Highly transparent. Class A tolerances according to DIN EN ISO 1042.The PFA screw cap guards against contamination.Outstanding chemical resistance, can be used with strong oxidants, highly concentrated acids and alkalis, hydrocarbons, and ketones.With laser-engraved lot number and batch certificate. Thermal stress up to 121ºC (autoclaving) does not permanently exceed the tolerance limit.To preserve the ring mark, do not clean at temperatures exceeding 60ºC.The advantages of PFALong-term maintenance of low-concentration reference materials in PFA containersNo memory effectsPractically no carryover, no cross-contamination due to the extremely hydrophobic, anti-adhesive and smooth surfacesHigh thermal stability, from -200°C to +260°CChemical inertness against nearly all chemicalsGood transparency and dimensional stability, suitable for volumetric instrumentsEasy to cleanUse of high purity raw materials
