Description
Volumetric flask in trapezoidal form made from borosilicate glass 3.3 is a precision laboratory vessel fitted with an NS poly stopper for reliable sealing during volumetric preparation. The trapezoidal body design improves standing stability on the bench while the borosilicate glass 3.3 construction provides the chemical resistance and thermal behaviour required for aqueous and many organic solutions. This conformity-certified flask is intended for accurate dilution and standard-solution work where defined volume and tight closure matter. The NS poly stopper (NS 7/16) seats cleanly in the ground neck, limiting evaporation and contamination between uses. Supplied as a single piece from manufacturer Hecht, the flask suits analytical chemistry, quality-control and teaching laboratories that need compact volumetric glassware. Clear graduation and robust glass walls support repeated handling, washing and autoclave-compatible cleaning routines typical of modern lab practice, while the trapezoidal profile reduces the risk of tipping compared with conventional pear-shaped flasks of similar capacity.

Questions about Volumetric flasks, trapezoidal, borosilicate glass 3.3, with interchangeable
What is this article?
Volumetric flasks, trapezoidal, borosilicate glass 3.3, with interchangeable 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.
