Description
Volumetric flasks, class A, DURAN® provide calibrated vessels for precise volume definition in quantitative laboratory work. This trapezoid version includes a standard ground joint and a 50 ml nominal capacity, matching common preparation volumes for standards, buffers and diluted samples. Class A designation indicates the tighter tolerance band used in analytical chemistry and volumetric analysis. The DURAN® construction delivers the clarity and chemical durability needed for repeated use with aqueous reagents and many solvents. Offered as two pieces per unit, the pack supports paired workflows or spare capacity beside the balance. Unit weight is 0,120 kg, consistent with a mid-size flask that remains easy to handle during mixing by inversion. The trapezoid base promotes upright stability on the bench while the ground joint accepts matching stoppers for secure temporary storage. Manufactured by Hirschmann, these flasks suit titration laboratories, method development and routine QC where reproducible class A glassware is essential. They complement other volumetric flasks and vessels already in service for standardisation, assay preparation and teaching demonstrations that demand traceable volume measurement.
This article belongs on Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, cl. A, DURAN®, trapezoid, with stand. gr. joint, 50 ml
What is this article?
Volumetric flasks, cl. A, DURAN®, trapezoid, with stand. gr. joint, 50 ml 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.
