The Buchi R-205 Rotary Evaporator with C glass assembly is an efficient way to evaporate and distill compounds and solvents in a compact footprint. This laboratory staple is an especially useful tool for the manufacturing of THC distillate and fine vape oil. The buchi rotovap is outfitted with a C glass assembly and cold trap for low boiling solvents using either mechanical refrigeration or dry ice with acetone. This rotavapor uses durable, chemical resistant PTFE glassware throughout the entire assembly, with quick release fittings.

The Buchi R-205 Rotovap features a motorized servo jack that effortlessly lifts and lowers the glassware on the rotary evaporator with the touch of a button, and can handle flasks between 50 Ml and 3L. The Buchi 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. 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-500 vacuum pump constructed of highly resistant material, with a maximum pressure of 10 mbar, and a V-800 digital controller for precise implementation.
