Description
Overflow volumetric flask 200 ml class B is a specialised laboratory vessel intended for water analysis. The flask is cut off exactly at the capacity mark, features a plane-ground rim surface and is supplied without a stopper. Class B volumetric accuracy meets the needs of routine water-testing procedures. Designed for compatibility with instruments from Hach, H&C and WTW, it integrates smoothly into established methods for water examination. Produced by manufacturer Witeg, the overflow flask simplifies filling and transfer steps in environmental laboratories, municipal water works and contract testing facilities. Its 200 ml nominal volume offers a convenient working capacity for many standard protocols. The open, flat-ground design allows rapid overflow filling, easy rinsing and straightforward sample handling. Durable glass construction withstands typical laboratory use while maintaining dimensional stability. This flask is particularly useful wherever the overflow volumetric technique is specified for photometric, titrimetric or other water-quality determinations and is supplied as a single piece.

Questions about Over-flow-flask 200 ml class B
What is this article?
Over-flow-flask 200 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.
