Description
DURAN® volumetric flask Class A amber provides large-volume precision measurement for light-sensitive samples in analytical and preparative work. Fabricated from borosilicate glass 3.3 with a nominal capacity of 2000 ml, it conforms to ISO 1042 Class A accuracy limits and includes a Certificate of Conformity together with a batch certificate stating mean value, standard deviation and issue date. External amber coating affords UV shielding while the interior retains unaltered DURAN® glass characteristics, delivering durable colouring and solid chemical resistance. White fired-on print and a sharp ring mark guarantee permanent readability; the NS 29/32 ground joint is sealed by the ergonomic polyethylene stopper supplied with each flask. Calibrated to contain (In) at the reference temperature of +20 °C, the vessel supports accurate liquid metering, dilution, multi-component blending, titrimetry and general volumetry. Available from manufacturer Duran/DWK Life Sciences in packs of 2 pieces, these flasks suit storage and transport of photosensitive materials. Do not exceed +250 °C in drying ovens or sterilizers so that volumetric integrity is preserved over extended use.

Questions about DURAN® Volumetric Flask, Class A, amber, CoC and batch certificate, white print
What is this article?
DURAN® Volumetric Flask, Class A, amber, CoC and batch certificate, white 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.
