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 information

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 information
