LC-S212-3L Double-Layer Glass Reactor, 3 L and 90 W Stirring (CAT#: STEM-BC-3663-ZJF)

The LC-S212-3L is a medium-capacity double-layer glass reactor for laboratory reaction processes. It supports homogeneous mixing, evaporation, separation, and solvent recovery under vacuum. The 3 L transparent GG-17 vessel enables continuous observation of reaction behavior. Its 0.6 L jacket connects to external heating or cooling equipment for temperature control. A 90 W motor provides stepless agitation from 0 to 1100 rpm. The PTFE-coated stainless-steel stirring shaft withstands contact with a wide range of solvents. PTFE and fluororubber sealing technology helps sustain a vacuum level of 0.098 MPa. A larger condenser, 500 mL constant-pressure funnel, five-port cover, and angled discharge valve support efficient operation.
