Description
D-LAB membrane pumps with their chemically resistant Teflon® heads, diaphragms and Kalrez® valves, offer the chemical or pharmaceutical laboratory user a wide range of choice.
The one head, 100 mbar ultimate vacuum pumps are suitable for use with drying equipment or for replacing water-jet pumps, whilst the two head, 8 mbar ultimate vacuum pumps are suitable for rotary evaporation, gas transfer and a wide range of medium vacuum applications.

Technology
- The vacuum pumps are gas-tight, 100 oil-free, maintenance-free and quiet.
- High ultimate vacuum and fast pump down time.
- All parts of the pump head in contact with gases being pumped are resistant against aggressive substances (materials: PTFE, FFKM, PVDF).
- New valve system is very tolerant of water vapour and condensates.
- Illuminated switch on pump.
- Overload protection by means of thermal cut-out.
- Compact design with space saving dimensions.
- Changing the diaphragms and valves in the vacuum pumps is a simple procedure.
- The individual system components are easily integrated into one unit which can be progressively expanded.
- The entire unit is mounted on a sturdy baseplate which makes it safe and easy to transport.
- Individual components are easily removed because they all have plug in connectors.
- Additional laboratory equipment can easily be mounted on the groove holding the separator or on the support rods and horizontal bars..
