Description
Volumetric flask KB 20 ml with blue graduation is a precision glassware item manufactured from borosilicate glass 3.3 for accurate volume measurement in accordance with the prepackaging ordinance. The flask carries a nominal capacity of 20 ml with 0,5 ml scale division, stands 110 mm high and is supplied without a ground joint. Blue graduation markings remain clearly legible against the transparent glass, while a dated batch identification and declaration of conformity to DIN 12600 document traceability and metrological compliance. Intended for preparation of standard solutions, dilution work and quality-control tasks that demand certified volumetric accuracy, the flask is especially suited to regulated packaging and analytical laboratories. Produced under the DURAN ® brand by manufacturer Hirschmann, each unit is delivered in a pack of two pieces. The borosilicate 3.3 construction provides excellent thermal and chemical resistance, supporting repeated autoclaving and exposure to common laboratory reagents. Clear batch coding further simplifies documentation and audit requirements in GMP or ISO environments.

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.
