What desiccant materials are available in breathing desiccators?
The most common are molecular sieve, either Type 4A or Type 13X, or silica gel. However, any desiccant material that does not “pack” will work. When the desiccant material “packs” it can completely block the flow of air through the desiccator, rendering it non-breathable. It will still function to desiccate, but not for breathing.
