Questions about Vol. flask BLAUBRAND class A DE-M, 25 ml, Boro 3.3, NS 10/19, PP-stopper
What is this article?
Vol. flask BLAUBRAND class A DE-M, 25 ml, Boro 3.3, NS 10/19, PP-stopper is the article on this page. Luminix Health distributes Brand 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.
