Description
Trapezoidal volumetric flask class A, 25 ml, NS 10/19 is a precision measuring vessel manufactured from heat-resistant, durable borosilicate glass 3.3 according to DIN EN ISO 1042. Its trapezoidal body geometry delivers significantly greater standing stability and effectively lowers the risk of accidental tipping during everyday laboratory use. Calibrated to DIN/ISO class A, each flask bears the DE-M conformity marking of the German weights and measures authority. Individual calibration by automated robots prevents deviations from the stated nominal volume. Conformity mark and batch number are printed on the flask body, and the matching batch certificate is available for download from the manufacturer website. The diamond-ground meniscus ring mark offers extended durability and enables straightforward, precise reading of the meniscus. Clear glass bodies carry blue enamel inscriptions that stay clearly visible. Every flask is delivered with a leak-proof PP stopper that ensures a reliable, tight closure. These class A trapezoidal volumetric flasks from manufacturer ISOLAB Laborgeräte support accurate solution preparation and volumetric work in analytical, quality-control and research laboratories. The unit is supplied as a pack of 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 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.
