Typical applications for chemistry vacuum systems include evacuating chemically aggressive gases and vapors from such equipment as rotary evaporators, vacuum drying cabinets and centrifugal concentrators. Chemistry vacuum systems from VACUUBRAND feature uncompromising chemistry designs. Their construction with fluoropolymers makes them very resistant to chemical vapors from inlet to exhaust and very tolerant to condensates. VACUUBRAND vacuum systems also have a gas ballast valve that provides continuous purge with minimal impact on ultimate vacuum when working with condensable vapors. Pumping chambers are hermetically separated from the drive system ensuring long lifetimes of mechanical parts.

The integrated VACUU·SELECT controller provides an easy-to-use, application based interface that covers all common lab applications. Use manual set-point-control for simple processes, run distillations, or create your own application with simple drag-and-drop editing.

For solvent evaporation, VACUU·SELECT controller detects the boiling pressure and switches to two point control to hold the pressure stable when a boiling point is detected.

• VACUU·SELECT vacuum controller with graphical user interface simplifies work in the laboratory.
• Predefined applications save time and give reproducible results.
• PTFE sandwich diaphragms and valves made of perfluoroelastomer or PTFE.
• Internal tubing and fittings made of PTFE/ETFE/ECTFE compounds.
• Exceptional diaphragm lifetimes with ultra-durable PTFE sandwich design.
• Head cover and clamping disc made of fluoro compounds with stability core for unsurpassed long-term performance.
• Very long service intervals for low lifetime cost-of-ownership.
• Patented new drive system for extra quiet, ultra-low-vibration operation (NT).
• Patented new valve mounting system to simplify service access (NT).
• Smooth surfaces for easy cleaning (NT).
• The separator at the inlet (AK) is made of glass with protective coating and retains particles and liquid droplets.
• The separator at the outlet collects condensate, avoids condensate backflow towards the pump and makes the pump whisper-quiet.
