OD2.9x1x10mm High Purity Quartz Capillary Tube Strong Acid Alkali High Temperature Resistance

Product Overview

The High Purity Quartz Capillary Tube (OD2.9mm x Wall 1mm x Length 10mm) is a precision micro-tubing component engineered for chromatography, biochemical analysis, gas detection, and micro-chemistry applications. Manufactured from premium fused silica (SiO2 > 99.99%), it offers exceptional chemical inertness, thermal stability, and optical clarity — with a precision bore and smooth inner wall for low-residue fluid handling.

Key Features

• 1100°C High Temperature Resistance: Maintains structural integrity at extreme temperatures, far surpassing borosilicate glass alternatives
• Strong Acid & Alkali Resistance: Outstanding durability against hydrofluoric acid, strong acids, alkalis, and organic solvents
• High Purity Without Metal Precipitation: SiO2 > 99.99% with ultra-low impurity content, ensuring contamination-free sample handling
• Precision Bore & Smooth Inner Wall: Accurate inner diameter with minimal liquid residue for precise micro-volume transfer
• High Transmittance: Excellent optical clarity for UV-visible detection and monitoring applications

Applications

Competitive Advantages

vs. Borosilicate Glass Capillary: Withstands hydrofluoric acid corrosion; maintains performance up to 1100°C vs ~500°C limit; significantly more accurate bore tolerance; smooth inner wall reduces liquid residue

vs. Stainless Steel Capillary: Superior chemical inertness with no metal ion leaching; transparent wall enables visual flow monitoring; no catalytic interference with sensitive reagents
