3A Molecular Sieve

3A Molecular Sieve

NAIKE 3A Molecular Sieve is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A molecular sieve material has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers, and this maximises lifetime when dehydrating such molecules.
