Molecular Sieve Sieves

ZEOCHEM Molecular Sieves

Molecular Sieves. Molecular sieve adsorbents are crystalline alumino-silicates, known as zeolites. Their unique structure allows the water of crystallization to be removed, leaving a porous crystalline structure. These pores or "cages" have a high affinity to re-adsorb water or other polar molecules.

3A Molecular Sieve | 3A Mol Sieves | Delta Adsorbents

3A Molecular Sieve: Has a pore size of 3A or 3 angstrom. Any molecule larger than 3A will not be able to be adsorbed. Mol Sieve is an alkali metal alumino-silicate, the potassium form of the type A crystal structure. 3 Angstrom is created when part of the sodium ions of the 4 Angstrom sieve are replaced by potassium ions. The sequence rate of adsorption rate is helium, neon, nitrogen and water.
