Description
Volumetric flask with glass stopper NS 14/23 is a clear Class B laboratory measuring flask with a nominal capacity of 200 ml for preparing and diluting solutions to a defined volume. The flask carries a standard ground joint NS 14/23 and is fitted with a matching glass stopper that closes the neck securely during inversion, mixing and short-term holding of liquids. Clear glass construction supports straightforward visual checks of fill level and meniscus alignment at the graduation mark. Supplied as a pack of 10 pieces, the set is practical for parallel sample work, teaching benches and routine wet-chemistry stations. These volumetric flasks from manufacturer Dinkelberg originate in the Czech Republic and are intended for general analytical and educational use where Class B volumetric glassware is specified. The NS 14/23 joint size matches common laboratory stoppers and accessories of the same nominal designation, helping keep setups consistent across the bench. Each 200 ml flask provides a single defined volume mark suited to solution make-up, standard preparation and everyday volumetric tasks in the laboratory.

Questions about Flask, volumetric with Glass stopper NS 14/23, clear, Class B, 200ml, 10/PK
What is this article?
Flask, volumetric with Glass stopper NS 14/23, clear, Class B, 200ml, 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.
