Description
Clear glass volumetric flask 25 ml with glass stopper and standard ground joint 12/21 is intended for accurate preparation of measured liquid volumes in volumetric analysis and related laboratory procedures. Blue graduations mark the nominal capacity so operators can fill to the calibration line when making standard solutions, dilutions or assay reagents. The transparent glass construction permits easy observation of the meniscus and contents, and the fitted glass stopper seals the neck for mixing by inversion and temporary storage of prepared liquids. Offered as a pack of 2 pc(s) with a unit weight of 0,091 kg, the flasks are convenient for everyday bench use in research, quality control and teaching environments. Produced by manufacturer Hirschmann, this 25 ml format with NS 12/21 joint integrates with common volumetric glassware accessories and stopper systems. Typical applications include stock-solution preparation, quantitative dilution steps and general volumetric work where a defined 25 ml volume and a reliable ground-joint closure are needed.

Questions about Volumetric flask, clear glass, w. glass stop., st.gr.joint 12/21, 25ml
What is this article?
Volumetric flask, clear glass, w. glass stop., st.gr.joint 12/21, 25ml 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.
