The Across International SolventVap 20L Rotary Evaporator is a large-capacity industrial rotovap system designed for high-volume solvent evaporation, distillation, and solvent recovery. ETL tested to UL and CSA laboratory equipment standards, this system delivers the safety, durability, and performance required by professional laboratories and production facilities.

Engineered for efficiency, the SolventVap 20L features vertical dual condensers, digital temperature and rotation controls, and a motorized lifting water bath. The rotating flask creates a thin film of solvent across the interior glass surface, dramatically increasing evaporation efficiency while reducing solvent boiling points under vacuum.

Constructed from high borosilicate glass 3.3, with solvent-resistant PTFE valves and Viton sealing gaskets, this industrial rotary evaporator is designed for continuous operation in demanding chemical processing environments.
