Bel-Art F42048-0100 Reusable/Disposable Desiccant Cartridges, 4" Diameter, 6/PK
Clear polystyrene dish allows instant visual inspection of silica gel, which changes in color from blue to pale pink as it absorbs moisture. A highly porous membrane covers the dish providing excellent moisture absorption. Desiccant can be easily regenerated by heating cartridges in a 50°C (122°F) oven overnight. For more rapid drying, cut the membrane, transfer the spent gel crystals into a glass or porcelain dish, and place in a 150°C (300°F) oven for one hour. Silica gel is inert, non-corrosive and non-toxic. Fits "Space Saver" desiccators, in addition to other plastic desiccators of similar size. Individually foil sealed.
