Description
Volumetric flasks are available in two different accuracy Classes: Class A and Class B. The two Classes differ in the accuracy of measurement with Class A being the highest accuracy, and Class B is approximately half that of Class A. The volumetric flasks with accuracy Class A have a blue print for clear glass products and a white print for amber versions. Volumetric flasks with a batch number and accuracy Class A are supplied with a batch certificate. This certificate documents the mean value obtained from measuring the batch in question, the standard deviation and the day of issue. The batch certificates can also be retrieved online. The batch number consists of four digits. The first two numbers specify the production year, and the following two numbers specify the batch, e.g.: 18.01.
Features and Benefits:
- Complies with ISO 1042
- Manufactured from borosilicate glass 3.3
- UV protection due to external colouration; very durable and chemically resistant amber colour. The only external application of the colour ensures that internal surfaces have standard DURAN® glass properties.
- Outstanding precision during volumetric measurement and high-quality process stability
- Thanks to the exact processing and precisely calibrated scales, they permit the highly accurate determination and measurements of volume
- Supplied with ergonomic polyethylene stopper for easy and safe tightening or removal
- Calibration based on the poured in volume (“In”) at a + 20 °C reference temperature
- The volume content tolerances conform to accuracy Class A
- With etched graduation mark
- Fired-on, highly durable white print
Application: Storage and transport of light-sensitive materials, Measuring liquid amounts, Diluting solutions, Mixing several components, Measurement analysis, Volumetric measurement, To ensure a long service life for your volumetric glassware and to exclude possible volume changes, these glass products should not be heated above + 250 °C in drying cabinets or sterilisers.

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 Matériel de laboratoire.
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.
