Description
Volumetric flask, brown glass, white graduation, class A, 200 ml with NS 14/23 joint is a precision measuring vessel manufactured from heat-resistant borosilicate glass 3.3 according to DIN EN ISO 1042. Each unit is calibrated to DIN/ISO class A and bears the DE-M conformity marking of the German weights and measures authority. Individual calibration by automated robots prevents deviations from the nominal volume. Conformity marking and batch number are printed on the flask body; the batch certificate is available for download from the manufacturer website. The diamond-ground meniscus ring mark offers extended durability, and the blue meniscus ring enables easy observation of the meniscus level. White enamel inscriptions are applied to the brown glass body for lasting legibility. Delivered with a leak-proof PE stopper that guarantees a perfect seal, this flask from manufacturer ISOLAB Laborgeräte is ideal for accurate volumetric preparation and storage of light-sensitive reagents and standard solutions. Amber glass protects contents from photochemical change. Pack of 2 pieces supports everyday analytical laboratory use 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 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.
