BVV™ Molecular Sieve Beads Type 4A - 308LB vacuum pump Use reverse osmosis water orMolecular Sieve Beads Type 4A This bag contains both blue moisture indicating molecular sieve and also normal molecular sieve. The blue molecular sieve is a sodium alumina silicate molecular sieve impregnated with an inorganic metal salt moisture indicator. The desiccant will perform as a 4a molecular sieve plus with the additional ability to visually determine when the molecular sieve reaches saturation. When active, the molecular sieve beads are
