PTFE Labwares

Stopcocks

PTFE Stopcocks are used in a variety of laboratory applications. The inert nature of PTFE makes it ideal for use as a stopcock in applications involving corrosive chemicals, while its durability and machine-ability make it a very convenient alternative to conventional glass stopcocks.

With our team to CNC programmers and machinists, Poly Fluoro is able to make customised components requiring specific taper dimensions and close tolerances. For standard sizes, kindly contact us and quote as per the chart given below.
