Description
Volumetric flask, PFA, class A with batch certificate is a precision measuring vessel for accurate laboratory volume determination at a nominal capacity of 250 ml. Fabricated from transparent perfluoroalkoxy alkane (PFA), the flask conforms to DIN EN ISO 1042 and carries DE-M marking that confirms class A accuracy for quantitative analytical work. The GL 25 screw thread accepts the matching screw cap supplied with the unit, giving a reliable seal against evaporation and contamination during solution preparation and short-term holding. Chemically inert PFA resists acids, bases and organic solvents while remaining free from leachables that could affect sensitive samples. This design supports routine preparation of calibration standards, titrants, dilutions and stock solutions in research, pharmaceutical and industrial laboratories. From manufacturer Brand, the flask is supplied as a single unit complete with batch certificate for quality-system documentation and audit trails. The transparent body allows clear meniscus reading, and the robust construction maintains dimensional stability through repeated use under demanding laboratory conditions where reproducibility and chemical compatibility are essential.

Questions about Volumetric flask PFA cl. A, 250 ml, GL 25, with screw cap
What is this article?
Volumetric flask PFA cl. A, 250 ml, GL 25, with screw cap is the article on this page. Luminix Health distributes BRAND for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Matériel de laboratoire.
A volumetric flask is calibrated to contain one volume at a reference temperature, with a single mark on a narrow neck. Class A is the tight tolerance. It is not a storage bottle and it is not for heating. The stopper is part of the calibrated article.
Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
