13X Blue indicating (Moisture Indicating) Molecular Sieve
In addition to all of the same physical properties and behaviors as non-indicating molecular sieve, blue indicating molecular sieve has the additional bonus of allowing the user to visually determine when it has reached saturation. When the beads are dry, they are blue, and when they have reached their adsorption capacity they become beige.
