Enhance your HPLC workflow with our complete range of high-quality stainless-steel empty HPLC columns and analytical accessories. Our empty columns — available in 3 mm, 4 mm, and 4.6 mm ID and lengths up to 250 mm — provide a durable and versatile foundation for custom-packed analytical columns.
To support reliable and flexible column assembly, we offer a comprehensive selection of HPLC components including analytical column heads, fitting adapters, zero-dead-volume (ZDV) adapters, coupling nuts, and a wide variety of column end plugs in stainless steel, Delrin, and plastic.
For optimal flow performance and secure filtration, our portfolio includes stainless-steel sieves in multiple pore sizes, glass fiber filters, PTFE sealing gaskets, and complete sieve sets combining sieves, filters, and sealing rings. With this broad accessory range, laboratories can assemble, maintain, and customize analytical HPLC columns with maximum precision, stability, and efficiency.
Protect your analytical HPLC columns and extend their lifetime with our high-quality Guard Columns, available in 3 mm, 4 mm, and 4.6 mm ID. Designed for optimal retention matching and maximum compatibility, these guard cartridges ensure reliable protection against particulates, strongly retained sample components, and matrix impurities.
To provide maximum flexibility, we offer two holder systems: direct-connect guard column heads for seamless, dead-volume-free integration, and stand-alone stainless-steel holders (indirect) for universal use across different column setups. Both systems support guard lengths of 5 mm, 10 mm, and 20 mm and are engineered for robust, leak-free operation.
With precision-machined stainless steel parts and optional PEEK versions for specialized applications, our guard column solutions help maintain peak performance, improve reproducibility, and reduce maintenance costs — making them an essential component in any high-performance HPLC workflow.
Optimize your analytical HPLC setup with our high-performance couplers and tubings designed specifically for 3 mm, 4 mm, and 4.6 mm inner diameter columns. Our portfolio includes precision-machined stainless-steel column couplers, universal PEEK and PEEKsil connectors, and low-dead-volume adapters that ensure secure, leak-free connections and maintain excellent chromatographic performance in analytical workflows.
Engineered for reliability at high pressures, these components deliver stable flow paths, minimal band broadening, and maximum compatibility with all standard 1/16" HPLC systems. Complemented by high-quality stainless-steel tubings in various internal diameters, our solutions provide robust, long-lasting fluidic integrity — ideal for analytical LC applications that demand accuracy, reproducibility, and seamless column-to-column connectivity.
