2-Way Polypropylene Stopcock
by United Scientific

With their PTFE plug and polypropylene housing, these stopcocks are leak-proof and featured ribbed ports on either side, allowing them to accommodate two pieces of tubing with an interior diameter ranging from 6-10mm. It can be used as either an on/off valve, or as a flow control: simply turning the handle will regulate how much of the hole drilled into the plug is available for the solution to pass through. Because the plug can be made of extremely rigid materials such as PTFE, it makes them ideal for applications that require high-purity.

Thumbscrew color may vary.
