Quartz Glass Tubes
Quartz glass tubes are made of fused silica, a type of quartz crystal. They are highly transparent, heat-resistant, and chemically inert .
Quartz glass tubes are valued for their exceptional purity and ability to withstand high temperatures and corrosive environments, making them ideal for use in harsh conditions.

Key Features & Advantages
Exceptional Thermal Stability: Withstands extreme temperature fluctuations (up to 1100°C - 1200°C) without deformation. Softening point reaches approximately 1730°C.
High Optical Purity: Offers over 90% light transmittance across the UV to IR spectrum (200nm to 2500nm), making it perfect for UV sterilization lamps and optical devices.
Superior Chemical Resistance: Inert to most acids (except hydrofluoric acid and hot phosphoric acid) and alkalis, ensuring longevity in corrosive chemical environments.
Low Thermal Expansion Coefficient: Exhibits extremely low expansion (α ≤ 5.4 x 10⁻⁷ /°C), providing excellent thermal shock resistance (can be heated to 1000°C and plunged into cold water without cracking).
High Electrical Insulation: Outstanding dielectric strength and volume resistivity, suitable for high-voltage applications.
