Beschrijving
Volumetric flask 50 ml is a class A precision measuring flask designed for reliable volume determination in analytical laboratories. Produced from clear borosilicate glass 3.3, it features one blue ring mark and a standard ground joint NS 12/21 complete with polyethylene stopper. The flask conforms to DIN EN ISO 1042 and delivers the accuracy expected for quantitative sample preparation, dilution and standardisation procedures. These volumetric flasks from manufacturer Marienfeld provide excellent chemical resistance together with good thermal stability, supporting everyday use in chemistry, pharmaceutical and quality-control environments. The clear-glass construction allows easy visual inspection of the contents while the blue graduation ensures clear meniscus reading. Supplied in cartons of 10 pieces, the 50 ml flasks are practical for laboratory inventory and maintain the dimensional and volumetric consistency required by class A specifications for precise analytical work across a wide range of routine applications.

Questions about Volumetric flasks 50 ml,
What is this article?
Volumetric flasks 50 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.
