Description
Amber volumetric flask, class A and conformity certified, is a precision borosilicate laboratory vessel made from Boro 3.3 glass for accurate preparation and dilution of standard solutions. Designed to DIN EN ISO 1042, it offers a nominal capacity of 100 ml with a ground joint sleeve NS 14/23 and is supplied with a matching NS poly stopper for secure closure. The amber body protects light-sensitive media, while the white inscription ensures clear volume marking and easy identification at the bench. Manufactured by Hecht, this flask supports routine volumetric work in analytical chemistry, quality control and research laboratories where class A tolerances and certified conformity are required. The durable Boro 3.3 construction provides good chemical resistance and thermal stability for everyday use with aqueous and many organic solutions. Supplied as a practical pack of two pieces, the flasks are ready for calibration checks, stock-solution preparation and quantitative transfer steps in regulated and general laboratory environments.

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.
