Desiccators and Desiccant for Moisture-Sensitive Storage
Desiccators and desiccant hold reagents, samples and instruments in a low-humidity environment to prevent moisture uptake, caking and degradation. This category covers desiccator cabinets and bench desiccators plus the silica gel and other desiccant media that maintain the dry atmosphere.
Desiccator and Desiccant Formats Stocked
- Desiccator cabinets - Polycarbonate and acrylic cabinets with one or more compartments, gasketed doors and humidity gauges, in bench and floor sizes for storing moisture-sensitive stock.
- Vacuum desiccators - Bench desiccators with vacuum-rated bodies and stopcock ports for pulling reduced pressure over dried samples, in polycarbonate and glass.
- Auto-purge and gas-purge desiccators - Cabinets with nitrogen or dry-gas purge control that hold a set humidity for sensitive electronics and reagents.
- Indicating silica gel - Color-indicating silica gel that shifts color as it saturates, in packets, canisters and bulk, reusable after oven regeneration.
- Desiccant media and packs - Non-indicating silica gel, molecular sieve and clay desiccant in packets, tins and bulk for drawers, cabinets and shipping.
Desiccator and Desiccant Comparison
| Product | Format | Feature | Typical Use |
|---|---|---|---|
| Desiccator cabinet | Bench, floor | Humidity gauge | Moisture-sensitive stock storage |
| Vacuum desiccator | Bench | Stopcock port | Vacuum drying, low-pressure storage |
| Auto-purge cabinet | Floor | Gas purge control | Electronics, sensitive reagents |
| Indicating silica gel | Packs, bulk | Color change | Visual moisture monitoring |
| Molecular sieve | Beads, packs | High capacity | Deep drying, solvent drying |
Indicating Versus Non-Indicating Desiccant
Indicating desiccant carries a dye that changes color as it absorbs moisture, giving a visual cue that it needs regeneration, which suits open cabinets and monitored storage.
Desiccator cabinets are durable capital items reordered as storage needs grow, while desiccant media is a recurring consumable replaced as it saturates. Order at the best Wholesale Prices with MAP Medical.
Frequently Asked Questions
What is the difference between indicating and non-indicating desiccant?
Indicating desiccant contains a dye that changes color as it absorbs moisture, giving a visual signal that it needs regeneration, which suits open desiccators and monitored cabinets. Non-indicating desiccant has no color change, costs less and is used in sealed packaging where a visual check is not needed. Both are stocked in silica gel, and molecular sieve is available for deeper drying.
Can silica gel desiccant be reused?
Yes. Most silica gel, including indicating grades, is regenerated by heating in a drying oven to drive off absorbed moisture, after which it returns to full capacity and, for indicating types, its dry color. Regeneration temperature and time are listed on the product page. Clay and molecular sieve desiccant are also regenerable under specified conditions.
What is the difference between a vacuum and a standard desiccator?
A standard desiccator maintains a dry atmosphere at ambient pressure using desiccant in a sealed chamber. A vacuum desiccator adds a vacuum-rated body and a stopcock port so a pump can pull reduced pressure, which speeds drying and lowers residual humidity. Vacuum models are stocked in polycarbonate and glass.
Can hospitals and labs order desiccators and desiccant in bulk?
Yes. Desiccators and desiccant are stocked in case quantities for research and QC labs, pharmaceutical and industrial facilities, and clinical labs. Standing orders cover the highest-volume SKUs, including polycarbonate desiccator cabinets, indicating silica gel and bulk desiccant packs. Contact our procurement team for tiered case pricing and standing order setup.
What desiccant and dry-storage should a laboratory stock on its formulary?
A working desiccant and dry-storage stock list typically includes a gasketed desiccator cabinet sized to the stored inventory, a vacuum desiccator for drying, indicating silica gel for monitored storage, and bulk non-indicating desiccant or molecular sieve for sealed and shipping applications.
