Description
Volumetric flask, trapezoidal shape is a laboratory glass vessel intended for accurate make-up and dilution of solutions in volumetric analysis. This 50 ml flask includes a glass stopper and a standard ground joint 12/21, together with blue graduations at the nominal volume mark. The trapezoidal profile provides a practical footprint and steady handling when filling, swirling and equilibrating solutions. Offered as 2 pc(s) per pack and weighing 0,127 kg per unit, it is well suited to everyday analytical, quality-control and teaching workflows. Blue graduation marks support clear visual reading when adjusting to volume. This volumetric flask from manufacturer Hirschmann is appropriate for preparing calibration standards, titrant solutions and diluted samples used in quantitative wet-chemistry methods. The glass stopper and ground joint help reduce evaporation and contamination during short-term holding of prepared liquids. Laboratories that rely on 50 ml volumetric glassware will find this trapezoidal flask a straightforward addition to sets used for solution preparation, transfer and volumetric determination steps.

Questions about Volumetric flask, trapezoidal shape, w. glass stop., st.gr.joint 12/21, 50ml
What is this article?
Volumetric flask, trapezoidal shape, w. glass stop., st.gr.joint 12/21, 50ml 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.
