The advantages of PFA
-Long-term maintenance of low-concentration reference materials in PFA containers
-No memory effects
-Practically no carryover, no cross-contamination due to the extremely hydrophobic, anti-adhesive and smooth surfaces
-High thermal stability, from -200°C to +260°C
-Chemical inertness against nearly all chemicals
-Good transparency and dimensional stability, suitable for volumetric instruments
-Easy to clean
-Use of high purity raw materials
