Description
Overflow volumetric flask 275 ml class B is a specialised laboratory glassware item intended for water examination procedures. The flask is cut at the content mark and features a ground flat cut surface, and it is supplied without a stopper. With a nominal volume of 275 ml and Class B accuracy, it supports reliable volumetric work in analytical settings. This overflow volumetric flask from manufacturer Witeg is suitable for devices from Hach, H&C and WTW, matching several common water-testing instrument platforms. Its open, stopper-free design facilitates overflow measurement techniques used in water analysis laboratories. Originating from Germany (Baden-Württemberg), the flask serves routine water-quality workflows that require Class B volumetric glassware. Laboratories performing aqueous sample preparation and measurement can integrate this 275 ml overflow flask into existing Hach, H&C or WTW-compatible setups with ease. The ground rim and Class B calibration support consistent handling during overflow-based volumetric determinations in environmental testing. This Class B overflow flask provides a practical volume option for specialised water examination protocols.

Questions about Over-flow-flask 275 ml class B
What is this article?
Over-flow-flask 275 ml class B is the article on this page. Luminix Health distributes Witeg 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.
