Description
Amber volumetric flask, conformity certified, class A, with NS poly stopper is a precision laboratory measuring vessel made from borosilicate glass 3.3. Featuring a nominal content of 25 ml and an NS 10/19 sleeve joint, it supports accurate volumetric preparation in accordance with DIN EN ISO 1042. Durable white inscriptions give clear volume indication on the amber body, which helps limit light exposure for photosensitive reagents and standards during dilution and storage. The matching polyethylene stopper seats securely in the ground joint for reliable closure. Supplied in a pack of 2 pieces from manufacturer Hecht, these class A flasks are suited to analytical chemistry, quality control, pharmaceutical work and environmental testing where certified volume accuracy and light protection are required. Borosilicate 3.3 provides the chemical resistance and thermal behaviour expected of everyday laboratory glassware for stock solutions, standardisation and quantitative workflows.

Questions about Flask, volumetric class 'A’, amber, white graduation, with plastic stopper, DIN
What is this article?
Flask, volumetric class 'A’, amber, white 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.
