1. Application
Glass beads are widely used for:
- Laboratory sample drying and desiccation (e.g., in drying ovens and incubators)
- Heat transfer and uniform heating in laboratory baths
- Mixing and agitation in chemical and pharmaceutical labs
- Grinding and polishing in material science applications
- Chromatography, filtration, and packing materials
- Industrial bead blasting and cleaning (high-grade beads)
2. Compliance Standard
- ISO 9001 certified manufacturing
- ASTM E 1246 (for laboratory glass beads, where applicable)
- RoHS / REACH compliant (non-toxic, lead-free)
- Laboratory and industrial grade certifications depending on supplier
3. Product Description
Glass beads are spherical, inert, and chemically stable silica-based spheres, available in various diameters and purity grades. They are heat-resistant and non-porous, making them suitable for precise laboratory and industrial applications.
- Color: Transparent, amber, or white
- Composition: Soda-lime glass or borosilicate glass (high-temperature use)
