Description
Volumetric flask, trapezoidal, conformity certified, class A, with NS poly stopper is designed for precise volumetric work such as standard solution preparation and quantitative dilutions. The vessel is produced from borosilicate glass 3.3, offering robust chemical resistance and good thermal behaviour under typical laboratory conditions. Its trapezoidal shape enhances standing stability on the bench, while blue inscriptions provide clear visibility of the capacity mark and labelling. Built to DIN EN ISO 1042 as a class A flask with conformity certification, it supports accurate analytical, pharmaceutical and research applications. The neck carries an NS 12/21 ground joint and is supplied with a corresponding NS poly stopper for reliable sealing. Nominal content is 50 ml. Available from manufacturer Hecht in a pack of 2 pieces, the flask is practical for laboratories that require multiple calibrated vessels for parallel workflows. Class A performance, stable trapezoidal geometry and durable Boro 3.3 glass together deliver consistent results in routine volumetric procedures.

Questions about Volumetric flask, trapezoidal, clear, class A, blue graduation, with plastic
What is this article?
Volumetric flask, trapezoidal, clear, class A, blue graduation, with plastic 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.
