Volumetric flask, brown glass, white graduation, class A, 100 ml with NS 14/23 joint is a precision measuring vessel manufactured from heat-resistant borosilicate glass 3.3 in accordance with DIN EN ISO 1042. Each flask is calibrated to DIN/ISO class A and carries the DE-M conformity marking of the German weights and measures authority. Individual robotic calibration minimises deviations from the nominal volume. Conformity marking and batch number are printed on the body surface, and the corresponding batch certificate can be downloaded from the manufacturer website. A diamond-ground meniscus ring mark provides long-term durability, while the blue meniscus ring allows clear observation of the meniscus plane. White enamel inscriptions are printed on the brown glass body for permanent readability. Supplied with a leak-proof PE stopper that ensures a secure seal, this flask from manufacturer ISOLAB Laborgeräte is well suited for accurate preparation and storage of light-sensitive standard solutions and reagents. The amber glass protects contents from photochemical degradation during volumetric work. Pack of 2 pieces supports routine analytical laboratory workflows requiring reliable class A glassware.

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 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.
