Description

A Stopcock PP/ PTFE is a laboratory device used to control the flow of liquids or gases. It is a type of valve that can be opened or closed to allow or restrict the flow of material.

PP/PTFE stopcocks are made of polypropylene (PP) or polytetrafluoroethylene (PTFE), both of which are common materials used in laboratory equipment due to their chemical resistance and durability.

PP stopcocks are a more cost-effective option, but PTFE stopcocks offer better chemical resistance and are less likely to be damaged by harsh chemicals. The choice between the two materials depends on the specific application and the chemical properties of the materials being handled.
