Description
Class A wide-neck volumetric flask KB 5 ml with blue graduation and NS 10/19 ground joint is a precision laboratory flask made from DURAN® borosilicate glass 3.3. The wide-neck design facilitates easy filling, cleaning and transfer of powders or viscous liquids while retaining a nominal volume of 5 ml and a tolerance of ±0,04 ml. Standing 70 mm high and supplied without stopper, the flask features a durable blue graduation scale for clear volume reading. Manufactured to DIN EN ISO 1042, each piece includes a conformity declaration according to DIN 12600 and dated batch identification for complete traceability. This DURAN® volumetric flask from Hirschmann combines Class A accuracy with the chemical and thermal resistance of borosilicate glass 3.3, making it well suited for analytical chemistry, sample preparation and quality-control laboratories. Free batch calibration certificates are obtainable on request; individual or DAkkS certificates can be supplied when required. The larger NS 10/19 joint improves handling convenience without compromising volumetric performance. Pack size is 2 pieces.

Questions about VOLUMET. FLASK A CC WN 5 ML, BLUE GRADUATION NS10/19
What is this article?
VOLUMET. FLASK A CC WN 5 ML, BLUE GRADUATION NS10/19 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.
