Beschrijving
Volumetric flask, trapezoidal, conformity certified, class A, with NS poly stopper is a precision measuring flask for preparing accurate standard solutions and diluted volumes in analytical chemistry. Made from borosilicate glass 3.3 with blue inscription, it follows DIN EN ISO 1042 and is conformity certified to class A tolerances for reliable volumetric work. The trapezoidal body shape improves stability on the bench compared with conventional round-bottom flasks of very small capacity, while the nominal content of 1 ml supports micro-scale preparations and low-volume standards. A ground joint sleeve NS 7/16 accepts the matching NS polyethylene stopper, helping protect the contents from evaporation and contamination during equilibration or short-term storage. Blue markings remain clearly legible against the clear glass for quick volume identification. These flasks from manufacturer Hecht are well suited to quality-control laboratories, teaching practicals, and research groups that require certified class A glassware for small-volume volumetric tasks. Supplied in packs of 2 pieces, they fit neatly into sets of precision volumetric equipment.

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 Maatkolven, inside Volumetrisch glaswerk, in Labmateriaal.
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.
