Description
Volumetric flask class A KB 500 ml with hollow glass stopper, blue graduated markings and NS 19/26 ground joint is a precision laboratory vessel for accurate volumetric work. Manufactured from DURAN® borosilicate glass 3.3, it offers a nominal volume of 500 ml with a scale division of 0,25 ml and an overall height of 260 mm. Class A accuracy complies with the tolerances of DIN EN ISO 1042. Each flask carries a declaration of conformity according to DIN 12600 together with dated batch identification for complete traceability. The clear blue graduation contrasts well against the transparent glass body, while the hollow glass stopper seats securely in the NS 19/26 joint. This volumetric flask from Hirschmann is well suited for preparing standard solutions, performing dilutions and conducting quantitative analyses in analytical chemistry, pharmaceutical and research laboratories. Optional batch, individual or DAkkS calibration certificates are available on request. The chemically resistant borosilicate glass 3.3 construction provides excellent thermal stability and durability under routine laboratory conditions.

Questions about VOLUMET. FLASK A CC 500 ML, GL.ST. BLUE GRAD. NS19/26
What is this article?
VOLUMET. FLASK A CC 500 ML, GL.ST. BLUE GRAD. NS19/26 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.
