What is a Fused Quartz Tube?
A fused quartz tube is a high-purity silica-based (SiO₂ ≥99.98%, max. up to 99.995%) cylindrical component engineered to withstand extreme temperatures (≤1450°C), corrosive environments, and rapid thermal shifts.
It combine ultra-low thermal expansion, chemical inertness, and optical clarity for lab, industrial, and optical applications.
Key Properties of Fused Quartz Glass Tubes
Ultra-High Temperature Resilience
These quartz glass tubes have a melting point of approximately 1730°C, can operate continuously at 1100°C (2012°F), and withstand short-term temperature bursts of 1450°C (2642°F).
Their low coefficient of thermal expansion (5.5×10⁻⁷/°C) ensures excellent durability even under rapid temperature changes.
Superior Material Purity
With silica purity exceeding 99.98%(max. up to 99.995%), TOQUARTZ fused quartz glass tubes minimize contamination in precision optics, and sensitive lab environments, while this high-purity structure creates uniform molecular alignment that significantly enhances quartz tube pressure rating.
