The Corning® Rotaflo® high performance three-way stopcock can be adjusted from a 0 to 3mm bore opening and has 8mm outer diameter sidearms. It is 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.
