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
