Volumetric flask, class A, with blue graduation and PP stopper, 10 ml nominal capacity and NS 10/19 joint, is manufactured from heat-resistant borosilicate glass 3.3 in accordance with DIN EN ISO 1042. Calibrated to DIN/ISO class A and bearing the German weights and measures conformity mark (DE-M), each flask is individually calibrated by automated robots to keep deviations from the nominal value to a minimum. Conformity marking and batch number are printed on the body; the corresponding batch certificate can be downloaded from the manufacturer website. The diamond-ground meniscus ring mark offers extended durability, while the blue meniscus ring enables easy observation of the meniscus plane. Inscriptions are applied in blue enamel on clear-glass bodies. These flasks from ISOLAB Laborgeräte are supplied with a leak-proof polypropylene stopper that ensures a reliable seal. Packaged in units of 2 pieces, they support accurate preparation of standard solutions and volumetric dilutions in analytical, research 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.
