The Economy Desiccators consist of a plastic container with a vacuum pump that dries, preserves, stores, and even ships samples. Built-in vacuum pump removes air with manual strokes.
Rubber O-ring sealed cover maintains vacuum of better than 200" of H2O or 15" of Hg. A release button allows air into the container to remove the lid. Vacuum indicating button confirms interior vacuum and a dial hygrometer that displays 0 to 100% RH with a resolution of 2% RH.
