Can I Mix It? Working Space in the Benchtop Fume Hood

Dear Lab Guy, I need to see a video of the Bel-Art H50000-0002 in action. I need to mix the contents of qty=2, one gallon cans into a common 1 quart container and need to see how much real working space is in the device. Thanks, Mark

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.
