Molecular Sieve Drying Oven

Molecular Sieve Drying Oven

3A zeolite ceramic molecular sieve pellets used for solvent drying in the EM lab can only absorb so much water and then need to be heated to 250C to regenerate by driving off the water. Most lab ovens are rated 1 to 2 kW and barely get to 250C. This is both marginal for drying and wastes a lot of energy to bake out a small volume of sieves.
