Recharging Desiccant Beads

Dear Lab Guy, After regenerating a cartridge desiccant in the oven at 300F for at least 3 hrs, where do you recommend keeping the hot cartridge until it cools down? I presume the cartridge should not be returned to the desiccator cabinet while hot. - Rea K.

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.

Achieving a 100% Humidity Free Environment: Vacuum and Gas-Purge Desiccation

Dear Lab Guy, I’m using a desiccator cabinet with plenty of desiccant, but it doesn't seem to produce a dry enough environment for my use. How can I achieve a lower relative humidity? Sincerely, George G.
