Description
Volumetric flask, amber glass, LBG 3.3, Class A, with plastic stopper, 1000 ml, is a large-capacity precision vessel made from borosilicate glass 3.3 for accurate volumetric preparation. The amber brown glass protects light-sensitive media, and the PE plastic stopper provides a reliable seal. Designed in line with ISO 1042 and DIN 12664 and calibrated to contain (TC, In), this Class A flask is suited to preparing bulk standard solutions, stock dilutions and analytical reagents where high volumetric confidence is required. Nominal volume is 1000 ml with ground joint size 24/29, fitting quantitative chemistry, quality-control and pharmaceutical laboratory applications. Supplied as a pack of 2 pieces from manufacturer Labbox, each unit has a net weight of 0,800 kg. A batch certificate is available via free download to support batch documentation. Combining LBG 3.3 borosilicate construction, amber colouration and a polyethylene closure, the flask offers durable light protection and Class A performance for laboratories handling larger volumetric batches on a routine basis.

Questions about Volumetric flask, amber glass LBG 3.3, class A with plastic stopper, 1000 ml, 24
What is this article?
Volumetric flask, amber glass LBG 3.3, class A with plastic stopper, 1000 ml, 24 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.
