Description
Volumetric flask with plastic stopper NS 14/23, amber, class B, 200 ml is a laboratory measuring flask intended for accurate make-up of solutions to a fixed volume. Amber brown glass reduces exposure of light-sensitive reagents and samples, and the plastic stopper closes the NS 14/23 ground joint for secure mixing and handling. As a class B 200 ml Messkolben it is suitable for routine volumetric work in analytical and teaching laboratories. The pack comprises 10 pieces, allowing several parallel preparations or shared use across benches. These flasks are from manufacturer Dinkelberg, classified as laboratory material and originating from the Czech Republic. The 200 ml graduation and standardised NS 14/23 joint support everyday tasks such as preparing calibration solutions, buffers and diluted samples where class B accuracy and light protection are required. The combination of amber glass and a plastic stopper offers a practical option for general chemistry, quality control and life-science sample preparation without specialised glassware sets.

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