VWR Silica Gel (TECHNICAL grade, granular form) is a high-capacity desiccant designed for general-purpose moisture control and drying in laboratory, packaging, and industrial applications. Supplied as irregular granules, this non-indicating silica gel provides high surface area and reliable adsorption capacity, even under moderately humid conditions.
Its consistent particle structure and minimal moisture content make it suitable for drying cabinets, reagent storage, compressed air systems, and moisture-sensitive process environments.
Key Features and Benefits
- Technical-grade granular silica gel for moisture adsorption
- Water absorption capacity ≥20% (at 40% RH)
- Low residual moisture: Loss on drying ≤3% at 140 °C
- Thermal and chemical stability under ambient storage conditions
- High boiling and melting points for excellent structural integrity
- Versatile use across laboratory, industrial, and packaging workflows
Applications
- Laboratory desiccation and humidity control
- Drying agents in gas and air filtration systems
- Protection of moisture-sensitive products and reagents
- Desiccant fill for drying tubes, desiccators, and storage vessels
- General-purpose packaging for electronics, optics, or pharmaceuticals
- Humidity stabilization in chemical storage environments
