Description
Volumetric flask, brown glass is a small-volume laboratory vessel for preparing and diluting light-sensitive solutions to a defined volume in volumetric analysis. This 5 ml brown-glass flask is supplied with a glass stopper and a standard ground joint 7/16, and features white graduations for reading the nominal mark against the amber body. Brown glass helps shield contents from ambient light during make-up, equilibration and short-term holding. Pack size is 2 pc(s), with a unit weight of 0,038 kg, convenient for analytical benches and teaching sets that need compact volumetric glassware. White graduation marks remain visible on the brown surface when adjusting to volume. This volumetric flask from manufacturer Hirschmann supports preparation of standards, reagents and sample dilutions where reduced light exposure is preferred. The glass stopper with ground joint assists in limiting evaporation and contamination. It integrates into glassware collections used for quantitative wet chemistry, quality control and educational practicals requiring 5 ml brown volumetric flasks with joint 7/16.

Questions about Volumetric flask, brown glass, w. glass stop., st.gr.joint 7/16, 5 ml, 2 unit(s)
What is this article?
Volumetric flask, brown glass, w. glass stop., st.gr.joint 7/16, 5 ml, 2 unit(s) 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.
