Description
Volumetric flask 25 ml is a Class A measuring vessel designed for precise volumetric work in analytical and quality-control laboratories. Constructed from clear borosilicate glass 3.3, it carries one blue ring mark and meets the requirements of DIN EN ISO 1042. The flask incorporates a standard ground joint NS 10/19 together with a poly stopper for secure sealing. Blue graduation on the transparent body ensures easy reading of the calibration line during filling. The inherent chemical resistance and thermal stability of borosilicate glass 3.3 allow safe handling of many aqueous and organic solutions. These volumetric flasks from manufacturer Marienfeld are supplied in cartons of 10 pieces, providing practical packaging for everyday laboratory stock. Common applications include preparation of standard solutions, quantitative dilutions, and titration procedures that demand Class A accuracy. The robust design maintains volumetric integrity over repeated use while offering clear visibility of the single ring mark for reproducible results.

Questions about Volumetric flasks 25 ml,
What is this article?
Volumetric flasks 25 ml, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Matériel de laboratoire.
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.
