Description
Volumetric flask in borosilicate glass 3.3, blue graduated and conformity certified, provided without stopper. This laboratory vessel carries a 20 ml nominal capacity together with an NS 10/19 joint, enabling accurate preparation and dilution of solutions in routine analytical work. Clear blue graduation lines afford straightforward volume assessment, while the borosilicate glass 3.3 material delivers the chemical resistance and shape retention required for everyday laboratory use. Without a stopper the neck remains fully open, simplifying filling, mixing and sample withdrawal steps. The flask is produced by Hecht and belongs to the established family of conformity-certified volumetric glassware employed across research, industrial quality control and teaching environments. The 20 ml size offers a practical intermediate volume for medium-scale standard preparation, titrations and calibration procedures where reliable volumetric performance is essential. Conformity certification verifies that the flask satisfies the relevant metrological specifications. Delivered as 1 pc, the item is immediately available for incorporation into laboratory inventories and workflows.

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.
