Seedburo dessicators are used for fast, efficient drying of prepared samples and as anaerobic culture jars. Desiccants such as sulfuric acid, phosphorous pentoxide, calcium chloride and silica gel can be used repeatedly and safely in our jars. For sustained vacuum storage, all of the ground surfaces should be cleaned thoroughly and greased with a silicone-based vacuum grease, offered below. Each dessicator is supplied with a porcelain plate.

DRIERITE INDICATING DESICCANT

This desiccant is made from gypsum (calcium sulfate) and is designed as an all-purpose drying agent. As it absorbs moisture, the desiccant changes from blue to light purple in color and can absorb 6-10% of its weight in water, depending upon the relative humidity.
