BEL Engineering Beads F.Silica Replacement Dessicant, 1 Item BELAF420740020

These colour-indicating silica gel beads are for use in refilling the Secador® auto-desiccator module which automatically regenerates them for thousands of cycles.

• Silica gel absorbs moisture from the air and is inert, non toxic and non corrosive Beads turn from blue to light pink indicating that the silica gel is saturated and cannot absorb additional moisture Beads turn pink/dark brown and fail to regain their blue colour when it is time to replace the beads with a fresh supply
