Color-indicating silica gel beads for use in refilling the Secador auto-desiccator module; silica gel absorbs moisture from the air and is inert, non-toxic and non-corrosive
Unlike other desiccants, silica gel is non-friable and won't disintegrate into powder even after repeated regeneration
Beads contain a color-changing moisture indicator that turns from blue to light pink, indicating that the silica gel is saturated and can not absorb additional moisture
Secador auto-desiccator modules automatically regenerate the silica gel beads for thousands of cycles
However, when beads turn ink/dark brown, and fail to regain their blue color, it is time to replace the beads with a fresh supply
