Description
DURAN® volumetric flask, Class B, 2000 ml is a precision laboratory vessel intended for accurate volume determination and solution preparation. Produced from borosilicate glass 3.3, it meets ISO 1042 requirements and features durable white printed markings with a clear ring mark for improved readability of the calibration line. The flask is adjusted to contain (In) at the reference temperature of +20 °C and is delivered with an ergonomic polyethylene stopper for rapid, secure opening and closing during routine work. Class B accuracy offers dependable volumetric performance for standard analytical tasks, with tolerances approximately twice those of Class A. From manufacturer Duran/DWK Life Sciences, this flask is well suited to preparing and storing standard solutions, measuring liquid volumes, diluting solutions, mixing multiple components, titrimetric analysis and general volumetry. Precise processing and scaling ensure high process stability and lasting measurement reliability. The white print remains permanently legible under normal laboratory conditions. To preserve volumetric integrity and prevent volume changes, the glassware should not be heated above +250 °C in a drying oven or sterilizer. Ground joint size is NS 29/32.

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 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.
