Volumetric flask with a nominal volume of 5 ml, Class A accuracy, standard ground joint NS 7/16 and polyethylene stopper constitutes essential precision glassware for analytical laboratories. Fabricated from clear borosilicate glass 3.3, the flask features blue graduation markings and a single ring mark for exact volume determination conforming to DIN EN ISO 1042. Class A certification guarantees the tight volumetric tolerances demanded by quantitative chemistry, standard solution preparation and precise dilutions. The ground joint accepts the included poly stopper, ensuring a secure seal that prevents evaporation or contamination during shaking and temporary storage. Offered by manufacturer Marienfeld and packed ten pieces per carton, the set supports efficient replenishment of laboratory stocks. Borosilicate glass 3.3 delivers outstanding resistance to thermal shock and chemical attack, allowing safe use with many reagents under standard conditions. Transparent walls enable clear observation of the liquid meniscus for reproducible filling to the calibration mark. This compact 5 ml volumetric flask is well suited to educational settings, research facilities and industrial quality-control laboratories requiring dependable small-volume measurements.

Questions about Volumetric flasks 5 ml,
What is this article?
Volumetric flasks 5 ml, is the article on this page. Luminix Health distributes Marienfeld 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.
