Description
Volumetric flask PMP class B 250 ml NS 19/26 with poly stopper is a class B measuring flask made from highly transparent polymethylpentene (PMP) for reliable volumetric work in the laboratory. It offers a nominal volume of 250 ml with an individually adjusted ring mark, supporting accurate preparation of standard solutions, dilutions and quantitative transfers where clear readability of the calibration line is essential. The neck carries a ground joint NS 19/26 and is supplied with a matching NS stopper in polypropylene (PP), giving a secure, easy-to-handle closure during mixing, storage and transport of liquids. Manufactured to DIN EN ISO 1042, the flask meets recognised dimensional and accuracy requirements for class B volumetric glassware alternatives in plastic. The lightweight, break-resistant PMP body from manufacturer Hirschmann combines high transparency with practical chemical resistance for routine analytical and teaching environments. Packaged as 5 pieces, these flasks are well suited to sample preparation workflows, media make-up and general wet-chemistry tasks in which glassware may be less convenient. Clear walls and a precisely set ring mark facilitate confident volume reading under standard laboratory lighting.

Questions about VOLUMETRIC FLASK PMP,B 250 ML, NS 19/26, WITH POLYSTOPPER
What is this article?
VOLUMETRIC FLASK PMP,B 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 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.
