Description
BLAUBRAND® volumetric flask Class A with beaded rim is a precision laboratory vessel with a nominal capacity of 20 ml. Made from Boro 3.3 glass, it carries blue graduated markings that clearly indicate the calibrated volume for accurate filling to the mark. Class A accuracy is supported by DE-M conformity marking and an ISO individual certificate supplied with the flask. The beaded rim strengthens the neck and aids handling during preparation of solutions and quantitative dilutions. This BLAUBRAND® volumetric flask from manufacturer Brand is offered as a single piece for routine and controlled analytical work where a defined 20 ml volume is required. Blue graduation contrast helps meniscus reading against clear liquids, while the Boro 3.3 body and beaded-rim neck form a robust Class A measuring flask for everyday laboratory use. DE-M marking together with the ISO individual certificate documents the calibrated performance of this blue-graduated 20 ml flask for standard solution work, sample dilution and other volumetric procedures that depend on reliable Class A glassware.

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.
