Product Description

The Stopcock PTFE is a high-quality laboratory component designed for superior liquid and gas handling in laboratory glassware and distillation setups. Featuring a precision-ground glass or steel ball combined with a PTFE (Polytetrafluoroethylene) valve, this stopcock offers excellent chemical resistance, thermal stability, and long-term durability, making it ideal for demanding laboratory environments.

Its precision-machined taper provides a leak-proof fit and vacuum-tight seal when used with compatible laboratory glassware. These PTFE stopcocks are widely used in distillation assemblies, separating funnels, dropping funnels, vacuum manifolds, vacuum lines, condensers, filtration assemblies, and burettes. The non-stick, chemically inert properties of PTFE make it the perfect choice for chemically aggressive laboratory environments.
