Molecular sieves are crystalline, synthetic zeolites. Their crystal gratings are similar to a cage with numerous hollow spaces. The cavities are accessible from all sides by pores of exactly defined dimensions.

Molecular sieves can be used:     

in desiccators and drying tubes     

for keeping absolute solvents dry     

for drying gases or solvents in drying columns   

for selective adsorption
