5 LBS Orange Indicating Silica Gel Desiccant Beads Reusable Industry Standard 3-5 mm, Rechargeable Silica Gel Beads for 3D Filament, Electronic, Camera, Jewelry 15PCS Organza Bag

About Desiccant Beads: Silica gel size is the industry standard of 3-5 mm and is not suitable for drying flowers. It offers outstanding moisture absorption, taking in up to 35% of its own weight, effectively pulling moisture from enclosed storage spaces to protect items from damage.
Color Indication: The orange silica gel shifts to green when 50-60% saturated with moisture. The first color change does not mean full saturation; the desiccant keeps absorbing moisture until it reaches 50-60% RH, then turns dark green. It is advised to inspect the color of the silica gel beads regularly to maintain their performance. Silica gel beads are safe and free of cobalt chloride.
Rechargeable: These reusable desiccant beads can be refreshed by heating them in an oven for 0.5 to 2 hours at 200 to 250°F, or in a microwave for 7-10 minutes at 700W, until all beads become bright orange. Depending on the state of the silica beads, less time may be needed than suggested; check the beads' color from time to time.
Packaging and Collection: The set contains 15 organza bags and 5 lbs of rechargeable desiccants, sealed in an airtight barrel. A double-sealed airtight barrel is used for extended storage and safeguarding.
Wide Application: This color-changing desiccant is suitable for a broad range of everyday uses. Employ it to guard against moisture damage to 3D printer filament, air compressors, cameras, documents, jewelry, gun safes, clothes, and numerous other valuables
