Bel-Art Reusable Silica Gel Desiccant Cartridges; 72 mm (2.84 in)

Reusable silica gel desiccant cartridges contain inert, non-corrosive, non-toxic silica gel for moisture control in desiccators, analytical balance cases, and precision laboratory instruments. A clear polypropylene dish allows visual inspection as the silica gel changes from blue when dry to pale pink as it absorbs moisture. The porous mesh membrane supports moisture absorption, and the cartridges can be regenerated by heating.
