Description
Volumetric flask, conformity certified, class A, with NS poly stopper in Boro 3.3 is a precision glassware item for accurate preparation and measurement of standard solutions. Made from borosilicate glass 3.3 with blue inscription, it is designed to DIN EN ISO 1042 and supplied with a conformity certificate for documented volumetric performance. The 2000 ml nominal capacity and NS 29/32 ground joint sleeve accept a polyethylene stopper that seals the flask during mixing, inversion and short-term holding of solutions. Class A tolerance supports quantitative analytical workflows where volume accuracy is critical, including preparation of calibration standards, dilutions and reference solutions. Thermal and chemical resistance of Boro 3.3 glass suits routine use with aqueous and many organic media in research, quality-control and teaching laboratories. The NS poly stopper is easy to handle and helps limit contamination compared with loose closures. This flask from manufacturer Hecht is offered as a single piece for laboratory stock and method work requiring certified class A volumetric glassware with a defined joint size.

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