SmallCorp silica gel is a type A Beaded Gel with an equilibrium moisture content of 30% and an M Value of 6.8 at 50% RH, which is especially well-suited for humidity ranges typical of most museum artifacts.
Our standard silica gel cartridge is 4”x 1”x 10” (custom sizes available) and comes with 400g of gel (all weights calculated on a dry basis). Cartridges consist of a high density polyethylene frame with polyester nonwoven fabric on both sides. Stand them on edge for maximum air exposure. The cartridge is refillable, using SmallCorp gel or other media. We offer cartridges conditioned to your specifications, or un-conditioned.
