Description
Overflow volumetric flask 43,5 ml class B is a specialised glassware item developed for precise volume handling during water analysis. The flask is truncated at the content mark, finished with a flat-ground cut surface and supplied without a stopper in accuracy class B. Its 43,5 ml nominal volume is intended for compatibility with WTW instruments used in water examination workflows. Available as a single piece from manufacturer Witeg, this overflow volumetric flask facilitates reliable overflow measurement techniques essential to many analytical water-testing protocols. Net weight of 0,024 kg indicates a robust yet manageable glass construction suited to frequent laboratory handling. The open, stopper-free form simplifies filling, overflow and cleaning steps in high-throughput environments. Class B tolerance delivers the accuracy expected for standard water-quality methods while remaining practical for everyday operations. Environmental laboratories, research institutes and industrial water-testing stations can incorporate the 43,5 ml flask into sample-preparation or titration sequences that rely on overflow volumetric glassware. The plan-ground rim ensures stable placement and clean overflow, supporting reproducible results across successive measurements.

Questions about Over-flow-flask 43,5 ml class B
What is this article?
Over-flow-flask 43,5 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.
