The Buchi R-205 Rotary Evaporator is a compact and efficient way to evaporate and distill and is a laboratory staple. It is an especially useful tool in the manufacturing of THC distillate and fine vape oil. This modular rotovap is outfitted with a cold trap, C Glass assembly, making it an ideal set up for low boiling solvents using either mechanical refrigeration or dry ice with acetone. The R 205 has a digital control and display that shows you not only the speed at which the rotavap is operating but also the temperature of the vapor, letting you monitor progress.


The Buchi R-205 Rotovap glassware is coated with durable, chemical resistant PTFE throughout the entire assembly. The servo jack on this buchi rotary evaporator is motorized to lift and lower glassware on the rotary evaporator effortlessly with the touch of a button, and can handle flasks between 50 mL and 3L. This rotary evaporator is partnered with a B-490 heating bath , with a temperature range of between 20 to 180° C (68-356°F) that can be used with either oil or water. The R-205 is also partnered with a V-700 vacuum pump constructed of highly resistant material, with a maximum pressure of 2 mbar, and a V-850 digital controller for precise implementation.
