.4404). The flexible scrapers are made of PEEK, a semi-crystalline, high-performance thermoplastic which remains extremely dimensionally stable even at high process temperatures (up to 120 °C in the LR 1000) and exhibits outstanding chemical resistance to aggressive organic solvents, acids and alkalis. Modular cleaning and decontamination The risk of microbiological cross-contamination (carry-over) or chemical residues is particularly high when processing sticky resins or greasy gels. The LR 1000.10 anchor stirrer can be mechanically dismantled for thermal sterilisation (autoclaving) or intensive chemical cleaning. The PEEK scrapers can be easily removed from the stainless steel shaft for separate decontamination or replacement as wear parts. Technical details Product type: Anchor agitator with flexible scrapers Fluid dynamics design: Optimised for extremely high-viscosity and paste-like media Distinctive feature: Integrated, wall-skimming PEEK blades Thermodynamic advantage: Significant increase in convective heat transfer at the reactor wall Compatibility: Exclusively for IKA LR 1000 laboratory reactor systems (basic and control) Material (shaft & rotor): High-grade AISI 316L stainless steel (material no. 1.4404) Material (scrapers): PEEK (polyetheretherketone) Chemical resistance: Maximum resistance to solvents, acids and alkalis Max. permissible operating temperature: 120 °C (system limit of the LR 1000) Hygiene: Scrapers can be removed for intensive chemical or thermal cleaning Scope of supply 1 x IKA LR 1000.10 anchor stirrer (stainless steel) 1 x set of PEEK scrapers (already fitted to the anchor stirrer) (Important note: The IKA LR 1000 reactor vessel and the base station are not included in the scope of delivery!) Individual requirements & accessories The anchor stirrer is a purely mechanical component and must be used in an IKA LR 1000.1 or LR 1000.3 reactor vessel. The flexible PEEK scrapers are subject to mechanical wear when used with highly abrasive media (such as particle-laden pastes). We recommend keeping a stock of suitable replacement scrapers for your routine operations to minimise downtime. Please contact our procurement service at any time for the fluid dynamics design of your reactor and the procurement of suitable wear parts.

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.

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.

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.

Our promotional price is net.Compact, high-performance equipment for your laboratory: the IKA VACSTAR lite Starter Solution With the IKA VACSTAR lite Starter Solution (MPN 0010014496), you get a perfectly coordinated vacuum package that combines space-saving design, high suction power and environmental awareness. This 4-cylinder diaphragm vacuum pump has been developed to handle the demanding tasks of everyday life in a modern laboratory – whether as a partner for your rotary evaporator, for drying cabinets or for filtration tasks. For you, the ‘Starter Solution’ means: unpack, connect and start safely, as the essential safety emission capacitor (VSE 1) is already included in the scope of delivery. Small but mighty: performance in a minimal space The VACSTAR lite impresses with its award-winning, extremely compact design. With dimensions barely larger than a drinks bottle, this pump fits into even the smallest of nooks or directly inside a fume cupboard. But don’t be fooled by its size: with an impressive pumping speed of 22 l/min and an outstanding ultimate vacuum of 2 mbar, it’s right up there with the big players. This high pumping speed guarantees fast process times and efficient operation, even with low-boiling-point solvents. Protection for the laboratory and the environment: the safety emission condenser A highlight of this set is the included VSE 1 vacuum safety emission condenser. Vacuum pumps extract vapours that should often not simply be released into the room air. The VSE 1 reliably prevents solvent vapours from entering the laboratory atmosphere. This not only protects staff health from harmful emissions but also safeguards the environment. Furthermore, the condenser enables the effective recovery of valuable solvents, which reduces operating costs and promotes sustainable working practices. Chemical-resistant and low-maintenance As a dry diaphragm pump, the VACSTAR lite operates 100% oil-free. For you, this means: no tedious oil changes, no disposal of waste oil and no contamination of your samples by oil vapours. All parts in contact with the process fluid are made from high-quality, chemical-resistant materials (PTFE diaphragms, FKM valves, etc.). This makes the pump extremely resistant to aggressive chemicals and vapours, guaranteeing a long service life and low maintenance costs. Intuitive operation and process reliability The “lite” version focuses on the essentials: pure functionality. Operation is intuitive via a rotary knob, which allows you to continuously adjust the speed and thus the suction capacity. This enables the process to be started gently to prevent boiling delays, or ramped up to maximum performance. An integrated non-return valve also protects the system against backflow when the pump is switched off or in the event of a power cut.

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.

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.
