Suitable for all Hei-VAP Rotary evaporators. Vacuum can be controlled manually or via valve operated vacuum controllers.

With two-stage diaphragm pump
All components which come in contact with media are built from chemically resistant fluoropolymer
The durable PTFE design guarantees an superior diaphragm lifespan
The head cover and clamping disc have a stable core made of metal which offers unsurpassed long-term performance of your operational parameters
The direct pump drive (without belt) is exceptionally quiet, creates a very low vibrational environment and reduces the need of wear and tear parts to a minimum
The gas ballast valve has been optimized to prevent media condensing in the pump
The pumps can be combined with a condenser
For combination with the Hei-VAP Precision Rotary evaporators a vacuum valve is necessary.

Recommended for solvents with low or medium boiling points.
