A burette with a PTFE stopcock is a laboratory instrument used to measure and dispense precise volumes of liquids. It consists of a cylindrical glass or plastic tube with graduations (marks indicating volume) along its length and a stopcock, which is a valve that controls the flow of liquid through the burette.
The stopcock is made of polytetrafluoroethylene (PTFE), a type of plastic that is resistant to chemical attack and offers good stability, making it an ideal material for use in laboratory equipment.
The burette with PTFE stopcock is commonly used in chemical titrations, where it is filled with a solution of known concentration and used to dispense a measured volume of the solution into a reaction flask.
