DURAN® volumetric flask Class A 1000 ml wide-neck with CoC and batch certificate and blue print is a high-accuracy borosilicate glass 3.3 vessel intended for precise laboratory volumetry. Manufactured to ISO 1042, the clear flask displays a durable blue print including a ring mark for reliable meniscus observation and is calibrated to contain (In) at +20 °C. Class A tolerances guarantee the tightest volume limits and excellent process reproducibility. The wide-neck design with NS 29/32 joint facilitates filling and cleaning while the ergonomic polyethylene stopper ensures quick, secure closure. Every Class A flask carrying a batch number is accompanied by a batch certificate stating the measured mean, standard deviation and certificate date; the same documents are available online. The four-digit batch identifier shows year of manufacture and lot sequence. Suitable applications cover preparation and storage of normal solutions, measurement of liquid quantities, dilution, component mixing and classical volumetric analysis. These wide-neck flasks from manufacturer Duran/DWK Life Sciences combine maximum precision with practical handling. Avoid heating above +250 °C in drying cabinets or sterilizers to maintain long-term volume stability. Pack size is 1 piece.

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.
