Borosilicate Glass 3.3 · The Foundation of Quality

All RichTech glassware is manufactured from Borosilicate Glass 3.3 meeting ISO 3585 standards. This material is renowned for its low coefficient of thermal expansion, high thermal shock resistance, and excellent chemical stability — the ideal choice for premium laboratory glassware.

  • Coefficient of Expansion: (3.3 ± 0.1) × 10⁻⁶ / K — ultra-low thermal expansion
  • Thermal Shock Resistance: Withstands rapid temperature changes up to 280°C
  • Chemical Stability: Resistant to water, acids, alkalis, and reagents
  • Light Transmission: >92% visible light transmission for clear observation
  • Softening Point: Approx. 820°C for versatile heating applications

From raw material melting, forming, annealing to finishing — every production step is strictly controlled under ISO 9001 quality management standards to ensure consistent quality and reliable performance.
