Stopcocks, Valves

Here you find stopcocks and valves in several forms and with diverse characteristics: We offer e. g. clearance valves or one-way-valves as well as high vacuum or PTFE valves. Due to their fine thread, high vacuum valves are suitable for exact dosing. PTFE valves enable greaseless analyses. 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.

Here you find further information on 2- and 3-Way-Stopcocks.

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.
