Description
Trapezoidal volumetric flask BLAUBRAND® class A is a precision measuring vessel in borosilicate glass 3.3 designed for accurate preparation of volumetric solutions. This 20 ml flask carries blue graduations, DE-M conformity marking and a ground joint NS 10/19, and is supplied with a matching polypropylene (PP) stopper. The trapezoidal body lowers the centre of gravity, giving clear bench stability during filling, mixing and standing. Class A tolerances support quantitative work in analytical chemistry, quality control and routine laboratory assays. Each unit is accompanied by an ISO individual certificate that documents conformity for traceable use. Chemical resistance of Boro 3.3 glass suits aqueous media and many common laboratory solvents, while the durable blue graduation marks remain easy to read under typical lab lighting. Offered as a single piece from manufacturer Brand, the flask integrates smoothly into standard volumetric workflows where reliable volume definition, secure closure and documented accuracy are required day after day.

Questions about Fiole jaugée trapézoïdale BLAUBRAND classe A, 20 ml, avec bouchon PP NS 10/19, DE-M
What is this article?
Fiole jaugée trapézoïdale BLAUBRAND classe A, 20 ml, avec bouchon PP NS 10/19, DE-M 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.
