Description

PTFE (Teflon) Mixing Plugs, Laboratory Grade – China (MP-01 to MP-05)

PTFE mixing plugs are essential laboratory accessories used to seal standard ground glass joints in flasks, bottles, condensers, and other laboratory glassware assemblies. Manufactured from high-purity PTFE (Polytetrafluoroethylene), these plugs offer near-universal chemical resistance, making them suitable for use with virtually all laboratory solvents, acids, and alkalis without degradation or contamination risk.

Unlike glass stoppers, PTFE plugs do not seize or bond to glass joints even after prolonged contact with aggressive chemicals or repeated heating cycles. This makes them significantly easier to remove and reuse, reducing breakage risk and improving laboratory efficiency. The smooth surface finish ensures a snug, leak-resistant fit within compatible joints while remaining easy to insert and remove by hand.

Their high temperature resistance makes them suitable for use in heating assemblies, reflux setups, and autoclaving where conventional rubber or plastic stoppers would degrade. Each size is designated by a standard joint number corresponding to the inner diameter of the compatible ground glass joint, ensuring straightforward selection for any laboratory glassware setup.

Widely used in chemical synthesis, distillation, analytical chemistry, and general laboratory glassware assemblies wherever a chemically inert, reliable, and reusable sealing solution is required.
