Description
DURAN® volumetric flask Class A 1000 ml with CoC and batch certificate and blue print is a precision borosilicate glass 3.3 laboratory vessel for accurate volumetric work. Conforming to ISO 1042, the clear flask carries a permanently fired blue print with a printed ring mark for clear meniscus reading and is adjusted to contain (In) at the +20 °C reference temperature. Class A provides the narrowest volume tolerances, delivering the highest measurement precision and process stability. Each flask is supplied with an ergonomic polyethylene stopper that allows fast, secure opening and closing. Flasks bearing a Class A marking and batch number are delivered with a batch certificate that records the batch mean, standard deviation and issue date; certificates are also retrievable online. The four-digit batch code encodes production year and lot. Typical applications include preparation and storage of standard solutions, liquid volume measurement, dilution, multi-component mixing and volumetric analysis. These flasks from manufacturer Duran/DWK Life Sciences feature an NS 24/29 ground joint. To safeguard long-term volumetric integrity, do not heat the glassware above +250 °C in drying ovens or sterilizers. Pack size is 2 pieces.

Questions about DURAN® Volumetric Flask, Class A, with CoC and batch certificate, blue print
What is this article?
DURAN® Volumetric Flask, Class A, with CoC and batch certificate, blue print is the article on this page. Luminix Health distributes DWK Life Sciences 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.
