PTFE funnel

This product is designed for laboratory filtration and sample preparation applications requiring high chemical resistance and thermal stability. Manufactured from polytetrafluoroethylene (PTFE), the funnel series includes both triangular funnels and Buchner funnels in multiple diameter and height configurations, ranging from 30×50 mm to 160×204 mm for triangular types, and from 50 mm to 100 mm for Buchner types. PTFE’s inert nature ensures compatibility with aggressive solvents, strong acids, and bases, making these funnels suitable for use in analytical chemistry, material synthesis, and battery research workflows where contamination must be minimized. The transparent or translucent appearance facilitates visual monitoring of filtration processes. These funnels are typically employed in vacuum-assisted or gravity filtration setups within laboratory environments. The availability of varied dimensions accommodates different sample volumes and vessel sizes, supporting scalable experimental procedures.
