Dear Lab Guy, We are using an SP Bel-Art Space Saver Polycarbonate Vacuum Desiccator in the lab. I was wondering what the maximum applicable vacuum is? The manual said it hold 14 psi for 24 h but does it mean it is the max it can withstand?

Hi Lab Guy, Our customer needs to seal in a desiccator, slides with samples that needs to be transported. We would like to know the best way to do this and if you have a small desiccator with a sort of "rack" for slides. Thank you for your help. - Anna C.

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.

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.

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.
