Description
Volumetric flask class A, KB, with blue graduation, PP stopper, 100 ml capacity and NS 12/21 joint is a high-precision laboratory vessel for exact volume measurement and solution preparation. Manufactured from heat-resistant borosilicate glass 3.3 in accordance with DIN EN ISO 1042, the flask is calibrated to DIN/ISO class A and carries the German DE-M conformity mark. Individual robotic calibration minimises deviation from the nominal volume; conformity marking and batch number are printed on the body, and the corresponding batch certificate can be downloaded online. A diamond-ground meniscus ring mark ensures long-term durability, while the blue enamel graduation allows clear observation of the meniscus plane on clear glass. The flask is supplied with a leak-proof stopper that provides a reliable seal. This model from manufacturer ISOLAB Laborgeräte is intended for routine analytical chemistry, quality control and volumetric work where class A accuracy is required. Clear glass body with blue markings supports easy reading under standard laboratory lighting. Pack of 2 pieces.

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 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.
