LC-S212-2L Double-Layer Glass Reactor, 2 L and 1100 rpm (CAT#: STEM-BC-3662-ZJF)

The LC-S212-2L is a jacketed glass reactor for small-batch laboratory synthesis and processing. It performs constant-speed stirring, reaction, evaporation, separation, and solvent recovery under reduced pressure. The 2 L GG-17 glass vessel provides chemical resistance and clear visibility of the reaction mixture. Circulating heating or cooling fluid can pass through the 0.5 L jacket. The electronic drive provides stepless stirring adjustment from 0 to 1100 rpm. A PTFE-coated stainless-steel shaft supports mixing of corrosive and solvent-based materials. Fluororubber and PTFE sealing components maintain vacuum performance during operation. The five-port cover, condenser, feed funnel, vacuum gauge, and PTFE discharge valve provide flexible process connections.
