Description
Volumetric flask with plastic stopper NS 12/21, clear, Class B, 100 ml is a laboratory vessel for preparing and measuring standard solutions at intermediate volume. The clear glass body is fitted with a plastic stopper on an NS 12/21 joint, supporting straightforward closure during mixing and short-term holding of prepared liquids. Class B accuracy is appropriate for general analytical work, teaching laboratories and quality-control applications where Class B tolerance meets method requirements. The 100 ml nominal capacity covers frequent dilution, calibration and assay preparation steps. Supplied in a pack of 10 pieces from manufacturer Dinkelberg, the set is convenient for shared benches and routine wet-chemistry workflows. Clear glass allows easy meniscus reading and visual checks of solution appearance. The plastic stopper with NS 12/21 joint offers a practical, lightweight seal for everyday laboratory handling. These volumetric flasks are intended for reference-solution preparation, sample dilutions and quantitative procedures that depend on accurate fill-to-mark volume in the 100 ml range.

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