Product information "IKA LR-2.ST the Allrounder Laboratory Reactor, 500 to 2000 ml, up to 100,000 mPas, 20013292"
A laboratory that works on formulations from very different projects can rarely predict which viscosity the next batch will bring. The IKA LR-2.ST the Allrounder laboratory reactor (MPN 20013292) is the version with the broadest coverage within the LR-2.ST reactor platform and processes media up to a viscosity of 100,000 mPas at a working volume of 500 to 2000 millilitres. It thus covers most of the viscosity ranges found in practice and is particularly suitable for laboratories that are not tied to a single product category but switch between very different recipes over the course of a project.
EUROSTAR 200 control for high viscosities
The Allrounder is factory-fitted with the EUROSTAR 200 control laboratory stirrer, which delivers a maximum torque of 200 Ncm at the stirring shaft, more than three times that of the entry-level version the Compact Power. The speed range of 8 to 290 revolutions per minute matches that of the other LR-2.ST versions, so process data can be compared within the series. The microprocessor-controlled regulation keeps the speed stable even with viscous, high-viscosity media and, via the integrated torque trend display, shows how the consistency of the stirred material changes during the process.
Reactor vessel with vacuum operation down to 25 mbar
The 2.0-litre borosilicate glass reactor vessel operates in a temperature range from room temperature to 230 degrees Celsius and is designed for a working volume of 500 to 2000 millilitres. The LR2.10 reactor lid provides three openings in standard ground joint NS 29/32 and two more in standard ground joint NS 14/23, through which, for example, a temperature probe, a reflux condenser or a dispersing tool can be connected. Seals made of FFPM (perfluoroelastomer) provide for vacuum operation down to 25 mbar and are both chemically resistant and durable across the entire temperature span of the system.
Compact design despite high torque reserve
Despite the stronger drive compared with the Compact Power and the Versatile, the Allrounder, with dimensions of 460 x 1240 x 430 millimetres, a telescopic foot stroke of 390 millimetres and a weight of around 25 kilograms, remains just as compact as the other LR-2.ST versions. The detachable wireless control unit WiCo can be operated from outside the fume hood, which reduces direct contact with the reactor when stirring critical media. Permissible ambient temperatures are 5 to 40 degrees Celsius at a maximum of 80 per cent relative humidity, conditions that are generally met in a normally air-conditioned laboratory room without additional measures.
Five lid openings for individual experimental set-ups
Through the five standard ground joint openings in total of the LR2.10 reactor lid, additional temperature probes, a dropping funnel, a gas inlet and outlet line or a dispersing tool can be introduced depending on the test series. Since the Allrounder is intended for a broad range of applications anyway, it benefits particularly from this flexibility: a laboratory can keep using the same basic set-up for very different projects instead of buying a separate reactor for each new application. This versatility pays off noticeably, especially in contract laboratories with changing customer projects.
Broad coverage as the most frequently chosen configuration in the series
With a maximum viscosity of 100,000 mPas, the Allrounder covers considerably more applications than the Compact Power (50,000 mPas) and the Versatile (70,000 mPas), but remains below the High-Performer in price, which is designed for viscosities up to 150,000 mPas. For laboratories that do not know definitively which consistency future batches will reach, this middle-to-upper configuration of the LR-2.ST series therefore often offers the most practical balance between investment cost and reserve for unexpectedly viscous media.
Typical applications
The LR-2.ST the Allrounder is suitable for a broad range of stirring and mixing tasks with medium to high viscosity, regardless of the respective product class:
- Chemical syntheses in which the viscosity changes significantly during the reaction
- Production and homogenising of adhesives, sealants and similarly viscous formulations
- Cosmetics and pharmaceutical development with creams, gels and highly concentrated emulsions
- Vacuum-assisted degassing of viscous media before filling or further processing
- Multi-project laboratories in which changing product classes with different consistencies are handled
- Scale-up preliminary trials in which the later production viscosity is to be reproduced on a laboratory scale
- Practical courses and in-house training in which a single reactor is used for several different exercise batches
- Contract development with changing customer projects and correspondingly different product viscosities

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.
