Ultra-High Performance Unions

  • Featuring Stainless Steel Bodies and PEEK™ Fittings
  • Pressure Rated up to 15000 psi (1034 bar)
  • Options to Direct-Connect both 1/32" OD Tubing and 360 µm OD Tubing

Upchurch Scientific® has expanded its line of specialized fittings and connectors for UHPLC applications to include several new innovative unions and adapters.

Two of these new products - the UH-432 and UH-436 - follow the design of our popular Mini MicroFilters and allow a convenient union between either 1/32" OD tubing or 360 µm OD tubing. Each features a stainless steel union body and a unique stainless steel union capsule, enabling both excellent chemical compatibility as well as conductivity, making these a great choice for electrical interfacing in certain LC-MS applications. Each is also coupled with direct-connect ferrules made from our proprietary PEEK polymer blend, allowing tubing connections up to 15000 psi (1034 bar).

The other two products are more traditionally designed connectors, incorporating internally threaded ports. Both the adapter (UH-630) and the union (UH-632) feature a true ZDV (zero dead volume) connection between both tubes. Additionally, these unique products are coupled with our one-piece Ultra-High Performance Fingertight fittings manufactured from our proprietary PEEK polymer blend, allowing them to be used in high temperature applications (up to 200ºC) at pressures up to 6000 psi - or use these connectors at room temperature up to 15000 psi (1034 bar).
