Description
Volumetric flask, brown glass is a laboratory measuring vessel for preparing solutions to a defined volume in volumetric analysis. This 100 ml flask is made of brown glass, fitted with a glass stopper and a standard ground joint 12/21, and carries white graduations for clear reading of the calibration mark. Brown glass is used where reduced light exposure of the contents is preferred during make-up and short-term holding of solutions. The white graduations stand out against the brown body so the meniscus can be aligned at the mark with good visual contrast. Supplied as a pack of 2 pc(s), with a stated weight of 0,190 kg, the flask is intended for routine quantitative work beside other volumetric glassware. The glass stopper seats in the standard ground joint 12/21 to close the neck after the solution has been brought to volume. From manufacturer Hirschmann, this brown-glass volumetric flask with white graduations supports standard solution preparation, dilutions and volumetric workflows in analytical and teaching laboratories that require a 100 ml nominal capacity with a matching glass stopper.

Questions about Volumetric flask, brown glass, w. glass stop., st.gr.joint 12/21, 100ml
What is this article?
Volumetric flask, brown glass, w. glass stop., st.gr.joint 12/21, 100ml 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.
