The Büchi V-710 vacuum pump is a powerful, chemically resistant diaphragm pump specifically developed for laboratory applications involving aggressive vapors and solvents.

The pump operates completely oil-free and uses a PTFE diaphragm, preventing contamination and keeping maintenance to a minimum. Thanks to the 3-stage pump system, the V-710 delivers high suction capacity and deep vacuum, making it ideal for:

Rotavap applications (rotary evaporators)

Vacuum distillation

Filtration

Drying ovens and general laboratory vacuum supply

Key advantages:

Chemically resistant (PTFE, PEEK, glass)

Very low final vacuum (up to 2 mbar)

Quiet and low vibration

Low maintenance and long service life

Suitable for continuous use
