Description
Volumetric flask BLAUBRAND® ETERNA Class A is a precision measuring flask in borosilicate glass 3.3 for accurate preparation of standard solutions and quantitative volumetric work. This 10 ml wide-neck version carries brown graduations for clear legibility and is fitted with a ground joint NS 10/19 together with a polypropylene stopper. Class A tolerances and DE-M marking support reliable analytical results, while the accompanying ISO individual certificate documents conformity for each piece. Wide-neck geometry eases filling, mixing and cleaning compared with narrow-neck designs, making the flask practical for routine sample preparation. The BLAUBRAND® ETERNA series from manufacturer Brand is intended for quality-control, research and teaching laboratories that require reproducible Class A glassware. Boro 3.3 construction provides the chemical and thermal resistance expected of laboratory borosilicate glass for aqueous media and many common solvents. Supplied as a single piece, the flask is ready for integration into calibrated volumetric workflows without further modification.

What is this article?
Fiole jaugée, BLAUBRAND-ETERNA, classe A, 10 ml w, avec bouchon PP NS 10/19, cert. is the article on this page. Luminix Health distributes BRAND for laboratory use. It sits in Fioles jaugées, inside Verrerie volumétrique, 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.
