Sometimes moisture in the air can alter a chemical or item or cause it to become ineffective. Desiccators are enclosures that hold hygroscopic powders and substances that act as drying agents. A water-sensitive material or object impacted by water or humidity can be enclosed in the desiccator with the desiccant to extract the moisture, or protect the item from water in the air. Product variations include vacuum desiccators, non-vacuum desiccators, glass or plastic, capacity, inclusions and other considerations.
