Volumetric flask 5 ml with standard ground joint NS 7/16 and polyethylene stopper is a precision measuring vessel made from clear borosilicate glass 3.3. This class A flask is blue-graduated with a single ring mark and manufactured in accordance with DIN EN ISO 1042. It is conformity-certified and supplied with a batch certificate, supporting reliable volumetric work in analytical and quality-control laboratories. The NS 7/16 joint accepts the matching poly stopper for secure closure during preparation of standard solutions, dilutions and quantitative assays. Clear glass construction allows straightforward meniscus reading at the calibration mark. The flasks are packed in cartons of 10 pieces and originate from manufacturer Marienfeld. Borosilicate glass 3.3 offers good chemical resistance and thermal stability for routine laboratory handling. Nominal volume is 5 ml (0,005 l). These compact volumetric flasks are suited to precise liquid measurement where class A accuracy and certified traceability are required.

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.
