RHapid Silica Gel [ order ]

Silica gel has been used in museums throughout the world for decades to stabilize the relative humidity (RH) in sealed exhibition cases and storage units. It provides environmental protection to museum collections by acting as a buffer against relative humidity changes.

APS developed RHapid GEL specifically for museum applications. Its unique properties give it the greatest capacity to adsorb and desorb moisture within the standard relative humidity range for artifacts in museums. RHapid GEL is the most cost-effective humidity buffering products available because less of our gel is required per cubic foot then other manufactures. The flexible, moisture-permeable packaging of the sachets allows for a simple, clean installation by museum staff.

A RHapid 6PAK is MarvelSeal® bag, which contains six, ½ pound, moisture permeable sachets of our RHapid GEL for a total of three pounds worth of gel per 6PAK. Each RHapid GEL sachet measures 4 x 6 inches and is about 1 inch high.

Based upon standard museum recommendations, one RHapid GEL sachet will condition 2 to 4 cubic feet of case volume (2 cubic feet for permanent exhibits, and 4 cubic feet for temporary applications). That is, more silica gel is required in long-term exhibition cases to provide a stable buffering environment.

Please download the article Demystifying Silica Gel for a comprehensive overview on silica gel for museum applications.

If you require more than 5 six packs of conditioned silica gel, please contact us at least a week before you need it. For especially large orders (10 six packs or more) or orders with large amounts of silica gel at different condition points please note that it may take extra time to fulfill your order.
