Beschrijving
Trapezoidal volumetric flask class A, 1 ml, is a precision measuring vessel manufactured from heat-resistant, durable borosilicate glass 3.3 in accordance with DIN EN ISO 1042. The distinctive trapezoidal body geometry provides markedly higher standing stability and substantially reduces the risk of tipping during routine laboratory handling. Each flask is calibrated to DIN/ISO class A and carries the DE-M conformity mark of the German weights and measures authority. Individual robotic calibration minimises deviation from the nominal volume. A diamond-ground meniscus ring mark ensures long-term durability and clear observation of the meniscus plane, while blue enamel graduations and inscriptions remain permanently legible on the clear glass body. Conformity marking and batch number are printed directly on the flask surface; the corresponding batch certificate can be downloaded from the manufacturer website. Supplied complete with a leak-proof PE stopper that guarantees a secure seal, these flasks from ISOLAB Laborgeräte are well suited for accurate volumetric preparation and dilution work in analytical 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 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.
