v 300The chemically resistant PTFE Vacuum Diaphragm Pumps 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


  • High chemical resistance due to the use of high quality materials
  • Increased lifetime thanks to speed-controlled operation in conjunction with the optional Interface I-300 / I-300 Pro
  • Easy visual detection of condensate and particles due to transparent front panel


Seamless plug & play integration into:

  • A speed-controlled vacuum system with Interface I-300 / I-300 Pro
  • A fully automated BUCHI Rotavapor® R-300 system including all process parameters

11595146 V 300 PB A4 en ASpeed controlledSeamless 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 minimised. 

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 condenser
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.
