13X Blue indicating Molecular Sieve

mSORB® 13X Blue Indicating Molecular Sieve is a porous, high capacity alkali metal aluminosilicate compound. Like non-indicating 13X molecular sieve, our blue indicating 13X molecular sieve has 10 Angstrom-sized pore openings that allow it to adsorb all molecules adsorbed by 3A, 4A, and 5A molecular sieve, plus larger molecules like aromatics and branched-chain hydrocarbons.

Chemical Formula: Na86[(AlO2)86(SiO2)106] • nH2O+CoCl2

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.

Additional information


Store Blue Indicating molecular sieve in a dry location to prevent premature water adsorption. Do not store super sacks outside; ultraviolet radiation and other adverse conditions will negatively impact its integrity and may eventually cause the bag to fail. Reseal packages after opening to prevent contamination and unintended water adsorption. We recommend that you rotate stock so the oldest material is used first.
