Rotaflo® PTFE Three-Way Stopcocks
By Corning
These high performance plain bore, three-way stopcocks 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.
