Description
Volumetric flask PMP, class A, 250 ml NS 19/26 with poly stopper is a highly transparent polymethylpentene laboratory flask for precise larger-volume preparations. The class A ring mark is individually adjusted to support accurate dilution and standard-solution work at the 250 ml level. Made from PMP, the vessel delivers high clarity for confident meniscus reading together with practical plasticware durability. It comes with an NS stopper manufactured from polypropylene and meets the requirements of DIN EN ISO 1042. This 250 ml model from manufacturer Hirschmann is appropriate for analytical workflows, sample preparation and routine quantitative applications in research, industrial and educational laboratories. The NS 19/26 ground joint pairs with the poly stopper to close the flask securely during mixing or short-term holding of prepared media. Lightweight PMP construction simplifies handling compared with equivalent glass flasks while retaining class A volumetric intent. High transparency of the body aids clear observation of the calibration mark. The flasks are supplied in a pack of five pieces for straightforward laboratory stocking and replacement of calibrated PMP volumetric ware.

Questions about VOL. FLASK PMP, A, 250 ML, NS 19/26, WITH POLYSTOPPER
What is this article?
VOL. FLASK PMP, A, 250 ML, NS 19/26, WITH POLYSTOPPER is the article on this page. Luminix Health distributes Hirschmann for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Labware.
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.
