Description
Volumetric flask without stopper, clear, class A, 200 ml is a precision laboratory vessel for preparing and measuring defined solution volumes in analytical and teaching workflows. The clear body supports straightforward visual inspection and meniscus reading when solutions are filled to the calibration mark, while the Class A rating indicates the higher volumetric accuracy tier used for quantitative work. Supplied without a stopper, the flask can be closed with a laboratory stopper chosen to match the solvent system and handling practice in use. A pack of 10 pieces provides a convenient stock quantity for routine dilution, standard preparation, and general volumetric tasks at the 200 ml nominal capacity. These flasks from manufacturer Dinkelberg originate from the Czech Republic and belong to the standard lab materials range for chemistry and quality-control benches. They suit environments that rely on calibrated volumetric glassware for reproducible solution make-up, sample preparation ahead of titration or instrumental analysis, and day-to-day training in correct volumetric technique. The open-neck design without an included stopper keeps the configuration flexible across different laboratory protocols and storage preferences.

Questions about Flask, volumetric without stopper, clear, Class A, 200ml, 10/PK
What is this article?
Flask, volumetric without stopper, clear, Class A, 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.
