Rotoflo® Glass 2-Way Stopcocks, In-Line Type, Corning®
These high performance Corning® Rotaflo® in-line 2-way stopcocks can be adjusted from a 0 to 6mm bore opening and have 10mm O. D. sidearms. They are designed so that only chemically resistant polytetrafluoroethylene (PTFE) and PYREX® borosilicate glass are in contact with liquids and gases. The Rotaflo® 2-way 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. Serve equally well for gas or liquids at temperatures from 20 to +200°C. Corning 7470 Series.
