Description
Volumetric flask manufactured from borosilicate glass 3.3 and marked with blue graduation serves as a precision vessel for preparing and diluting standard solutions to defined volumes. Conformity certified and delivered without stopper, the 50 ml flask is fitted with a ground joint NS 14/23 that accepts a compatible stopper for closed handling. Borosilicate glass 3.3 delivers strong chemical resistance together with thermal robustness needed in routine analytical chemistry, quality control and research environments. The blue graduation scale remains easy to read under standard lab illumination, supporting consistent volume determination. Supplied as one piece from manufacturer Hecht, this flask is intended for volumetric applications that call for certified conformity. It is well suited to making calibration standards, titrants and stock solutions in pharmaceutical, environmental and educational laboratories. The robust glass construction tolerates customary cleaning cycles used with borosilicate 3.3 ware while preserving measurement reliability over repeated use.

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.
