Description
Volumetric flask class A USP 100 ml with PE stopper, blue graduated and NS 12/21 is a precision DURAN® laboratory vessel manufactured from borosilicate glass 3.3. It features a nominal volume of 100 ml with 0,8 ml scale division, a height of 170 mm and a polyethylene stopper that seals the NS 12/21 ground joint securely. Blue graduation markings provide excellent contrast for reliable meniscus reading during preparation of standard solutions, titrations and volumetric dilutions. Class A accuracy combined with USP compliance makes the flask suitable for analytical chemistry, quality control and pharmaceutical work where tight tolerances are required. The chemically resistant borosilicate glass 3.3 construction withstands typical laboratory reagents and thermal stress. Supplied in packs of 2 pieces from manufacturer Hirschmann, each flask is accompanied by the option of a free USP batch calibration certificate downloadable from the manufacturer’s service portal; an individual USP certificate can be ordered separately. This volumetric flask delivers consistent, reproducible results for routine and regulated laboratory applications.

Questions about VOLUMET. FLASK A USP 100 ML, POLYST. BLUE GRAD. NS12/21
What is this article?
VOLUMET. FLASK A USP 100 ML, POLYST. BLUE 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.
