Beschrijving
Volumetric flask 5 ml is a class A precision laboratory flask intended for accurate preparation and measurement of liquid volumes in analytical chemistry. Produced from borosilicate glass 3.3 as brown glass, the vessel provides chemical resistance together with light protection for sensitive solutions. It has a nominal volume of 5 ml, is white graduated and carries one ring mark in accordance with DIN EN ISO 1042. The flask is fitted with a standard ground joint NS 7/16 and supplied with a poly stopper for secure closure during mixing and storage. These measuring flasks from manufacturer Marienfeld are packed in cartons of 10 pieces, supporting convenient stocking in research, quality-control and teaching laboratories. The brown glass body helps shield contents from light while the class A tolerance ensures reliable volumetric performance for standard solutions, dilutions and quantitative work. Suitable for routine laboratory applications that require both volumetric accuracy and protection of light-sensitive media under controlled conditions.

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.
