Products
A rotary evaporator, or rotovap, removes solvent from a solution by rotating a heated flask under reduced pressure: lowering the pressure drops the solvent's boiling point so it evaporates gently, while rotation spreads a thin film over the flask wall to speed evaporation and prevent bumping. The vapor travels to a chilled condenser and collects in a receiving flask. In cannabis processing this is the workhorse for ethanol recovery after winterization and for concentrating crude extracts before distillation.
A rotovap only performs as well as the system around it. The heating bath sets evaporation temperature, the vacuum source lowers the boiling point, and a chiller or cold condenser recaptures the vapor; if any one is undersized, recovery slows and solvent is lost to the pump. The catalog spans flask sizes from about 2L to 50L. Benchtop 2L-5L units suit lab-scale and R&D, while 20L and 50L units target production-scale solvent recovery throughput.
Lift style matters for daily use: a manual lift raises and lowers the flask by hand, while an auto (motorized) lift does it at the press of a button, which is safer and easier with heavy large-format flasks. Choose by batch volume and solvent first, then confirm the bath range, condenser surface area, vacuum level, and chiller capacity all match, and that the glassware and seals are compatible with your solvent.
