Description
Volumetric flask 50 ml is a precision measuring vessel made from brown borosilicate glass 3.3 for reliable volumetric determinations in the laboratory. Offering a nominal volume of 50 ml with a single white ring graduation, this class A flask conforms to DIN EN ISO 1042 and provides the accuracy demanded by analytical chemistry. It is fitted with a standard ground joint NS 12/21 and a polyethylene stopper that ensures a tight seal during mixing and temporary storage. Amber glass construction shields light-sensitive contents from photochemical degradation, supporting work with photosensitive compounds. Produced by manufacturer Marienfeld, the flask is well suited to the preparation of standard solutions, dilutions and titrations in pharmaceutical, environmental and research settings. Supplied packed in cartons of 10 pieces, these volumetric flasks combine practical handling with consistent performance for everyday quantitative laboratory applications.

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