This chemistry vacuum system provides the advantageous combination of high pumping speed and low ultimate vacuum down to 70 mbar. It is therefore ideal for evacuating and pumping large amounts of gases and vapors. It has a wide range of applications in chemical, biological and pharmaceutical laboratories if condensation of solvent vapors at the outlet is not necessary. Typical applications are vacuum ovens, single and multiple filtrations, as well as concentration of solvents with low boiling points. 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.
