20 g indicating

The 20 gram Indicating sachets made with standard wrapping are small type desiccant products.

This particular silica gel with a totally safe, inert, Cobalt and DMF free color indicator changes color when exhausted, passing from yellow (active) to blue (saturated). This allows you to accurately check when the silica gel has exhausted its dehydrating capacity and must therefore be replaced.

Each sachet absorbs almost 4 grams of water and therefore find application in very small containers where the volume to be dehydrated is contained. They can be used for dehydrating bottles, small boxes, stamp collections or documents.
