Stopcocks have several outflows: one-way, two-way or three-way and are also available with hose connectors. We stock products of numerous renowned manufacturers, e.g. stopcocks made of PTFE by Bohlender or made of borosilicate glass by Duran.

Duran Stopcocks & Valves

The manufacturer Duran is well-known for high quality lab supply made of borosilicate glass. This extraordinary robust and temperature resistant material is a relevant alternative in the manufacturing of stopcocks. Duran's stopcock range stands out thanks to high manufacturing accuracy and very good ground joint quality. This ensures you have highly effective sealing and interchangeability. For use at higher temperatures stopcocks with glass key are preferable. Stopcocks with PTFE keys enable grease-free working. Alongside standard stopcocks, Duran also offers high-vacuum adapted PRODURAN® valves.
