Stopcock Parts and Components
Stopcock parts and components give stopcocks a wider range of uses. Stopcock plug assemblies are also produced to replace parts in existing lab equipment. Plastic replacement stopcock parts and components, when paired with a stopcock, are often used in conjunction with separatory funnels, Schlenk flasks and burettes.
