Color-indicating silica gel beads for use in refilling the Secador® auto-desiccator module.

• Color-changing moisture indicator beads
• Inert, non-toxic, and non-corrosive
• Replacement beads indicate moisture saturation and replacement time

Silica gel absorbs moisture from the air and is inert, non-toxic and non-corrosive

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 pink/dark brown, and fail to regain their blue color, it is time to replace the beads with a fresh supply.

Unlike other desiccants, silica gel is non-friable and won’t disintegrate into powder even after repeated regeneration.
