PROSorb is a new silica gel ideally suited to stabilize relative humidity at the recommended level inside museum display cases and storage cabinets. PROSorb has a unique and exceptional adsorption capacity through its ability to both absorb and desorb water vapor.
Use loose beads in open trays or containers. Cassettes are made of a rigid polypropylene with a vapor-permeable non-woven polyester fabric on one side and are designed to be laid flat. Re-conditioning the RH-value of a cassette can be done easily by weight.
Full-size Cassettes—size: 13.2"L x 4.3"W x 1.75"H. One or more cassettes per 30 cubic feet of air volume are required depending on application.
Half-size Cassettes—size: 13.2"L x 4.3"W x 1"H. One half-size cassette will be sufficient for 20 cubic feet of air volume depending on application
**Please specify desired humidity level (40%, 45%, 50%, 55%, or 60% RH) when ordering.
