Description
Volumetric flask class A KB 50 ml with PE stopper, brown graduated and NS 12/21 joint is a high-precision measuring flask manufactured from DURAN® borosilicate glass 3.3. It features a nominal volume of 50 ml with a tolerance of 0,06 ml and a height of 140 mm, complying fully with DIN EN ISO 1042. The brown glass body shields light-sensitive samples from photodegradation, while the brown graduations allow precise volume determination. Fitted with a polyethylene stopper and standard ground joint NS 12/21, the flask guarantees reliable sealing during solution preparation and storage. Every unit includes a conformity declaration according to DIN 12600 and dated batch recognition for complete traceability. Optional batch, individual or DAkkS calibration certificates are obtainable on request. Suited to volumetric analysis, standard solution preparation and quantitative work in research, quality-control and pharmaceutical laboratories, this class A flask ensures consistent accuracy. The durable construction from manufacturer Hirschmann resists chemical attack and thermal stress. Packaged as 2 pieces, the flask is ready for immediate deployment in demanding laboratory environments.

Questions about VOLUMET. FLASK A CC 50 ML, POLYST. AMBER GRAD. NS12/21
What is this article?
VOLUMET. FLASK A CC 50 ML, POLYST. AMBER GRAD. NS12/21 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.
