Our Manufacturer Specific Fittings Kits are optimal for use with legacy HPLC systems. They are customized for specific manufacturers’ systems. Our numerous kits contain a variety of fittings and accessories that have been selected for use with for the unique needs of each manufacturer specifications still in use today. Some of these are Beckman, Hewlett Packard, Varian and many others.

Our unique tubing cutters allow you to cut polymer tubing to your specific length ensuring burr free ends and providing zero dead volume connections. Our precision cutters for fused silica tubing ensures clean, trouble free cutting of fused silica tubing. We also offer a unique tubing awl to help when you are working with barbed fittings.

Our Polymer Tubing Kits are optimally designed for use in high-pressure applications. Our PEEK tubing kits include our distinct PEEK tubing which is inert to most solvents and give it a smooth internal surface that improves the resolution of sample bands. We have developed a variety of color options for easy coding and identification. Our Tefzel (ETFE) tubing kits provides tubing that is designed with three of the most common inner diameters and its unique material provides low gas permeability.

MicroTight Tubing Sleeves feature an outer diameter of 0.025 inches and offer a wide assortment of inner diameters to help facilitate capillary tubing connections with our MicroTight accessories. Because the sleeves are manufactured from PEEK polymer, they carry an upper temperature threshold of 125 ºC. To use these sleeves properly, choose a sleeve with an inner diameter 0.001 inches – 0.002 inches (25 – 50 μm) larger than the outer diameter of your capillary tubing. Then, slip the sleeve over your flow path tubing, such that your tubing extends all the way through the sleeve, but not beyond the end of the sleeve. Choose the correct fitting that corresponds with your receiving port, slide it over the sleeved flow path tubing and connect as normal.

Our FEP tubing constructed with genuine Teflon™ FEP resin is a great alternative to traditional PTFE tubing, desirable for use because it is chemically inert to most solvents, easy to cut, and translucent for easy monitoring of solutions passing through. It is excellent for general, low pressure applications. We offer many sizes in multiple colors for easy identification. Our tight manufacturing tolerances ensure product consistency.

Our Frit Assemblies come with a specific outer diameter to match the inner diameter of the tube. Their thickness varies from 1/8 to 1/16 inches and they have multiple porosities from 0.5 µm to 20 µm. These assemblies are manufactured from biocompatible PEEK and stainless steel delivering excellent chemical resistance.

Stainless Steel Frit Discs are strong and durable and work easily with most HPLC systems. We offer a wide selection of porosities and sizes for use with many applications. Our durable disc without a polymer ring offers exceptionally uniform porosity and a long filtration life. It comes in a variety of porosities to meet your application needs.

Bulkhead Unions are optimally designed to directly thread through your equipment housing to connect internal tubing to the outside. Each union has unique 3/8-24 external threads and comes complete with a stainless steel nut and lock washer to hold it in place. It requires a 3/8 inches hole to mount. The recommended torque limit for these unions is 15 in.- lbs (1.7 N·m).
