A Detachable PTFE Stopcock for a Burette is a laboratory equipment used for the precision dispensing of liquids. A burette is a long, graduated glass or plastic tube with a valve or stopcock for controlling the flow of liquid. The detachable PTFE stopcock is an accessory that can be attached to the burette to control the flow of liquid.

PTFE (Polytetrafluoroethylene) is a type of plastic that has a low coefficient of friction and high chemical resistance, making it ideal for use in laboratory settings. The detachable design of the stopcock allows for easy cleaning and maintenance of the burette.

The combination of the burette and the detachable PTFE stopcock is commonly used in chemical, biological, and pharmaceutical experiments for precise measurement and dispensing of liquids.
