Threaded Quartz Tubes Description
Threaded quartz tubes with PTFE (Teflon) caps are precision-engineered for laboratory and industrial use where airtight sealing and corrosion resistance are essential.
Each tube is made from high-purity fused quartz, providing outstanding transparency, thermal stability, and chemical durability. The PTFE screw caps ensure secure closure and excellent resistance to aggressive chemicals.
Main Features
素材: High-purity fused quartz body with PTFE threaded caps
Structure: Flat-bottom, closed-end tube with external thread
Temperature Resistance: Quartz tube usable up to 1300 °C; PTFE caps recommended below 200 °C
Chemical Resistance: PTFE provides strong resistance to acids, alkalis, and organic solvents
Precision Fit: Threads are CNC-machined based on cap dimensions to ensure perfect sealing
