All SPI Supplies Brand PTFE vials are chemically inert, non-contaminating, and are thermally stable in the range of -200°C (390°F) to + 280°C (+536°F). The vials have a "super smooth" finish making it virtually impossible for anything to "stick" to their surfaces, either inside or outside. The vials are for storage and/or shipping of valuable or aggressive materials and for small scale reactions at low pressure.

Details of the manufacturing:
The SPI Supplies Brand PTFE crucibles are isostatically molded from pure virgin PTFE resulting in a highly inert material, one that will stand up to nearly every way one might want to use them. The thick walled construction with tapered inner wall makes for easy removal of contents.
Cautions about over heating:
PTFE beakers can not be taken to temperatures as high as Pyrex® glass or some other materials. The user has to be sure they do not overheat these PTFE dropping bottles. If PTFE is overheated, especially in air, it can start to break down by both thermal decomposition and oxidation, resulting in fumes of HF which should not be inhaled under any circumstances. The very low extractables from the PTFE used for the construction means that there will be nothing leaching out of the PTFE itself and causing contamination of the contents of the vials.
