Description
Volumetric flask class A USP 5 ml amber glass with PE stopper NS 10/19 is a high-precision measuring flask manufactured from DURAN® borosilicate glass 3.3 and white-graduated for clear readability. The amber body shields light-sensitive solutions while the nominal volume of 5 ml is held to a tight tolerance of ±0,02 ml. Standing 70 mm high, the flask features a ground joint NS 10/19 closed by a polyethylene stopper. Class A accuracy meets USP requirements as well as the relevant dimensional and performance criteria; a USP batch calibration certificate is available free of charge. The chemically resistant borosilicate glass 3.3 construction provides excellent durability against laboratory reagents and thermal cycling. Supplied by Hirschmann, this USP-compliant volumetric flask is intended for pharmaceutical, analytical and quality-control laboratories that require documented volumetric accuracy. An optional individual USP certificate can be ordered when single-unit traceability is needed. Compact dimensions, light-protective amber glass and precise white graduation marks make the flask a reliable everyday tool for exact volume preparation and dilution work.

Questions about VOLUMET. FLASK A USP 5 ML, AMBER GLASS POLYST. NS10/19
What is this article?
VOLUMET. FLASK A USP 5 ML, AMBER GLASS POLYST. NS10/19 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.
