Silica Gel with Cobalt-Free Orange Indicator for Desiccators LABKEM
Desiccant silica gel with an orange indicator that shifts to dark green upon moisture absorption. A safer alternative to cobalt chloride-based blue gel.
Why choose this gel over traditional blue
Cobalt chloride—the active indicator in classic blue silica gel—is classified as toxic. This gel uses a cobalt-free orange indicator to signal when regeneration is needed. No changes to existing protocols. No additional hazard classifications.
Absorption capacity
- RH 20% (7 min): ≥ 9.0%
- RH 50% (19 min): ≥ 22.0%
- RH 80% (26 min): ≥ 38.0%
Regeneration and reuse
Dark green coloration indicates saturation. Regenerate in an oven at 100–120 °C for approximately 1 hour. Gel returns to orange and full desiccant capacity.
