Molecular Sieve Beads 4A (Indicating)

Molecular sieve is a synthetically crystalline metal alumosilicate zeolite.

Molecular sieve particles have a uniform pore structure that enables molecular sieve to separate molecules by size. This pore structure provides a high capacity for water absorption at very low humidity levels while allowing molecular sieve to retain a higher percentage of moisture capacity at elevated temperatures.

This molecular sieve is indicating and will change color when saturated.
