Four fluorine measuring flasks

Teflon (i.e. PTFE, F4) characteristic 　　   Outward appearance pure Baise
　　Thermostable: Application temperature - 200~+250℃;
　　Bears the low temperature: - 196℃ may maintain 5%;
Anti-corrosive: Bears the strong acid, the strong alkali, the aqua regia and each organic solvent;

　Bears the insulation: The dielectric properties with the temperature, the frequency have nothing to do with;

　　High lubrication: In solid state material friction coefficient most bottom;
