Description
Clear glass volumetric flask 50 ml with glass stopper and standard ground joint 12/21 supports preparation and dilution of defined liquid volumes for volumetric analysis and quantitative laboratory work. Blue graduations indicate the nominal fill level, aiding consistent reading of the meniscus when making standard solutions, reagents or diluted samples. The clear glass body allows direct visual inspection during filling and mixing, while the glass stopper provides a secure closure for inversion and short-term holding of contents. Supplied in packs of 2 pc(s), each flask weighs 0,119 kg and is suited to routine use on the analytical bench in research, quality-control and educational laboratories. These vessels from manufacturer Hirschmann combine a 50 ml capacity with an NS 12/21 ground joint that matches widely used stopper and accessory formats. They are appropriate for stock-solution make-up, serial dilutions and assay preparation wherever a fixed 50 ml volume and a reliable ground-joint seal are required.

Questions about Volumetric flask, clear glass, w. glass stop., st.gr.joint 12/21, 50ml
What is this article?
Volumetric flask, clear glass, w. glass stop., st.gr.joint 12/21, 50ml is the article on this page. Luminix Health distributes Hirschmann 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.
