Each flask is supplied with a PE stopper and designed according to ISO 1042 and DIN 12664, calibrated to contain (TC, In). Conformity with metrology requirements is documented by the official “DE-M (year)” symbol printed on every flask, and the batch number is engraved into the glass. A batch certificate is available for free download. Offered as a pack of 2 pieces, these Class A flasks provide the accuracy needed for preparing standard solutions, dilutions and reference materials in analytical and quality-control laboratories. Amber glass shields light-sensitive reagents from photodegradation during volumetric work. With a nominal volume of 20 ml and NS 10/19 ground joint, the flask integrates smoothly into routine workflows. These Premium Line vessels from manufacturer Labbox combine chemical resistance and reliable Class A performance for research, pharmaceutical and industrial laboratories. Net weight is 0,080 kg.

Questions about Volumetric flask amber class A with plastic stopper, 20 ml, mouth size 10/19, Pr
What is this article?
Volumetric flask amber class A with plastic stopper, 20 ml, mouth size 10/19, Pr 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.
