13X molecular sieve storage life | ScubaBoard

The molecular sieve must be store in an absolutely dry place immediately. Otherwise, the substance will absorb moisture from the surrounding air, reducing the absorption capacity. Storing molecular sieve in plastic bags is ineffective; plastics are water-permeable. Even aluminium-coated plastic envelopes are not entirely airtight.

Difference Between Molecular Sieve and Silica Gel ...

The key difference between molecular sieve and silica gel is that a molecular sieve is a material containing pores of similar size, whereas silica gel is a substance can be used to prepare a porous material with pores of different sizes.. Both molecular sieve and silica gel are important materials in chemical separations. They are porous materials having pores that allow some analytes to pass ...
