Description
Volumetric flask class A KB 500 ml with PE stopper, brown graduated and NS 19/26 is a precision DURAN® borosilicate glass 3.3 vessel engineered for accurate volumetric measurements. The flask delivers a nominal volume of 500 ml with a tolerance of ±0,25 ml, class A accuracy and compliance with DIN EN ISO 1042. It is supplied with a conformity declaration according to DIN 12600 and dated batch identification for complete batch traceability. With a height of 260 mm and a brown graduation featuring 0,25 ml scale division, the flask allows clear meniscus observation; the larger NS 19/26 ground joint is sealed by the accompanying polyethylene stopper. Offered by Hirschmann, the flask can be accompanied by a free batch calibration certificate or by optional individual and DAkkS calibration certificates when higher metrological documentation is required. The robust borosilicate glass 3.3 construction, light-shielding brown graduation and strict class A tolerances render this volumetric flask ideal for analytical chemistry, preparation of volumetric standards and quality-control laboratories that rely on reproducible volume determination.

Questions about VOLUMET. FLASK A CC 500 ML, POLYST. AMBER GRAD. NS19/26
What is this article?
VOLUMET. FLASK A CC 500 ML, POLYST. AMBER 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.
