Description
Volumetric flask, brown glass with white graduation, class A, KB, 500 ml, NS 19/26 is a precision measuring vessel made from heat-resistant borosilicate glass 3.3 in accordance with 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 deviations from the nominal volume to a minimum; conformity marking and batch number are printed on the body, and the batch certificate can be downloaded online.
This article is part of Volumetric flasks, in Volumetric glassware.
A diamond-ground meniscus ring mark provides lasting durability and supports clear reading of the meniscus plane. White enamel inscriptions on the brown glass body ensure permanent, high-contrast labelling. Each flask is supplied with a leak-proof PE stopper for a secure seal. This model from manufacturer ISOLAB Laborgeräte is intended for quantitative analytical work where light-sensitive solutions must be prepared or stored under controlled volumetric conditions. The brown glass body helps protect contents from light during routine laboratory use.

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 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.
