Description
Volumetric flask with plastic stopper NS 14/23, amber, class B, 250 ml is a laboratory flask for preparing and containing accurately measured solution volumes at the 250 ml scale. The amber glass construction helps protect light-sensitive media, while class B volumetric tolerance meets the needs of routine analysis, teaching and quality-control work. A plastic stopper for the NS 14/23 ground joint provides a practical seal during dilution, mixing and short-term holding. Delivered as a pack of 10 pieces, the set is well suited to parallel preparations and shared laboratory stations. These flasks from manufacturer Dinkelberg are of Czech origin and address everyday wet-chemistry tasks that call for a larger 250 ml nominal capacity. The standardised joint ensures compatibility with usual laboratory stoppers and accessories, and the amber finish supports light-protected volumetric work. Choose this class B amber volumetric flask pack when reliable 250 ml volume measurement combined with light shielding is required in the laboratory.

Questions about Flask, volumetric with plastic stopper NS 14/23, brown, Class B, 250ml, 10/PK
What is this article?
Flask, volumetric with plastic stopper NS 14/23, brown, Class B, 250ml, 10/PK is the article on this page. Luminix Health distributes Dinkelberg 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.
