Glass Beads

Small, spherical glass particles used for polishing, cleaning, reflective surfaces, and in scientific applications like chromatography and bead blasting.

Glass Beads

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)
