Description
Volumetric flask, class A, 50 ml with NS 12/21 ground joint is a precision laboratory vessel for accurate volumetric preparation and quantitative analysis. Made from high-quality borosilicate glass 3.3 and fitted with a PE stopper, this Premium Line flask is designed in accordance with ISO 1042, DIN 12664, the United States Pharmacopeia (USP) and the German calibration ordinance. Conformity with the calibration ordinance is documented by the official “DE-M (year)” symbol printed on every flask. Class A precision manufactured to USP is higher than that obtained under ISO 1042 alone. The vessel is adjusted to contain (TC, In). A batch number is etched into the glass of each flask, and a batch certificate is available as a free download. Nominal volume is 50 ml (0,05 l) with a net weight of 0,125 kg. Supplied as a pack of two pieces from manufacturer Labbox, these flasks are suited to analytical chemistry, pharmaceutical quality control and routine preparation of standard solutions where USP-compliant class A accuracy is required.

Questions about Volumetric flask class A with plastic stopper, 50 ml, mouth size 12/21, USP Prem
What is this article?
Volumetric flask class A with plastic stopper, 50 ml, mouth size 12/21, USP Prem is the article on this page. Luminix Health distributes Labbox 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.
