IKA lab reactors are the ultimate systems when it comes to optimizing and reproducing chemical reaction, mixing, dispersing, and homogenization processes on a lab scale. The lab reactors can be individually customized to perform numerous tasks, including: production of crèmes and lotions, and the grinding and disintegrating of solids and fibers in liquids or polymers. Single-walled or double-walled vessels made from borosilicate glass or stainless steel are available, each with or without bottom discharge valve. Functionality, safety, and longevity are the main goals in the development of IKA laboratory reactors.


LR-2.ST laboratory reactor :
The IKA® LR-2.ST system is a modulary designed miniplant reactor system, planned and designed to simulate and optimize chemical reaction processes as well as mixing, dispersion and homogenization processes at a model scale with a maximum volume of 2000 ml.
Depending on the seal (FFPM), the medium in the reactor vessel can be heated up to 230 °C. Vacuum operation is possible up to 25 mbar. The IKA® laboratory software labworldsoft® is providing convenient solutions for measuring, control, regulating tasks and documentation purposes. The system is planned and designed to simulate and optimize chemical reactions processes as well as mixing, dispersion and homogenization processes at a model scale.

  • Volume max.: 2000 ml
  • Volume min. (stirring): 500 ml
  • Volume min. (dispersing): 800 ml


Some applications are:

  • Manufacturing cremes, lotions, emulsions
