Wisesorb 2 lb Indicating Silica Beads 2-4mm -Blue to Pink Desiccant Bead

Wisesorb 2 LBS blue to pink Indicating Silica Gel Beads are beads of silica gel (desiccant beads), used for absorbing moisture from the air to protect things that would be adversely affected by dampness. The beads can be reactivated by placing into oven to drive off excess moisture. Dry beads show blue and turn a faintly pinkish clear color after reaching moisture capacity.

Indicating Silica Gel Beads: 2lbs indicating silica gel utilize premium quality raw material. The strong moisture absorption ability allows beads to begin to change colors at 20%RH-50%RH and will complete changing colors to pink. The beads will continue to absorb the moisture until 50%RH.

Great Absorbing Capacity: General estimate when used in an air-tight sealed container: each 40 grams of active indicating silica gel can protect up to 30 cubic ft of any enclosed storage space.

Easy to Reactivate: Each Blue indicating bead is 2-4mm in size. Once pink, place the beads into the oven to reactivate for 0.5h-3 hours at 200°F-250°F (do not over 250°F).

Widely Used: Indicating silica gel can protect any enclosed storage space such as safe, ammo cans, ammo boxes, tool box, 3D printer filament sealed plastic storage box, weapon case, closet, etc.

Independent Packaging: 2LBS blue to pink indicating silica gel beads are stored in one plastic jar for long-term preservation. The wide mouth jar makes pouring the beads back in extra easy.
