Pump time for glasswork
When doing glasswork, how long do you wait for each pump of the pump/flush cycle? I used to wait almost no time at all, but now I'm thinking I should wait at least 5 minutes. This is because when using the mini-antechamber of the glovebox in 291, a 5 minute wait is necessary for each cycle or else oxygen will be let in.

I don't get it - Oxygen will be let in why?
The mini-antechamber has a manual pump/flush. When putting samples in, it's better to wait 3-5 minutes during each of the 3 pumps or else the mini-antechamber will not be properly flushed with N2.
