F4 beaker, PTFE beaker, Teflon beaker, acid-resistant alkaline PTFE beaker

This PTFE beaker, also known as an F4 or Teflon beaker, is developed for handling aggressive acids, alkalis, and organic solvents in advanced laboratory and research environments. Manufactured from high-purity polytertrafluoroethylene, it offers exceptional chemical resistance, a wide operating temperature range (typically –200 °C to +260 °C), and a non-stick surface that minimizes sample adhesion and cross-contamination. Available in capacities from 50 ml to 2000 ml, the beaker suits diverse experimental scales, from routine analytical workflows to high-temperature digestion or material synthesis involving corrosive reagents. Its thermal stability and inertness make it particularly relevant for trace-metal analysis, battery electrolyte preparation, and polymer processing where sample integrity is critical. The product supports reproducible results by eliminating leaching and reaction with substrates, ensuring reliable performance in demanding scientific protocols.
