Description
Overflow volumetric flask 700 ml class B is a specialised laboratory glassware item intended for water analysis. The flask is cut off at the content mark, features a plane-ground cut surface and is supplied without a stopper. This class B volumetric flask offers a nominal capacity of 700 ml and is suitable for instruments from Hach, H&C and WTW. Produced by manufacturer Witeg, it supports precise volumetric work in environmental testing, water quality control and related analytical procedures. The overflow design allows convenient filling exactly to the calibration mark, making it practical for routine laboratory use where class B accuracy is sufficient. Clear visibility of the meniscus aids reliable performance during sample preparation, dilution and standardisation tasks common in water examination laboratories. Laboratories performing photometric or titrimetric water tests will find this flask a useful addition to their glassware inventory for consistent volumetric results in daily workflows.

Questions about Over-flow-flask 700 ml class B
What is this article?
Over-flow-flask 700 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.
