Product information "IKA LR 1000.3 laboratory reactor vessel, 1,000 ml, six lid connections, anchor stirrer with flow scraper, 0025001955"
The LR 1000.3 is the second reactor vessel in IKA’s LR 1000 range, designed for the same drive units as the LR 1000.1, but with a different anchor agitator and different lid connections. Instead of the standard version, an anchor stirrer with a flow scraper is fitted, which ensures thorough mixing right up to the glass wall, even with viscous media that tend to stick to the walls.
Vessel for the LR-1000 systems
Like the LR 1000.1, the LR 1000.3 is also compatible with the LR 1000 basic system and the LR 1000 control system; both provide the drive and heating for the vessel. The usable volume is based on the 1,000 ml size of the series; the base unit remains the same for both vessels, only the vessel itself is changed. This means that, if required, an existing LR 1000 system can be supplemented with a second vessel variant for other media without having to purchase a new drive unit. Those who run both low-viscosity and highly adhesive solutions in the laboratory can thus avoid the need for a completely separate system and simply swap the vessel instead.
Anchor stirrer with flow scraper and six lid connections
The anchor stirrer supplied comes with a flow scraper which scrapes the vessel wall whilst stirring, thereby preventing viscous or sticky products from sticking to the glass wall. The lid has six connections, two NS 29, two NS 14 and two GL 14, for sensors, dosing systems or other accessories. For the LR 1000.1, IKA also specifies a vacuum tap integrated into the lid; the manufacturer’s specifications make no mention of this for the LR 1000.3. The two GL 14 connections can be used for hose connections. Parts in contact with the product are made of AISI 316L stainless steel, FFKM, PTFE and PEEK. This vessel also connects to the base unit via the standardised stirrer shaft mount; this means it is possible to switch between the LR 1000 basic and LR 1000 control systems without any modifications to the vessel.
Material resistance
FFKM seals generally offer broader chemical and thermal resistance than standard FPM seals, such as those fitted to the LR 1000.1; this is particularly noticeable when dealing with more aggressive solvents or frequent changes of process medium. PEEK is used for the flow scraper because the material is mechanically robust whilst also being wear-resistant, an important consideration for a component that is constantly guided along the glass wall. AISI 316L stainless steel completes the material specification for the metal parts. Overall, the LR 1000.3 is therefore designed for more demanding media than the standard LR 1000.1 vessel; those who work predominantly with less critical, lower-viscosity solutions will generally find the more affordable standard configuration sufficient.
Typical applications
- Mixing and dispersing viscous, wall-adhering media on a laboratory scale
- Formulation development in cosmetics and pharmaceuticals
- Applications where additional lid connections are required for sensors or dosing
- Preliminary scale-up trials prior to production

Scope of delivery
- 1 x LR 1000.3 laboratory reactor vessel, 1,000 ml
- 1 x anchor stirrer with flow scraper
The drive is not included. The LR 1000 basic or LR 1000 control system must be ordered separately, as must glass stoppers or accessories for the free lid connections, should these still be missing.
Use and care
The anchor stirrer can be detached from the drive for cleaning, and the vessel itself can be completely dismantled. Those who regularly work with very sticky or highly viscous media will benefit most from the flow scraper; for thinner media, the standard anchor stirrer of the LR 1000.1 is often sufficient. The six lid ports should remain closed when not in use to prevent any liquid or steam from escaping uncontrollably whilst stirring. As with the LR 1000.1, this vessel can also be completely dismantled for thorough cleaning, which is particularly useful after processing highly sticky products.
Individual requirements and procurement service
The LR-1000 range also includes other anchor stirrers, such as the standard stirrer LR 1000.11, made of stainless steel and the LR 1000.10 with PEEK scrapers, and the flow breaker LR 1000.20 to prevent the formation of vortices in the vessel. Through our procurement service, we can assist you in selecting the drive, agitator and other accessories for your LR-1000 system, including helping you decide between the standard version and the flow scraper version.

Fits
The IKA LR 1000 control System (MPN 0025001991) is a compact laboratory reactor with a working volume of up to 1,000 millilitres, which combines stirring, heating and digital process documentation in a single unit. Unlike the simpler LR 1000 basic System, this model features a large TFT display showing all process values, supplemented by a connection for external pH measurement and digital interfaces for PC connectivity. The system is suitable for stirring and heating processes involving media with a viscosity of up to 100,000 mPas and operating temperatures of up to 120 °C, for example in chemical synthesis, formulation development or quality control. Thanks to the additional sensor technology, reactions can be monitored and documented much more closely than with a simple magnetic stirrer. Anchor stirrer with PEEK scrapers and torque trend measurement The supplied LR 1000.10 anchor stirrer is fitted with PEEK scrapers which continuously glide along the inner wall of the reactor vessel, thereby preventing product from depositing on the heated glass wall. The speed range extends from 10 to 150 revolutions per minute at a nominal torque of 3 Nm, suitable for media with a viscosity of up to 100,000 mPas. An integrated torque trend measurement indicates how the consistency of the stirred material changes during the process, for example when a solution becomes increasingly viscous or a solid dissolves. Heated reactor vessel with precise temperature control The LR 1000.3 reactor vessel has a maximum capacity of 1,000 millilitres; with a dispersing tool fitted, the minimum volume is 500 millilitres. The heating element at the base of the vessel has a heating power of 1,000 watts and heats the medium to operating temperatures of up to 120 °C, whilst the heating plate itself can reach temperatures of up to 180 °C. The supplied PT 100.30 temperature sensor measures the medium temperature with a resolution of 0.1 Kelvin; the control accuracy is ±0.2 Kelvin, and the setting accuracy is ±1 Kelvin. TFT display, pH connection and digital interfaces A large TFT display shows speed, temperature and other process values in real time. An external pH electrode can be connected via a BNC socket, covering a measurement range from 0 to 14 pH with a resolution of 0.1 pH, allowing acid-base reactions to be monitored directly in the reaction vessel. In addition, the system features an integrated weighing function with a weighing range of up to 2,000 grams at a resolution of 1 gram. An RS 232 interface, a USB port (Micro-B) and Bluetooth are available for connection to a PC for process documentation. Vacuum operation and safety concept The system is designed for operation under vacuum down to 25 mbar; a vacuum valve assembly controls the connection to a vacuum pump. Two hose connections also allow an external cooling medium with a minimum temperature of 3 °C to be connected, for example to cool exothermic reactions in a controlled manner. An adjustable safety circuit monitors the temperature within a range of 47 to 225 °C with a tolerance of ±10 to ±20 Kelvin and automatically switches off the heating if necessary. If the reactor vessel or lid is removed during operation, a safety shut-off is triggered immediately. Difference from the LR 1000 basic System Within the LR 1000 series, the control System is the version with more comprehensive data logging: Whilst the simpler LR 1000 basic System is primarily designed for stirring and heating, the control System adds pH measurement, an integrated weighing function and digital interfaces for process documentation. Anyone requiring comprehensive documentation of temperature, pH and torque curves, for example for internal quality records, is better served by this version than by the basic model. Typical applications The LR 1000 control System is suitable for stirring, heating and documentation tasks on a 1-litre scale, wherever process data needs to be recorded in a traceable manner: Chemical syntheses with temperature control and concurrent pH monitoring Formulation development in the cosmetics and pharmaceutical industries involving process parameters subject to documentation requirements Vacuum-assisted concentration or degassing of solutions and dispersions Polymerisation experiments in which torque trends and viscosity increases are to be monitored simultaneously Quality control with documented temperature and pH profiles for internal release processes Practical courses and further training in which students learn how to operate a fully equipped laboratory reactor Formulation screening, in which several batches with different temperature profiles are compared sequentially Technical details Max. usable volume1,000 ml Minimum volume with dispersing tool500 ml Speed range10 to 150 rpm Rated torque3 Nm Max. viscosity100,000 mPas Operating temperature (medium) max.120 °C Max. heating temperature (heating plate)180 °C Heating power1,000 W Control accuracy (medium)±0.2 K Setting accuracy of target temperature±1 K Achievable vacuum25 mbar Weighing rangeup to 2,000 g, resolution 1 g pH measurement range0 to 14 pH, resolution 0.1 pH Material (parts in contact with the medium)Borosilicate glass 3.3, AISI 316L stainless steel, PEEK, PTFE, FFPM Connections on reactor lid2 x NS 29, 2 x NS 14, 2 x GL 14 DisplayTFT display InterfacesRS 232, USB (Micro-B), Bluetooth Dimensions (W x H x D)443 x 360 x 295 mm Weightapprox. 23 kg Mains voltage230 V, 50/60 Hz Power consumption1,200 W Permissible ambient temperature5 to 40 °C Permissible relative humiditymax. 80 % Scope of delivery 1 x IKA LR 1000 control base station 1 x LR 1000.3 reactor vessel 1 x LR 1000.10 anchor stirrer with PEEK scrapers 1 x PT 100.30 temperature probe with mounting bracket 1 x support rod, 16 mm diameter 2 x hose connectors for cooling medium 1 x USB cable (USB-A to Micro-B, 2 m) Individual requirements and procurement service To help you expand your LR 1000 control System, our procurement service can assist you with additional accessories, such as a pH electrode with a BNC connector, further reactor vessels or dispersing tools for the open lid ports.

For stirring and heating processes on the 1-litre scale that do not require pH measurement or digital process documentation, the IKA LR 1000 basic System laboratory reactor (MPN 20119960) offers the basic equipment of the LR 1000 reactor platform. It processes media with a viscosity of up to 100,000 mPas in a working volume of up to 1000 millilitres and heats the medium to working temperatures of up to 120 °C. As the entry-level version of the LR 1000 series, it suits laboratories that need a compact, heated laboratory reactor without the additional sensors of the LR 1000 control System. Operation therefore stays reduced to the essentials: set the speed, set the temperature, stir. Speed control up to 100,000 mPas The speed range of the LR 1000 basic System extends from 10 to 150 revolutions per minute at a rated torque of 3 Nm, with a maximum speed deviation of ±5 revolutions per minute. This allows media with a viscosity of up to 100,000 mPas to be stirred in a controlled way. The system is designed for continuous operation at 100 % duty cycle, so longer reactions or multi-hour stirring processes can be run without interruption. Heated reactor vessel with 1000 millilitres working volume The reactor vessel holds a maximum of 1000 millilitres. With a dispersing tool the minimum volume is 500 millilitres, without a dispersing tool it is 300 millilitres. The heater delivers a heating power of 1000 watts and warms the medium to up to 120 °C, while the heating plate itself can reach temperatures of up to 180 °C. Temperature control works with an accuracy of ±0.2 kelvin at the medium and a setting accuracy of ±1 kelvin for the target temperature. The system is also designed for vacuum operation down to 25 mbar. Compact design with connection for external temperature probes With dimensions of 443 x 360 x 295 millimetres and a weight of around 22 kilograms, the LR 1000 basic System fits into a modest footprint in the laboratory. An external temperature probe can be connected via a PT100 connection, and two additional hose nozzles allow connection of an external cooling medium, for example to cool exothermic reactions in a controlled way. An RS 232 interface and a USB port are available for connection to a PC. Material and resistance The media-contacting parts are made of borosilicate glass 3.3, stainless steel AISI 316L, PTFE and PEEK. The seals are made of FKM and, together with the chemically resistant glass, make the system suitable for both aqueous and solvent-based batches. The permissible ambient temperature is 5 to 40 °C, the permissible relative humidity a maximum of 80 %. Vacuum operation for degassing and solvent-free working In addition to classic stirring and heating at normal pressure, the LR 1000 basic System can also be operated under vacuum down to 25 mbar. This is helpful, for example, when air bubbles are to be removed from a viscous formulation, or when a solvent is to be removed gently at reduced pressure and therefore lower temperature, instead of heating the medium to its boiling point at normal pressure. Difference from the LR 1000 control System The basic System covers the basic stirring and heating functions of the LR 1000 series, but omits the TFT display, pH measurement, integrated weighing function and Bluetooth connection of the LR 1000 control System. For applications where pure temperature and speed control without additional measurement data acquisition is sufficient, the basic System is therefore the more economical choice within the series. Typical applications The LR 1000 basic System is suitable for stirring and heating processes on the 1-litre scale without additional documentation requirements, wherever a solid basic equipment level is sufficient: Stirring and heating reaction batches in chemical synthesis Homogenising and temperature-controlling creams, gels and emulsions in cosmetics development Vacuum-assisted degassing or concentrating of solutions Formulation development in early pharmaceutical development Practical courses and training in which the basic handling of a heated laboratory reactor is taught Routine processes in which temperature and speed must be kept constant and no pH measurement is required Smaller batches in materials development where external temperature monitoring via PT100 is sufficient Preliminary trials to test new recipes before a process is transferred to the more extensively equipped control System Technical details Max. working volume1,000 ml Min. volume with dispersing tool500 ml Min. volume without dispersing tool300 ml Speed range10 to 150 rpm Speed deviationmax. ±5 rpm Rated torque3 Nm Max. viscosity100,000 mPas Working temperature (medium) max.120 °C Heating temperature (heating plate) max.180 °C Heating power1,000 W Control accuracy (medium)±0.2 K Setting accuracy target temperature±1 K Achievable vacuum25 mbar Permissible duty cycle100 % Material (media-contacting parts)Borosilicate glass 3.3, stainless steel AISI 316L, PTFE, PEEK, FKM InterfacesRS 232, USB Connection for external temperature probePT100 Dimensions (W x H x D)443 x 360 x 295 mm Weightapprox. 22 kg Permissible ambient temperature5 to 40 °C Permissible relative humiditymax. 80 % Scope of delivery 1 x IKA LR 1000 basic base station 1 x Reactor vessel 1 x Sensor holder 1 x Temperature probe 1 x Stand rod 2 x Hose nozzles for cooling medium Individual requirements and procurement service To extend the LR 1000 basic System, we support you through our procurement service with additional accessories, for example further reactor vessels, dispersing tools or a move to the more extensively equipped LR 1000 control System.
