Volumetric flask, class A, KB, blue graduation, PP stopper, 25 ml, NS 12/21 is manufactured from heat-resistant borosilicate glass 3.3 in accordance with DIN EN ISO 1042 and calibrated to DIN/ISO class A. Individual robotic calibration minimises deviation from the nominal volume. Each flask carries a 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 meniscus ring mark provides long-term durability, while the blue ring facilitates clear observation of the meniscus plane. Inscriptions are applied in blue enamel on clear glass. The flask is supplied with a leak-proof PP stopper that ensures a secure closure. Offered as a pack of 2 pieces from manufacturer ISOLAB Laborgeräte, this 25 ml vessel with NS 12/21 joint is suited to precise volumetric preparation and dilution work in routine and quality-control laboratories.

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 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.
