Description
Volumetric flask, brown glass is a compact laboratory vessel for bringing light-sensitive solutions to a defined volume in volumetric analysis. This 5 ml brown-glass flask is equipped with a glass stopper and a standard ground joint 10/19, and carries white graduations for clear reading of the nominal volume mark. The amber body helps reduce exposure of contents to ambient light during filling, mixing and short-term storage. Supplied as 2 pc(s) per pack with a unit weight of 0,045 kg, it suits routine analytical, quality-control and teaching applications that need small brown volumetric flasks. White graduation marks contrast with the brown glass when adjusting solutions to volume. This volumetric flask from manufacturer Hirschmann is suitable for preparing standards, reagents and diluted samples where light protection is desirable. The glass stopper and ground joint help limit evaporation and airborne contamination of prepared liquids. It fits readily into glassware sets used for quantitative wet-chemistry methods and practical courses requiring 5 ml brown volumetric flasks with joint 10/19.

Questions about Volumetric flask, brown glass, w. glass stop., st.gr.joint 10/19, 5 ml
What is this article?
Volumetric flask, brown glass, w. glass stop., st.gr.joint 10/19, 5 ml 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.
