Description
Volumetric flask with plastic stopper NS 12/21, clear, Class A, 100 ml is a standard laboratory flask for accurate make-up and containment of defined solution volumes. The clear glass construction enables straightforward meniscus reading at the graduation mark, while the plastic stopper with ground joint NS 12/21 gives a convenient, secure closure for inversion mixing and interim storage of prepared solutions. Supplied in a pack of 10 pieces, these Class A 100 ml flasks support everyday quantitative tasks such as dilution series, stock and working solution preparation, and quality-control sample work-up. The nominal 100 ml capacity aligns with common analytical protocols that require intermediate volumes between micro and larger flask sizes. Produced in the Czech Republic and offered from manufacturer Dinkelberg, the flasks fit established laboratory glassware sets used in research, industrial QC and teaching environments. Clear visibility, Class A accuracy and a plastic NS stopper make this multi-piece pack a practical choice wherever reliable volumetric glassware is needed for routine solution preparation.

Questions about Flask, volumetric with plastic stopper NS 12/21, clear, Class A, 100ml, 10/PK
What is this article?
Flask, volumetric with plastic stopper NS 12/21, clear, Class A, 100ml, 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.
