Büchi R-210 Rotavapor with B-491 digital heating bath

Büchi R-210 Rotavapor (rotary evaporator), complete with a B-491 digital heating bath, a glass condenser, and a 1-liter receiving flask.

The Büchi R-210 is a reliable laboratory rotary evaporator designed for the efficient evaporation, concentration, and recovery of solvents under reduced pressure (vacuum). The system is suitable for applications in chemical, pharmaceutical, biotechnological, and analytical laboratories.

The rotation speed is adjustable from 20 to 280 revolutions per minute (rpm). The unit accommodates evaporation flasks with capacities ranging from 50 to 4000 ml.

The R-210 features an electric lift, allowing the evaporation flask to be easily lowered into or raised out of the heating bath. For added safety, the system includes an automatic lift function: in the event of a power failure, the evaporation flask is automatically raised out of the heating bath.

The accompanying B-491 heating bath features a robust stainless-steel interior and a digitally adjustable temperature range of 20 to 180 °C. The LCD display shows both the set temperature and the actual bath temperature.

The glass condenser facilitates the condensation and collection of evaporated solvents. When combined with a vacuum pump, the system can be used efficiently for a wide range of evaporation processes. Included components
