Polytetrafluoroethylene (PTFE) volumetric flask, high and low temperature resistance corrosion resistant, resistant to strong acid, strong alkali, aqua regia, and a variety of organic solvents, and no dissolution, adsorption and precipitation phenomenon).

Use: fixed volume, determine a certain volume, configuration of a certain concentration of the solution.

Note: due to the pure white opacity of the material itself, the liquid level cannot be seen at constant volume. If higher requirements are required for the experimental data, it is recommended to use the volumetric flask made of FEP material.
