The features of our Stopcocks

With stopcocks for high vacuum work through to stopcocks suitable for general use, the SciLabware range contains stopcocks for most applications. The Rotaflo®High Performance stopcocks feature a PTFE needle valve and can operate over a pressure range +1bar to 10-9 Torr. The Rotaflo® General Purpose stopcocks are more suitable for general use and feature the same PTFE needle valve that is used on a range of Pyrex®, MBL®and Quickfit® laboratory glassware products. Pyrex® branded stopcocks are available with both glass and PTFE stopcock keys. All Rotaflo® and Pyrex® stopcocks are available in different designs including straight pattern, right angle and three-way. We also offer stopcocks assemblies to repair burettes and separating/dropping funnels.
