Product information "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

Maximum efficiency in dissolution and deagglomeration: the IKA S 25 KV - 26 LR dissolver The IKA S 25 KV - 26 LR dissolver (MPN 0020015397) represents the very pinnacle of modern mixing and dispersion technology for demanding laboratory reactor systems. In many industrial and research sectors – be it in chemical synthesis, cosmetics development, paint production or food technology – users face the significant daily challenge of homogeneously incorporating fine powders, highly cohesive solids or sticky pigments into liquid media. Very often, stubborn agglomerates form when these solids are stirred in. These disruptive clumps of particles are simply moved in circles by conventional agitators such as propeller, paddle or anchor agitators, but are not effectively broken up mechanically. The result is incomplete reactions, poor textures or significantly prolonged process times. This high-speed dissolver was designed precisely for these critical and energy-intensive process steps. It delivers uncompromising performance in intensive mixing, dissolution and deagglomeration to ensure homogeneous, completely lump-free dispersions in the shortest possible time. The aerodynamic dissolver principle In direct comparison to a conventional rotor-stator dispersing tool, in which the medium is forced through a very narrow, defined gap between two components, the S 25 KV - 26 LR model utilises a specially serrated dissolver disc with a diameter of 26 millimetres. This solid metal disc rotates freely at extremely high speeds (high speed) within the liquid medium. The sharp teeth on the edge of the disc, which are alternately curved upwards and downwards, generate immense local shear forces and strong turbulence. The rotation accelerates the liquid radially outwards with great force, which simultaneously creates an enormous axial suction effect (vortex formation) at the centre. This intelligent flow pattern draws the floating or agglomerated powder particles from the liquid surface directly downwards towards the rotating toothed disc. There, they are literally shattered by the high kinetic energy of the teeth and broken down into their fine primary particles. In process engineering, this principle is the absolute gold standard method for the rapid incorporation of poorly wettable thickeners, colour pigments or high-molecular-weight polymers into aqueous or highly solvent-based systems. Vacuum and pressure tightness (the ‘KV’ seal) Another outstanding feature of this stirring tool, which is indispensable for many applications, is indicated by the specific abbreviation ‘KV’. In IKA products, this stands for a high-quality ball bearing system combined with a special sealing technology that makes the tool absolutely vacuum- and pressure-tight (up to the respective system-specific limits of the laboratory reactors). When working professionally with state-of-the-art laboratory reactors such as the IKA LR 1000 control System or the versatile LR-2.ST series, this leak-tightness is of fundamental importance. Sensitive chemical reactions or the production of high-purity cosmetics and emulsions often require the strict exclusion of oxygen. Users must work under a protective inert gas atmosphere or specifically degas the sample under vacuum to avoid disruptive air pockets in pasty, viscous media. A conventional, open dispersing tool would cause the reactor chamber to leak under these extreme conditions and ruin the process. The S 25 KV - 26 LR dissolver agitator, on the other hand, seals the reactor opening absolutely securely via the flange. This allows you to deagglomerate your samples at full high-speed rotation whilst a strong vacuum is maintained inside the vessel – an enormous technological advantage for process quality. Material quality, hygiene and compatibility As this dissolver stirrer is designed for direct, continuous contact with aggressive chemicals, highly abrasive pigments and reactive media, all parts in contact with the media (including the dissolver disc and the shaft) are made from high-quality, chemically extremely resistant AISI 316L stainless steel. This industrially proven material not only guarantees outstanding resistance to most organic solvents, acids and alkalis, but can also be cleaned safely and thoroughly after use, leaving no residue. Thanks to its robust construction, the unit is ideally suited to the rigours of everyday laboratory use. As an original accessory, the S 25 KV - 26 LR is precisely matched to IKA’s reactor platforms. It is fully compatible with the T 25 digital LR disperser, the LR 1000 systems (basic and control) and the entire LR-2.ST series (including Allrounder, High Performer and Starvisc). Investing in this highly specialised tool massively increases the efficiency of your laboratory processes, significantly reduces mixing times and decisively optimises the quality of your end products.
