DURAN® volumetric flask Class B with white print is a precision measuring vessel intended for preparing and storing standard solutions, diluting liquids and performing volumetric analysis. This 10 ml wide-neck flask is produced from borosilicate glass 3.3 and complies with ISO 1042. Class B volume tolerances are roughly twice those of Class A, delivering dependable results for routine laboratory applications. The flask is adjusted to contain (“In”) at the +20 °C reference temperature and features a printed ring mark that improves meniscus visibility. An ergonomic polyethylene stopper allows fast and secure opening and closing. Permanently fired white print remains durable and legible over extended use. Offered by Duran/DWK Life Sciences, the flask is suited to accurate liquid measurement, component mixing and preparation of normal solutions. To maintain long-term volumetric stability, the glassware should not be heated above +250 °C in drying cabinets or sterilisers. Precise processing, stable borosilicate material and the NS 10/19 joint make this Class B flask a reliable tool for everyday volumetric work.

Questions about DURAN® Volumetric Flask, Class B, white print, with ergonomic polyethylene stopp
What is this article?
DURAN® Volumetric Flask, Class B, white print, with ergonomic polyethylene stopp is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Maatkolven, inside Volumetrisch glaswerk, in Labmateriaal.
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.
