Laboratory Stopcock Flow Control Valve for Glassware

The Laboratory Stopcock is a manually operated valve designed to control, regulate or stop the flow of liquids or gases through compatible laboratory glassware and apparatus. A typical stopcock consists of a valve body with a rotating plug or key containing an internal passage. Turning the plug aligns or closes the passage, allowing the user to control flow through the connected laboratory apparatus. Stopcocks are commonly incorporated into or used with burettes, separatory funnels, addition funnels and other laboratory glassware requiring controlled dispensing or flow isolation. Depending on the specific product, the stopcock may be made from glass, PTFE or a combination of glass and PTFE components. The exact type should be matched to the intended laboratory apparatus.
