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).

Our MicroTight Unions are designed to easily connect capillary tubing together. They offer True ZDV (Zero Dead Volume) allowing two pieces of tubing to connect directly to each other using the included gauges and plugs to ensure proper alignment. This allows for an uninterrupted fluidic pathway.

Our Stainless Steel Tees and Crosses are precisely designed to withstand environmental stresses in the high pressure regions of a system. Made from durable stainless steel it delivers consistent reliability. They are rated to 20,000psi (1380 bar).

Our robust high-pressure tubing is designed specifically for use in high-pressure and very high-pressure applications such as UHPLC. We offer our tubes in a variety of materials, dimensions and styles to meet your specific applications.
