Medium Pressure Injection Valves

  • Biocompatible and Inert
  • Low Swept Volume
  • Minimal Dispersion

Upchurch Scientific® 6-Port Medium Pressure Injection Valves feature easy, external sample loop customization. Simply clean-cut a piece of tubing that represents the volume of sample you wish to inject, taking into account the port-to-port volume of the valve.

Two biocompatible injection valve options are available:

Long-Life Ceramic

Featuring ceramic-to-ceramic sealing surfaces, these long-life valves have been tested to over one million actuations with no change in performance (Tested using room-temperature water as the solvent). The wetted materials are chemically resistant ceramic and PEEK™ polymer and the valves are rated to 500 psi (34 bar). Each valve includes 1/4-28 Flangeless Fittings for 1/16" OD tubing.

Economical Polymer

These economical valves have chemically resistant Vespel® and PTFE resin wetted surfaces and are rated for a maximum pressure of 1000 psi (69 bar). Each valve includes 1/4-28 Flangeless Fittings for 1/16" or 1/8" OD tubing.

Both valve options are available in three configurations: standard manual, bulkhead mountable manual and actuated.

Please contact Upchurch Scientific for custom configurations for instrument manufacturers. High pressure injection valve options are available.
