Description
Volumetric flask class A, KB, blue graduation, PE stopper, 5000 ml, NS 34/35 is manufactured from heat-resistant borosilicate glass 3.3 in accordance with DIN EN ISO 1042 and calibrated to DIN/ISO class A. Each flask receives individual robotic calibration to minimise deviation from the nominal volume and carries the DE-M conformity mark of the German weights and measures authority together with a batch number printed on the body; the corresponding batch certificate can be downloaded from the manufacturer website. A diamond-ground blue meniscus ring mark ensures durable, easy-to-read meniscus observation, while blue enamel inscriptions provide clear permanent labelling on clear glass. The flask is supplied with a leak-proof polyethylene stopper that guarantees reliable closure during mixing and storage. This large-capacity class A volumetric flask from manufacturer ISOLAB Laborgeräte is intended for accurate preparation and dilution of standard solutions in analytical and quality-control laboratories and is offered as a single piece.

Questions about volumetric flask - standard - clear - class A - conformity batch certified -
What is this article?
volumetric flask - standard - clear - class A - conformity batch certified - is the article on this page. Luminix Health distributes ISOLAB 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.
