Description
Volumetric flask, borosilicate glass 3.3, blue graduated, conformity certified, without stopper is a precision laboratory vessel for accurate volume measurement. This 500 ml flask is manufactured from borosilicate glass 3.3, providing high chemical resistance and thermal stability for routine analytical work. Clear blue graduation markings allow reliable reading of the calibration line during preparation of standard solutions and dilutions. The neck carries an NS 19/26 ground joint and the flask is supplied without a stopper, giving users freedom to choose a suitable closure. Offered as a single piece from manufacturer Hecht, the item meets conformity-certified volumetric tolerances required in quantitative chemistry. Borosilicate glass 3.3 construction supports repeated cleaning and autoclaving cycles common in research and quality-control laboratories. The combination of certified accuracy, durable material and practical joint design makes this volumetric flask well suited for everyday solution preparation and volumetric analysis.

Questions about Volumetric flasks, borosilicate glass 3.3 conformity certified, without stopper
What is this article?
Volumetric flasks, borosilicate glass 3.3 conformity certified, without stopper 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.
