Description
Volumetric flask 25 ml, class A, is a precision laboratory flask produced from borosilicate glass 3.3 in amber glass for handling light-sensitive liquids. It incorporates a ground joint NS 14/23 closed by a PE stopper and features white Diffico marking for distinct volume indication. Each flask is conformity-certified and provided with a batch number plus a batch certificate accompanying every original packaging, guaranteeing traceability for quality-assured applications. The amber glass construction shields contents from light degradation while class A tolerances support accurate volumetric work such as solution preparation, dilutions and standardisation in chemical, pharmaceutical and research laboratories. Available in packs of 10 pieces from manufacturer Witeg, these flasks unite the thermal and chemical resistance of borosilicate glass 3.3 with dependable PE stopper closure. Well suited to routine analytical tasks requiring certified amber volumetric glassware with documented batch control.

Questions about Volumetric flasks, 25 ml, A, CC, ST 14/23,
What is this article?
Volumetric flasks, 25 ml, A, CC, ST 14/23, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Fioles jaugées, inside Verrerie volumétrique, in Matériel de laboratoire.
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.
