Stainless Steel Tubing

316-series stainless steel HPLC tubing is engineered for ultra-high-pressure chromatography applications, including UHPLC, supercritical fluid chromatography (SFC), and other demanding analytical workflows. Precision manufacturing ensures tight OD/ID tolerances and smooth internal surfaces, supporting reproducible flow paths and consistent chromatographic performance.

Stainless steel tubing offers excellent resistance to corrosion, solvents, and mechanical wear, making it well suited for aggressive mobile phases and long-term laboratory use. These properties help maintain system integrity while minimizing dispersion and dead volume in high-pressure LC systems.

Pre-cut stainless steel tubing provides an economical, ready-to-use solution that eliminates variability from manual cutting. Each length is electrolytically cut, polished, deburred, passivated, and steam-cleaned with micro-filtered deionized water to remove organic and inorganic contaminants, ensuring clean, burr-free ends for reliable zero-dead-volume connections.

Custom-cut stainless steel tubing is also available for applications requiring specific lengths. Tubing under 100 feet is electrolytically cut and steam-cleaned to the same standards as pre-cut tubing. Lengths are specified in inches or feet and rounded up to the nearest foot for pricing. Tubing up to 6 feet is supplied straight, while longer lengths are provided coiled for safe handling and shipment.

For chromatographers with exacting performance requirements, pre-cut and custom-length 316 stainless steel tubing delivers clean finishes, consistent internal geometry, and dependable sealing—helping ensure optimal chromatographic results in modern LC and UHPLC systems.

Key Definitions ▶
OD (Outer Diameter)
The outside measurement of the tubing, used to ensure compatibility with fittings and ferrules.
ID (Inner Diameter)
The internal bore of the tubing that determines flow volume, backpressure, and chromatographic dispersion.
Zero Dead Volume
A connection geometry that minimizes internal void space, reducing band broadening and preserving peak integrity.
Passivation
A surface treatment process that enhances corrosion resistance by forming a protective oxide layer on stainless steel.
Electrolytic Cutting
A precision cutting method that produces flat, burr-free tubing ends while maintaining clean internal surfaces.
Frequently Asked Questions ▶
What applications are stainless steel HPLC tubing best suited for?
Stainless steel tubing is ideal for UHPLC, supercritical fluid chromatography, and other high-pressure analytical workflows where chemical resistance and mechanical strength are required.
Why is electrolytically cut tubing recommended?
Electrolytic cutting produces flat, burr-free ends and smooth internal surfaces, helping achieve zero dead volume connections and consistent chromatographic performance.
Do you offer both precut and custom tubing lengths?
Yes. Chrom Tech supplies precut tubing for immediate use as well as custom lengths cut to your specifications. Tubing under 6 feet is shipped straight, while longer lengths are provided coiled.
How does stainless steel tubing help improve chromatographic results?
Precision OD/ID tolerances, polished internal surfaces, and passivated finishes reduce dead volume and flow disruption, supporting sharper peaks and reproducible separations.
Is stainless steel tubing compatible with aggressive solvents?
Yes. 316-series stainless steel offers excellent resistance to corrosion and chemical attack, making it suitable for demanding mobile phases and long-term laboratory use.
