Silicon-Coated Stainless Steel Capillary Tube | Seamless H2S Sample Transfer Tubing for Sulfur & Gas Analysis
Low Adsorption Surface– Minimizes H2S and sulfur compound absorption, ensuring accurate trace analysis.
Silicon Coating Technology– 100–250nm silanized layer prevents contamination and preserves gas integrity.
Seamless Stainless Steel Core– 316L / Incoloy 825 tubing with high corrosion and pressure resistance.
Optimized for H₂S Sampling– Ideal for electrochemical or chromatographic trace sulfur detection.
Stable Performance– Rapid recovery from high-concentration samples, ensuring reliable low-concentration detection.
Orbital Weld Ready– Smooth ends for orbital welding and clean gas connections.
Flexible Coiled Form– Reduces fitting use, improves sealing reliability and installation convenience.
Compliant with Industry Standards– Manufactured to ASTM standards.
