Description
Volumetric flask with plastic stopper NS 14/23 is a clear class B measuring flask for preparing solutions of defined volume in laboratory practice. With a nominal capacity of 200 ml and ground joint NS 14/23, it supports everyday volumetric work where class B accuracy is appropriate. The clear body allows straightforward visual inspection of the liquid level and meniscus when adjusting to the calibration mark. A plastic stopper closes the neck securely and suits repeated opening during dilutions or reagent preparation. Supplied in a pack of 10 pieces from manufacturer Dinkelberg, the set helps stock teaching laboratories, analytical benches and quality-control stations efficiently. These flasks serve standard tasks such as making up standard solutions, performing dilutions and measuring defined volumes. The NS 14/23 joint matches common stopper formats for easy integration into existing glassware sets. Originating from the Czech Republic, the design follows conventional laboratory flask geometry for handling and volume adjustment. Class B designation suits general analytical and educational applications that do not require class A tolerances.

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