What is a MoistureStop Desiccant Pouch, how is it used, and why should I use it?

The MoistureStop Desiccant Pouch is a small, airtight zipper bag which contains a desiccant packet. It is utilized to desiccate while cooling all of the Filter Bags that are used with ANKOM instrumentation. A single pouch can hold a full run of F57, F58 or XT4 bags at one time. When folded, 6 IDF or SDF bags can also be placed into a MoistureStop Desiccant Pouch. The small headspace volume of the MoistureStop Desiccant Pouches yield better moisture control than larger benchtop desiccators. Each time a bag has been removed from the desiccant pouch, the air must be pushed out. The zipper does not have to be closed between bag removals but some action should be taken to keep the air from entering the pouch while individual bags are weighed. The desiccant packet inside the zipper bag must be renewed just like any other desiccant material - by drying in an oven at 100° - 105 ° C for a few hours. The color (blue) of the desiccant is an incidation that the desiccant is dry and active. If the contents are any other color, the desiccant is no longer absorbing moisture. The zipper bag should be replaced from time to time to ensure the integrity of the bag. A benchtop desiccator will introduce too much moisture to the filter bags when it is opened and may skew results.
