HPLC Tubing

Chrom Tech offers a comprehensive selection of HPLC and UHPLC tubing from IDEX and VICI, engineered for reliable performance in high-pressure chromatography workflows. Our tubing portfolio includes 316 stainless steel, biocompatible PEEK, and fluoropolymer materials such as FEP, ETFE, and PFA—each chosen for chemical resistance, pressure stability, and long-term durability.

Designed to support clean, leak-free flow paths, IDEX and VICI tubing delivers tight OD/ID tolerances and smooth internal surfaces to help maintain chromatographic efficiency and reproducibility. Options are available for aggressive solvents, biological samples, and general low-pressure plumbing, making it easy to match tubing material to your specific application.

Chrom Tech supplies tubing in multiple diameters and lengths to fit a wide range of instruments and system configurations. From fused silica and PEEKsil assemblies to flexible capillaries and precision cutters, we provide everything needed to build and maintain dependable fluidic connections across HPLC and UHPLC platforms.

Chrom Tech is an authorized distributor of IDEX and VICI fluidic components and stocks a broad assortment of HPLC tubing materials ready to ship—helping you keep your systems running with confidence.

Features

Hybrid silica/PEEK design for accuracy and durability
Ultra-smooth bore minimizes band broadening
Ideal alternative to stainless steel or PEEK tubing

Capillaries

Precision-engineered for high-pressure LC flow paths, providing reliable module-to-column connections with laser-welded flat ends to minimize dead volume and protect chromatographic performance.

Features

Laser-welded flat ends reduce dead volume and peak dispersion
Available in stainless steel and bio-inert materials for standard or sensitive workflows
Color-coded by inner diameter for fast, error-free installation

Cutters

Tubing cutters deliver clean, square cuts on stainless steel and polymer tubing to support leak-free connections and minimize dead volume in LC flow paths.
