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
| Industry | Application |
|---|
| Chromatography | HPLC and GC flow restrictor tube for trace sample delivery, precise
micro-flow control |
| Biochemical Instrument | Micro pipette tubing for quantitative reagent transfer in automated
analyzers |
| Industrial Gas Monitoring | Gas split capillary for tiny flow control and corrosive process gas
sampling |
| Lab Micro-Chemistry | Delivery tube for HF and other aggressive chemicals in
micro-reaction setups |
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
