Bel-Art Lab Companion cabinet style vacuum desiccator F42400-4011_12 - Ask Lab Guy

Vacuum Desiccator Takes a LONG Time

Dear Lab Guy, I have the F42400-4011 35 liter clear cabinet desiccator that I just purchased. I got it to pull the vacuum I need using an inline vacuum pump that has a free air capacity of 3.2. My dilemma is that it takes more than a minute to evacuate the chamber. Is this just pretty much the standard time or could I improve on this with a larger capacity vacuum pump? Thank you, Melissa E.
