BÜCHI Labortechnik AG

Laboratory Rotary Evaporators

For more than 50 years BÜCHI is known for reliable and proven evaporation solutions in a wide range of industries. Whether you operate in R&D or quality control, we offer outstanding products, systems and solutions for any step in your sample preparation process. A rotary evaporator carry out single distillations and drying quickly and sparingly. The rotation increases the surface area of the mixture, thereby improving the heat transfer. The vacuum lowers the boiling point, making low-temperature distillation possible. Selecting the suitable glass configuration enables carrying out distillation and drying, extractions, (re-) crystallizations and reflux reactions as well. BÜCHI offers complete solutions for your applications, consisting of a rotary evaporator, a comprehensive vacuum system and a recirculating chiller for cooling the condensers. Combining various components enables to configure the right solution, from essential to fully automated distillation systems.

The Vacuum Pump V-300 is a chemically resistant PTFE diaphragm pump. The speed-controlled operation results in economical operation and very low noise emission. Thanks to the transparent front panel, contaminants are easily visible. It is optimally suited to work with the I-300 / I-300 Pro and R-300.

For industrial evaporation, there is the even more powerful Vacuum Pump V-600 available. More info

BÜCHI Labortechnik AG
Temperature range: -10 to 25 °C
Cooling capacity (at 15 °C): 550 to 1400 W
Pump flowrate: 2.5 - 11 liters/min.
Pump pressure: 0.6 - 1.0 bar

The BUCHI recirculating chillers are normally used with laboratory equipment that requires coolant flow such as rotary evaporators, parallel evaporators, Kjeldahl- and extraction products. The F-300 line is specifically designed for seamless integration into a Rotavapor R-300 system. The temperature can conveniently be set by the interface (I-300 or I-300 Pro). More info
