Description
Volumetric flask, conformity certified, class A, with NS poly stopper, Boro 3.3 is a precision measuring flask for accurate preparation of standard and sample solutions. Made from Boro 3.3 glass, it carries blue inscriptions and is conformity certified to DIN EN ISO 1042 in accuracy class A. Nominal capacity is 25 ml with ground joint NS 10/19 closed by an NS poly stopper. Pack size is 2 pc(s). This volumetric flask from manufacturer Hecht supports quantitative analytical work where class A volumetric glassware is required. Blue markings remain clearly visible on the glass body, indicating capacity and classification. Certified class A accuracy, DIN EN ISO 1042 compliance, Boro 3.3 construction and the NS poly stopper enable reliable dilution and standard preparation. The NS 10/19 joint matches common stoppers for this range. Such conformity-certified class A flasks are chosen for titration, calibration and reference solution workflows that demand reproducible volume definition. The 25 ml size suits smaller working volumes while retaining class A performance under the stated standard.

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.
