Beschrijving
Volumetric flask 20 ml is a Class A precision vessel supplied with conformity certification and individual batch certificate for documented traceability. Made from clear borosilicate glass 3.3, the flask features a single blue ring mark and complies fully with DIN EN ISO 1042. It is equipped with a standard ground joint NS 10/19 and a poly stopper that ensures a tight closure during preparation and temporary storage of solutions. The blue graduation provides high contrast against the transparent glass, facilitating accurate filling to the calibration mark. Excellent chemical resistance and thermal properties of borosilicate glass 3.3 support use with a broad spectrum of laboratory reagents. These certified volumetric flasks from manufacturer Marienfeld are packed ten pieces per carton, ideal for regulated environments that require batch documentation. Typical applications encompass quantitative analysis, preparation of certified reference solutions, and dilution work where both Class A accuracy and batch traceability are mandatory. The combination of precise geometry and certified quality ensures reliable volumetric performance in analytical workflows.

Questions about Volumetric flasks 20 ml,
What is this article?
Volumetric flasks 20 ml, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Maatkolven, inside Volumetrisch glaswerk, 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.
