Shut-Off Valves

  • For Low and Medium Pressure Applications
  • Biocompatible, All-Polymer Flow Path
  • Available for 1/16" and 1/8" OD Tubing
Stop a flow stream quickly with Upchurch Scientific® biocompatible Shut-Off Valves. The bodies are manufactured from either PEEK™ or Tefzel® (ETFE), and both versions feature a Kel-F® rotor, making them highly resistant to chemical attack. The blue colorant used in some valve configurations has proven not to leach out with common HPLC solvents.

Connect semi-rigid or rigid tubing, such as PEEK, stainless steel or fluoropolymer, with the 1/4-28 Flangeless Fittings provided. Soft tubing, such as Pharmed® or Tygon®, may be connected to these valves using our 1/4-28 barbed adapters.

Install a Shut-Off Valve between the solvent reservoir and pump. Then, when it is necessary to disconnect the solvent line, a simple twist of the valve lever eliminates the potential of a hazardous spill.
