Beschrijving
Volumetric flask, trapezoidal, borosilicate glass 3.3, with NS poly stopper is a precision laboratory vessel intended for accurate preparation and measurement of defined liquid volumes. Manufactured from high-quality borosilicate glass 3.3, the flask combines excellent chemical resistance with thermal stability suited to routine analytical work. The distinctive trapezoidal body provides a stable base and clear visibility of the meniscus, while the NS poly stopper ensures a reliable seal at the ground joint NS 7/16. This conformity-certified 5 ml model supports reproducible volumetric operations such as standard solution preparation, dilution series and quantitative analysis in research, quality-control and teaching laboratories. Supplied as a single piece from manufacturer Hecht, the flask integrates smoothly into existing glassware sets and meets the practical demands of daily laboratory use where dimensional accuracy and material durability are essential. The robust construction withstands repeated cleaning cycles and common laboratory reagents without compromising calibration integrity.

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 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.
