Description
Volumetric flask, Class A with individual certificate, 500 ml, NS 19/26, Premium Line is a precision laboratory flask intended for accurate volumetric work in analytical chemistry and quality control. It is made from high-quality borosilicate glass 3.3, supplied with a PE stopper, and designed according to ISO 1042, DIN 12664 and the United States Pharmacopeia (USP). The official “DE-M (year)” mark printed on each flask documents conformity with legal metrology requirements. Class A precision manufactured to USP is higher than Class A production to ISO 1042 alone. Calibration is to contain (TC, In). Each flask from manufacturer Labbox has a unique number etched into the glass and comes with an individual calibration certificate showing the actual volume of that vessel. With a nominal volume of 0,5 l and ground joint NS 19/26, the Premium Line design suits standard solutions, dilutions and quantitative transfers. Net weight is 0,335 kg. Borosilicate construction delivers chemical resistance and thermal stability for routine laboratory handling.

Questions about Vol. flask class A w/ plastic stopper, individual certificate, 500ml, mouth size
What is this article?
Vol. flask class A w/ plastic stopper, individual certificate, 500ml, mouth size 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.
