Precision Stainless Steel 304 316L Capillary Tube For Chromatographic Instrument
Overview:
A precision capillary tube is a hollow cylinder with an extremely small, tightly controlled inner diameter, which is manufactured from austenitic stainless steel grades 304 or 316L. For chromatography, these stainless steel capillary tubes are characterized by ultra-smooth internal surfaces, tight dimensional accuracy, high cleanliness, and corrosion resistance. They function as conduits for fluids, like mobile phase, samples, reagents, under pressure within HPLC, IC, GC, and other chromatographic systems. Stainless steel 316L is the preferred grade for most chromatography due to superior corrosion resistance, especially against chlorides. Our provided capillary tubes are also used in other industries, like precision instruments, medical equipments, electronic equipments, and so on.
Key Features:
Ultra-Smooth Internal Surface: Achieved via precision drawing and Polishing. Minimizes turbulence, adsorption, carryover.
High Corrosion Resistance (Especially 316L): Resists acids, bases, salts, and organic solvents common in mobile phases.
Dimensional Precision & Consistency: Ensures reproducible flow paths and system performance.
High Cleanliness: Manufactured and packaged in controlled environments to prevent particulate or organic contamination.
Mechanical Strength & Rigidity: Maintains shape under pressure and during installation.
Key Applications in Chromatography:
High-Performance Liquid Chromatography (HPLC/UHPLC): Connecting tubing between injector, column, and detector.
Ion Chromatography (IC)
Gas Chromatography (GC): Transfer lines (e.g., from injector to column, column to detector), especially for heated zones; carrier gas lines; parts of valves.
Sample Introduction Systems: Nebulizer capillaries; autosampler needle seats and capillaries.
Reagent & Solvent Delivery Lines.
Waste Lines.
Manifold Plumbing.
