Description
Volumetric flask, brown glass is a precision laboratory vessel for preparing and diluting solutions in volumetric analysis. This 500 ml flask is made of brown glass to shield light-sensitive media and comes with a glass stopper on a standard ground joint 19/26. White graduations give a clear volume mark for everyday analytical work. Supplied as a pack of 2 pc(s) with a stated weight of 0,417 kg, it supports reproducible measuring tasks in chemical, pharmaceutical and environmental laboratories. The amber body helps limit photochemical change in sensitive reagents while solutions are mixed or held briefly before use. The glass stopper and standard ground joint allow secure closure for inversion mixing and intermediate storage of calibrated solutions. This Hirschmann flask fits established volumetric workflows where brown-glass protection and a classic ground-glass seal are required. It is suited to stock solutions, dilutions and reference standards under controlled lab conditions and integrates readily into glassware sets used for titration and quantitative chemistry. Durable construction and clear white markings support consistent handling across routine series measurements.

Questions about Volumetric flask, brown glass, w. glass stop., st.gr.joint 19/26, 500ml
What is this article?
Volumetric flask, brown glass, w. glass stop., st.gr.joint 19/26, 500ml 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.
