Description
Volumetric flask, conformity certified, class A, with NS poly stopper, Boro 3.3 provides a large-capacity option for accurate preparation of bulk standard solutions and other defined liquid volumes. Fabricated from borosilicate glass 3.3, it delivers the chemical resistance and thermal performance required for demanding laboratory handling. This 5000 ml flask is marked with brown inscriptions and produced in accordance with DIN EN ISO 1042, ensuring consistent capacity indication and form. The ground joint sleeve NS 34/35 is closed with the matching NS poly stopper, helping to retain contents securely during mixing and standing. Class A volumetric tolerance and conformity certification support quantitative workflows in research, industrial quality control and teaching laboratories where larger calibrated volumes are needed. The flask from manufacturer Hecht follows standard NS joint sizing, so it pairs readily with compatible stoppers and glassware accessories. Supplied as one piece, it is appropriate for laboratories that require a single high-capacity 5000 ml volumetric flask of this class and joint specification.

Questions about Flask, volumetric class 'A’, clear, amber graduation, with plastic stopper, DIN
What is this article?
Flask, volumetric class 'A’, clear, amber graduation, with plastic stopper, DIN is the article on this page. Luminix Health distributes Hecht 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.
