Blue Indicating Molecular Sieves Type 4A are crystalline metal aluminosilicates having an effective pore opening of 4 angstroms. Type 4A are the sodium form of the Type A crystal structure and represent the basic structure for the Type A family of Molecular Sieves. The
Molecular Sieves are impregnated with cobalt chloride (blue indicator). They gradually change from blue color in the activated condition to pink/beige color in the saturated condition.
The Blue Indicating Molecular Sieves are used as a combination of desiccant and relative humidity indicator.
Types 4A and 13X are delivered in drums containing 55 lbs net of product. (Please contact us for special packaging).
