VHP MicroTight® Unions feature a durably crafted stainless steel bodies, unique stainless steel union capsule and biocompatible PK/PEEK fittings. This enables excellent chemical compatibility and conductivity making it an ideal choice for electrical interfacing in certain LC-MS applications. It delivers zero dead volume allowing two pieces of tubing to perfectly butt together. It has a pressure rated up to 15,000 psi (1,034 bar). Our unions offer the option to direct-connect both 1/32 inches outer diameter tubing and 360 μm outer diameter tubing.

RheBuild® Kits offer an easy and cost effective way to maintain most of our valve products. Included in each individualized RheBuild Kit are all the parts, tools, and instructions to maintain the precision performance of our valve platforms. RheBuild Kits are convenient and eliminate the need to order individual parts separately.

Back Pressure Regulators are designed to enhance system performance through outgassing prevention and improved pump check valve efficiency. It includes 5 and 20psi assemblies (replacement cartridges not available), a variety of pressure rated cartridges and assemblies, PEEK and stainless steel BPR holders, high pressure adjustable BPR for pressure between 2000 and 5000psi and ultra-low volume BPRs set to 100 and 500psi.

Our Stand Alone Valve Products offer more sophisticated functionality. Versatile, they can be added to your existing instrument or in stand-alone lab configurations. Choose an automated valve if the application requires fast, consistent sample injection or flow-stream switching. Some other advantages of automated valves include control options (PC- or instrument-triggered), higher pressure operation, valve-position feedback, or very small flow paths. Note: For Valves please allow an additional 8 days lead time.

Our reusable VHP Fittings are capable of up to ten repeat assembly cycles with no impact on pressure holding ability or carry-over. They are pressure rated up to 25000psi making them ideal for UHPLC applications. They are designed for the most commonly used ports in UHPLC that being 10-32 threads for 1/16 inches outer diameter tubing and M4 threads for 1/32 inches outer diameter. They are manufactured from stainless steel and proprietary PEEK polymer blend (PK) ensuring strength and chemical compatibility.

Kinesis provides innovative solutions to the most demanding low and high pressure fluid path applications, HPLC and UHPLC as well as low pressure chromatography within the laboratory and the OEM environment. A comprehensive range of low and high pressure fittings from Upchurch Scientific and Diba Industries combined with adapters, valves and flow path accessories and a variety of tubing and capillaries allows the scientist to develop almost any fluid path imaginable.

With the industry’s most complete selection of standard accessories, chances are we already have a holder that will fit your product. If not, we can build one for you, exactly tailored to your requirements.
