Description
Volumetric flask, brown glass with white graduation, class A, KB, 50 ml, NS 12/21 is a precision measuring vessel made from heat-resistant borosilicate glass 3.3 to DIN EN ISO 1042. It is calibrated to DIN/ISO class A and carries the DE-M conformity mark of the German weights and measures authority. Individual robotic calibration keeps each flask close to its nominal volume; the conformity mark and batch number are printed on the body, and the corresponding batch certificate can be downloaded from the manufacturer website.
This article is part of Volumetric flasks, in Volumetric glassware.
A diamond-ground meniscus ring mark provides lasting durability, while the blue meniscus ring allows clear observation of the meniscus plane. White enamel inscriptions on the brown glass body ensure good readability under laboratory lighting. Each flask is supplied with a leak-proof PE stopper for a secure, tight seal. This amber-glass volumetric flask from manufacturer ISOLAB Laborgeräte is intended for accurate preparation and dilution of light-sensitive solutions where class A volumetric performance is required. The 50 ml capacity with NS 12/21 joint suits routine analytical and quality-control workflows. Pack size is 2 pieces.

Questions about volumetric flask - standard - amber - class A - conformity batch certified -
What is this article?
volumetric flask - standard - amber - 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 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.
