Description
Volumetric flask PP, class B 250 ml NS 19/26 with poly stopper is a highly transparent polypropylene flask intended for accurate preparation of fixed volumes in the laboratory. Its 250 ml nominal capacity is indicated by an individually adjusted ring mark and meets class B tolerance requirements according to DIN EN ISO 1042. The NS 19/26 ground joint is closed with the included polypropylene stopper, reducing loss of volatile components and protecting contents from dust. Lightweight PP construction offers good chemical resistance and clear meniscus reading while remaining shatter-resistant compared with glass. This Hirschmann volumetric flask is well suited to preparing buffer solutions, calibration standards and larger sample dilutions in teaching, industrial and quality-control environments. Supplied as a multipack of five pieces, it supports efficient stocking of plastic class B volumetric ware for everyday wet-chemistry applications where glassware is unnecessary or undesirable.

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