Enhance the performance and durability of your large-scale purification workflows with our high-quality hardware for preparative HPLC columns above 10 mm inner diameter. We provide robust stainless-steel components engineered for the demanding conditions of high-flow, high-load preparative chromatography. Our product range includes precision-machined column bodies, high-pressure end fittings, sealing elements, stainless-steel frits, and flow-optimized internal components designed to ensure stable packing, uniform flow distribution, and long-term mechanical integrity in large-ID column formats.
Built for industrial-grade performance, chemical resistance, and reproducibility, our preparative HPLC hardware supports reliable purification of pharmaceuticals, peptides, proteins, polymers, and fine chemicals. With durable construction and compatibility across a wide range of preparative setups, our stainless-steel column hardware delivers maximum robustness, operational safety, and efficiency for any high-throughput LC process.
Protect your preparative HPLC columns with our high-performance Guard Columns and Guard Holders designed specifically for large-ID formats above 10 mm. These rugged stainless-steel guard systems provide an essential first line of defense by removing particulates, matrix impurities, and strongly retained contaminants before they reach the main preparative column. This ensures improved column lifetime, stable performance, and reduced maintenance downtime in high-load purification workflows.
Our guard cartridges for >10 mm ID columns are available in multiple lengths and compatible with a wide range of stationary phases, allowing seamless integration into any preparative LC setup. The robust stand-alone stainless-steel holders feature secure, leak-free sealing and excellent chemical resistance, providing reliable operation even under demanding flow rates and elevated pressure conditions.
Engineered for pharmaceutical purification, biomolecule isolation, polymer fractionation, and large-scale sample clean-up, our preparative guard systems deliver maximum protection, reproducibility, and operational efficiency— making them indispensable for any high-throughput preparative HPLC environment.
Ensure robust, leak-free performance in your preparative HPLC workflows with our high-quality Couplers and Tubings engineered for column formats above 10 mm ID. Designed to withstand the high flow rates, elevated pressures, and demanding solvent conditions typical of large-scale purification, our stainless-steel couplers provide secure, dead-volume-optimized connections between preparative columns, system modules, and accessory components.
Complementing these are our precision-manufactured stainless-steel tubings, available in multiple internal diameters to support stable flow distribution and consistent chromatographic behavior in high-throughput LC environments. Their exceptional mechanical strength, chemical resistance, and dimensional accuracy make them ideal for pharmaceutical purification, biomolecule isolation, polymer fractionation, and other preparative-scale applications.
Built for maximum reliability and long-term operational safety, our preparative couplers and tubings ensure efficient system configurations, reduced downtime, and smooth integration into any large-ID HPLC setup.
Maximize the lifetime and flexibility of your MODCol Spring Columns with our high-precision Repack Kits, available for 25, 30, 50, 70 and 101 mm inner diameters. Each kit is engineered to support fast, reliable column repacking and includes high-quality 2 µm or 5 µm Double Density frits, ensuring excellent bed support, optimal flow distribution, and consistent chromatographic performance.
Our Repack Kits are designed for laboratories requiring full control over their preparative or semi-preparative workflows — whether adapting column selectivity, refreshing worn packings, or optimizing processes for new purification targets. With durable components, seamless handling, and compatibility with all MODCol Spring Column formats, these kits offer an efficient and cost-effective solution for maintaining peak performance in demanding LC applications.
