Schlenk Tube, Inner neck, 90° Chem-Cap® Valve

This Schlenk tube has a standard taper inner joint at the top and a 90° 0-4 mm Chem-Cap® valve (0-8 mm on the 250 mL size)  as the sidearm. These are great for storage or for running small reactions.  Counterflow or sampling operations may be conducted by flowing inert gas through the valve inlet and removing the plug.
