Description
Overflow volumetric flask 365,0 ml class B is specialised laboratory glassware intended for water investigation and analysis. The flask is cut at the content mark with flat-ground cut surfaces and is supplied without a stopper, conforming to class B accuracy requirements. Its nominal volume of 365,0 ml makes it suitable for use with WTW instruments in water-testing workflows. The overflow design supports reliable filling to the mark for volumetric preparations and sample handling in environmental and water-quality laboratories. This overflow volumetric flask from manufacturer Witeg provides a practical tool for routine analytical tasks where class B precision is appropriate. Flat-ground rim surfaces facilitate clean handling and consistent performance during repeated use. With a net weight of 0,114 kg the unit remains lightweight and easy to manage on the bench. It is well suited to laboratories performing water examination that require instrument-compatible overflow flasks for dilution, standard preparation or related volumetric work under class B tolerances.

Questions about Over-flow-flask 365,0 ml class B
What is this article?
Over-flow-flask 365,0 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.
