Molecular Sieve 3a

We are offering molecular sieve 3a. 3a molecular sieve has a pore size of 3a or 3 angstrom. Any molecule larger than 3a will not be able to be adsorbed. Mole 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.
