Combined PTFE and borosilicate glass forms a leak- and freeze-resistant seal
Supplier: PYREX™ 74703
These high performance Rotaflo™ stopcocks can be adjusted. They are designed so that only chemically resistant polytetrafluoroethylene (PTFE) and PYREX™ borosilicate glass are in contact with liquids and gases. The Rotaflo™ stopcock design permits fine flow adjustment. Lubrication is not required and assembly is fast because there are no O-Rings, washers or nuts. The seal is visible when open or closed.
