Description
Volumetric flask 500 ml is a Class A precision vessel made from brown borosilicate glass 3.3 for accurate preparation and measurement of solutions. It carries a single white ring mark, a standard ground joint NS 19/26 with polyethylene stopper, and is manufactured in accordance with DIN EN ISO 1042. Each flask is conformity-certified and supplied with a batch certificate, supporting documented quality control in analytical laboratories. The amber glass body helps shield light-sensitive media during volumetric work. With a nominal volume of 0,5 l, the flask is well suited to routine solution preparation, standardisation and quality-control procedures that demand Class A tolerance and the chemical durability of borosilicate 3.3. Packed in cartons of ten pieces from manufacturer Marienfeld, the set is practical for stocking shared lab benches or teaching laboratories. The combination of certified accuracy, robust joint finish and light-protective glass makes this volumetric flask a reliable choice for everyday analytical workflows.

Questions about Volumetric flasks 500 ml,
What is this article?
Volumetric flasks 500 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.
