Description
Trapezoidal volumetric flask class A, 2 ml with NS 7/16 joint, is a precision measuring vessel manufactured from heat-resistant, durable borosilicate glass 3.3 according to DIN EN ISO 1042. The trapezoidal body form delivers significantly improved standing stability and helps prevent accidental tipping on the bench. Calibrated to DIN/ISO class A and bearing the DE-M conformity mark issued by the German weights and measures authority, each flask undergoes individual robotic calibration to keep volume deviations to a minimum. A diamond-ground meniscus ring mark provides lasting resistance and allows straightforward reading of the meniscus level. Blue enamel graduations and lettering are applied to the clear glass body for permanent visibility. Conformity designation and batch number are printed on the flask surface, and the batch certificate is available for download from the manufacturer website. The flask is supplied with a leak-proof PE stopper that ensures a reliable closure. These units from ISOLAB Laborgeräte support accurate volumetric work in analytical, research and quality-control laboratories. Pack size is 2 pieces.

Questions about volumetric flask - trapezoidal - clear - class A - conformity batch certified -
What is this article?
volumetric flask - trapezoidal - 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.
