Molecular Sieve
A material that contains many small cavities interconnected with pores of precisely uniform size.
Molecular sieves adsorb molecules that are small enough to pass through their pore systems- especially water.
They are often used as drying agents, and to separate large molecules from smaller ones in preparatory work and in exclusion chromatography.
