Beschrijving
Volumetric flask, PMP, class A, with NS stopper 10/19, PP, 25 ml is a precision laboratory vessel for accurate preparation and dilution of standard solutions and reagents. The flask body is made of polymethylpentene (PMP), offering chemical resistance and high transparency for clear meniscus reading during volumetric work. It meets accuracy class A and features a ground joint NS 10/19 closed with a polypropylene (PP) stopper, providing a secure seal for mixing, standing and short-term holding of prepared liquids. The nominal volume is 25 ml (0,025 l), a practical size for analytical chemistry, quality-control workflows and teaching laboratories that handle small-volume standards. Supplied as a single piece with a gross weight of 0,022 kg, this volumetric flask from manufacturer Vitlab supports reproducible measurements in research and industrial environments. Class A tolerance together with the NS stopper helps limit evaporation losses and contamination risk during sample preparation. Suitable for aqueous solutions and many organic media compatible with PMP and PP, it is a reliable choice for everyday volumetric tasks at the bench.

Questions about Volumetric flask, PMP, class A, 25 ml, with stopper, NS 10/19, with ring-mark,
What is this article?
Volumetric flask, PMP, class A, 25 ml, with stopper, NS 10/19, with ring-mark, is the article on this page. Luminix Health distributes Vitlab for laboratory use. It sits in Maatkolven, inside Volumetrisch glaswerk, in Labmateriaal.
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.
