Description
Volumetric flask with plastic stopper NS 19/26 is a clear class A measuring flask with a nominal capacity of 500 ml, offered in a practical pack of 10 pieces. It is intended for accurate preparation, dilution and adjustment of standard solutions in analytical and routine laboratory work. The flask combines a clear glass body with a standard ground joint NS 19/26 closed by a plastic stopper, allowing secure sealing during mixing, inversion and short-term holding of liquids while the meniscus remains easy to read. Class A volumetric flasks are produced to tight volumetric tolerances and are therefore well suited to quality-control, research and teaching environments where defined volumes are essential. These flasks from manufacturer Dinkelberg support reproducible volumetric workflows such as titration stock preparation, calibration solutions and general solution make-up. The ten-piece pack helps equip several benches or maintain spare stock. Country of origin is the Czech Republic. The design focuses on clear visibility, reliable joint fit and everyday laboratory handling without unnecessary complexity.

Questions about Flask, volumetric with plastic stopper NS 19/26, clear, Class A, 500ml, 10/PK
What is this article?
Flask, volumetric with plastic stopper NS 19/26, clear, Class A, 500ml, 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.
