Description
Volumetric flask class A KB 5 ml with hollow glass stopper, blue graduation and NS 7/16 ground joint provides precise small-volume measurement for analytical and quality-control applications. Fabricated from borosilicate glass 3.3 under the DURAN® brand, the flask has a nominal volume of 5 ml, a scale division of 25 µl and a height of 70 mm. It conforms to DIN EN ISO 1042 and is delivered with a declaration of conformity according to DIN 12600 together with dated batch coding. The blue graduation offers clear visibility of the meniscus against the transparent glass body, while the hollow glass stopper seals the NS 7/16 joint reliably. Hirschmann supplies this class A instrument ready for laboratory use, with optional free batch calibration certificates and the possibility to order individual or DAkkS certificates for enhanced traceability. Compact dimensions and high accuracy make the flask ideal for preparing standard solutions, titrations and micro-scale dilutions in pharmaceutical, chemical and research laboratories. The durable construction withstands typical cleaning and thermal cycles encountered in routine volumetric work.

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