Volumetric flasks, PFA, Class A, with screw cap Class A tolerances in accordance with DIN EN ISO 1042. The PFA screw cap protects against contamination. Excellent chemical resistance, can be used with strong oxidizing agents, highly concentrated acids and alkalis, hydrocarbons and ketones. With lasered lot number and batch certificate. Thermal loads up to 121 ° C. (Autoclaving) do not permanently exceed the tolerance limit. To protect the ring mark, cleaning up to max. 60 ° C recommended. The advantages of the PFA: long shelf life of low-concentration reference material in PFA vessels, no memory effects, practically no carry-over, no cross-contamination due to the extremely hydrophobic, anti-adhesive and smooth surfaces, high thermal stability from -200 ° C to +260 ° C , chemically inert to almost all chemicals, good transparency and dimensional stability - therefore also suitable for volumetric instruments, easy to clean and high degree of purity of the starting material.
