BUCHI Vacuum Pump V-300

The economical and silent vacuum source. The chemically resistant PTFE diaphragm vacuum pump impresses with its very silent and economical operation. With a flow rate of 1.8 m3/h and an ultimate vacuum of 5 mbar, it is optimally suited to be combined with the Rotavapor® R-300.

  • – Quiet operation thanks to speed regulation
  • – Unattended operation in combination with Interface I-300 / I-300 Pro when combined with optional level sensor for secondary condenser that alerts potential overflow of the receiving flask
  • – Seamless plug and play integration into a speed-controlled vacuum system with Interface I-300 / I-300 Pro, or a fully automated BUCHI Rotavapor® R-300 system including all process parameters

Seamless Integration

Convenient temperature setting and control when integrated in a Rotavapor® R-300 system.


A set vacuum is achieved very precisely by means of speed-control operation. Due to the absence of sudden pressure changes bumping is minimized.

Visible membranes

Condensed solvents or particles are easily visible thanks to the transparent front panel.

Quiet operation

Thanks to speed-control, the pump operates smoothly to keep the set vacuum. This results in very low noise emission (32 dB).

Secondary condensor

The optional post-pump condenser captures vapor which is otherwise released into the lab atmosphere.

Level sensor

In combination with the Interface I-300 / I-300 Pro an optional sensor alerts the operator to empty the receiving flask when required.
