Description
Volumetric flask class A KB wide-neck 50 ml amber glass with PE stopper NS 14/23 is a precision measuring vessel for accurate volumetric preparations. Produced from DURAN® borosilicate glass 3.3, it provides excellent chemical resistance and thermal stability. The nominal volume is 50 ml with a tolerance of ±0,08 ml, conforming to Class A of DIN EN ISO 1042. Amber colouration protects light-sensitive media, while the wider NS 14/23 ground joint accepts the polyethylene stopper and facilitates filling and cleaning. Overall height is 140 mm. Each unit is supplied with a dated batch mark and a declaration of conformity to DIN 12600. Manufacturer Hirschmann offers a free batch calibration certificate, with optional individual or DAkkS certificates available. The wide-neck design suits preparation of standard solutions, handling of viscous or particulate samples and quantitative work in analytical, pharmaceutical and research laboratories that demand both Class A accuracy and light protection. Robust construction supports extended laboratory service.

Questions about VOLUMET. FLASK A CC WN 50 ML, AMBER GLASS POLYST. NS14/23
What is this article?
VOLUMET. FLASK A CC WN 50 ML, AMBER GLASS POLYST. NS14/23 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.
