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.
Vacuum Pumps Rotavac Vario Control
