Description
DURAN® volumetric flask Class A with individual certificate and CoC is a clear 50 ml precision vessel featuring durable blue print for laboratory volumetry. Manufactured from borosilicate glass 3.3, it meets ISO 1042 and delivers the tightest Class A volume tolerances for maximum measurement accuracy and process stability. An individual serial number is permanently laser-etched into the base and recorded on the certificate, which documents the measured volume, measurement uncertainty and date of issue. The flask carries a printed ring mark for clear visibility and an NS 12/21 ground joint. It is supplied with an ergonomic polyethylene stopper that enables rapid, secure opening and closing, and is calibrated to contain (In) at the +20 °C reference temperature. These flasks from manufacturer Duran/DWK Life Sciences are ideal for preparing and storing standard solutions, measuring liquid volumes, diluting solutions, mixing components, titrimetric analysis and general volumetric work. Precise forming and scaling guarantee reliable volume determination. To preserve long-term dimensional stability, the glassware should not be heated above +250 °C in drying ovens or sterilizers. Available as a pack of 2 pieces.

Questions about DURAN® Volumetric Flask, Class A, individual certificate and CoC, blue print
What is this article?
DURAN® Volumetric Flask, Class A, individual certificate and CoC, 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.
