Arrow Pneumatic (ARRP34189) PneuMasterAir Replacement Desiccant - 1 Quart

• Sold Individually

This is the actual Dissicant material that would be used in a dissicator to absorb moisture from air. It starts out a dark blue color and changes to a pink color when it needs to be replaced or rejuvenated. Unlike some of the bag dissicants it doesn't seem to have a noticeable odor.

I use this in conjunction with my vacuum dissicator. If you have a refrigeration type vacuum pump you can quickly rejuvenate it by pulling a good vacuum on it for a few minutes until the pump stops blowing out moisture and the pressure goes a bit lower or until the dissicant turns a cobalt blue. The other option for rejuvenating Dissicant requires heat and is slower.

This is economical and seems to be good quality. I like the color change since it shows when you need to replace or rejuvenate it.
