Description
Volumetric flasks, class A, DURAN®, trapezoid, 1 ml are compact precision vessels for preparing and handling very small calibrated volumes in volumetric analysis. Made from transparent DURAN® glass in a trapezoid profile, they incorporate a standard ground joint for secure stoppering during mixing and short-term storage of the 1 ml working volume. Class A construction supports accurate meniscus reading and reproducible results where micro-scale dilutions and standard solutions are required. The trapezoid form provides a stable footprint on the bench while the ground joint maintains a reliable seal. Supplied as 2 pc(s) per pack from manufacturer Hirschmann, the unit weight is 0,040 kg. Clear glass allows direct visual inspection of contents and the calibration mark even at this small nominal volume. These 1 ml flasks suit chemical, pharmaceutical and research laboratories that need class A volumetric glassware for low-volume quantitative work, reference preparations and precise dilutions without sacrificing stability or optical clarity at the mark.
This article is part of Volumetric flasks, in Volumetric glassware.

Questions about Volumetric flasks, cl. A, DURAN®, trapezoid, with stand. gr. joint, 1 ml
What is this article?
Volumetric flasks, cl. A, DURAN®, trapezoid, with stand. gr. joint, 1 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.
