Product Specification
| High Light | OD2.9x1x10mm quartz capillary tube ，high temperature resistant capillary tube ，strong acid alkali proof capillary tube | ||
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.
| 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 |
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
