    Yes, but we’d also put a liquid nitrogen trap in the circuit between pump and vacuum line to prevent the pump oil absorbing volatiles and reducing the efficiency, and I’d like to see the Swindon drawing for that!

    As long as they don't condense oxygen ;)
    (Something I have never done and raises an eyebrow when someone says they have)

    I always managed to avoid that one in several years of standing by a Schlenk line!

    If you do it properly, you should avoid it!

    It is labelled both Air Pump and Vacuum Pump.

    I suppose it could be called the "Vacuum Maintaing Air Pump" :)

    But what really matters is, why does it squeak?
    Is that a fault, or is it an indication of a good seal around the piston?

    I’m not going to comment on the cause of the squeak in case it leads to another forty posts!!!

    Most other industries call that device an Exhauster.
