4A Blue Indicating Molecular Sieve

mSORB® 4A blue indicating molecular sieve is an alumino-silicate with sodium as the charge balancing cation, giving it a 4 angstrom pore opening. It has the same physical properties and adsorption capacity as non-indicating 4A molecular sieve, but it is injected with cobalt chloride, a moisture indicating metal salt. The sieve is blue when dry and changes to beige when saturated with moisture. This allows the user to visually determine when the molecular sieve has reached its equilibrium capacity.

Chemical Formula: Na12[(AlO2)12(SiO2)12] • nH2O+CoCl2

Additional information

Storage

Store Blue Indicating molecular sieve in a dry location to prevent premature water adsorption. Reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so oldest material is used first.
