Wisesorb Silica Gel Indicating Beads 900g – Orange to Dark Green, Reusable Desiccant

Wisesorb Silica Gel Indicating Beads 900 g – Reliable Moisture Control You Can See

Stop guessing whether your desiccant is still working. Wisesorb's colour-indicating silica gel beads change from orange to dark green as they absorb moisture, giving you a clear, at-a-glance signal — no testing equipment needed. Cobalt chloride-free and safe for everyday use.

Key Features

• Cobalt-Free Colour Indicator (2–4 mm beads) – Beads gradually shift colour as humidity rises (20–50% RH), turning dark green when saturated. A colour change does not mean immediate saturation — beads continue absorbing up to ~50% RH.
• High Absorption Capacity – 40 g of silica gel can protect up to 30 cubic metres of enclosed space. Ideal for airtight containers, safes, ammo boxes, and storage cabinets.
• Reusable with Oven Regeneration – Regenerate at 90–120°C (do not exceed 120°C) for 30 minutes to 3 hours until beads return to orange. Note: absorption capacity may gradually decrease with each regeneration cycle; replace when performance noticeably declines.
• Versatile Container Compatibility – Use in mesh bags, tea filter bags, organza bags, muslin bags, mason jars, or any breathable pouch to suit your storage setup.
• Safe & Non-Toxic – No cobalt chloride. Safe for home, workshop, and professional environments.

Frequently Asked Questions

When should I regenerate the silica gel?
When the beads have turned mostly dark green, it’s time to regenerate. Place them in an oven at 90–120°C for 30 minutes to 3 hours until they return to orange. Do not exceed 120°C.

Does a colour change mean the beads are fully saturated?
Not immediately. The beads begin changing colour at around 20% RH and continue absorbing moisture up to approximately 50% RH. Monitor regularly and regenerate when mostly dark green.

How many times can I reuse the silica gel?
Wisesorb silica gel beads are designed for multiple reuse cycles. However, absorption capacity may gradually decrease with each regeneration. Replace when you notice a significant drop in effectiveness.

Is this product safe to use near food, firearms, or electronics?
Yes. These beads are cobalt chloride-free, non-toxic, and non-corrosive, making them safe for use in a wide range of environments including gun safes, camera bags, and dry food storage areas.

How much silica gel do I need?
As a general guide, 40 g of silica gel can protect up to 30 cubic metres of enclosed space. Adjust quantity based on the size of your container and local humidity levels.
