Description
Class A volumetric flask KB 5 ml with blue graduation and NS 7/16 ground joint is a precision measuring vessel manufactured from DURAN® borosilicate glass 3.3. It provides a nominal volume of 5 ml with a tolerance of ±0,025 ml and a total height of 70 mm, making it suitable for accurate preparation of standard solutions and volumetric work. The flask is supplied without stopper and carries a clear blue graduation scale that remains highly legible under laboratory lighting. Produced in accordance with DIN EN ISO 1042, every unit is accompanied by a conformity declaration to DIN 12600 and a dated batch identification for full traceability. This DURAN® glassware from Hirschmann offers the chemical resistance and thermal stability required for routine analytical chemistry, quality control and research applications. Optional batch calibration certificates are available free of charge; individual or DAkkS calibration certificates can be ordered separately when higher documentation levels are needed. The compact 5 ml format is ideal for small-volume work while maintaining Class A accuracy. Pack size is 2 pieces.

Questions about VOLUMET. FLASK A CC 5 ML, BLUE GRADUATION NS7/16
What is this article?
VOLUMET. FLASK A CC 5 ML, BLUE GRADUATION NS7/16 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.
