Description
Volumetric flask, conformity certified, class A, with NS poly stopper, Boro 3.3 is a precision measuring vessel for accurate preparation and dilution of solutions in the analytical laboratory. Made from borosilicate glass 3.3, it combines chemical resistance with the dimensional stability required for class A volumetric work. The 500 ml nominal capacity is marked with durable blue inscriptions and the neck carries a ground joint NS 19/26, closed by the matching NS poly stopper. Compliance with DIN EN ISO 1042 and the accompanying conformity certificate support traceable volume measurement in quality control, method development and routine wet chemistry. From manufacturer Hecht, this flask is intended for preparing standard solutions, calibration series and reference dilutions where reproducible fill volumes are essential. The poly stopper provides a secure, chemically inert seal during mixing and storage of aqueous and many organic media. Supplied in a pack of 2 pieces, the flasks fit standard laboratory workflows and glassware racks used in research, teaching and industrial analysis. Clear blue graduation and inscription aid rapid identification on the bench.

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.
