VWR PTFE Crucibles

VWR PTFE Crucibles. g. iodine solutions which react with PTFE). Isostatically molded pure FDA approved PTFE crucibles they may be used in temperatures up to 270C (518F). The precision-tooled polytetrafluoroethylene (PTFE) material which they are made of is chemically resistant and inert. They may be used in organic solvents and organic solvent vapor phase reactions where they prevent sample etching and sample loss. The FL series crucibles have a wide selection of volume capacities and a number o
