Description
Volumetric flask, brown glass is a laboratory vessel for adjusting liquids to a defined nominal volume in volumetric analysis. This 250 ml flask is made of brown glass, comes with a glass stopper, uses a standard ground joint 14/23, and bears white graduations for reading the calibration line. The brown glass construction is appropriate when reduced light exposure of the filled solution is preferred during preparation and handling. White graduations give clear visual contrast on the brown body so the meniscus can be aligned at the mark. It is supplied in a pack of 2 pc(s) and has a stated weight of 0,230 kg. After the solution is brought to volume, the glass stopper closes the standard ground joint 14/23 neck for mixing. Manufactured by Hirschmann, the flask belongs with other volumetric glassware used for standard solutions, dilutions and quantitative laboratory work that specifies a 250 ml brown-glass volumetric flask with glass stopper and white graduations on a ground joint 14/23.

Questions about Volumetric flask, brown glass, w. glass stop., st.gr.joint 14/23, 250ml
What is this article?
Volumetric flask, brown glass, w. glass stop., st.gr.joint 14/23, 250ml 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.
