Right-Angle Cone to Flexible Tubing Rotaflow Stopcock Adapter, 19/26 Cone, Borosilicate Glass

This Eisco Labs Stopcock Adapter features a cone/flexible tubing connection with a right-angle configuration and a Rotaflow key. The cone size is 19/26, providing compatibility with standard ground glass joints. The right-angle design redirects flow 90° between ground glass apparatus and flexible tubing, making it useful for connecting glassware to vacuum lines, gas supplies, or drainage tubing. The Rotaflow key provides smooth, one-handed flow control. Suitable for distillation, vacuum filtration, and other laboratory setups.
