Description
Trapezoidal volumetric flask BLAUBRAND® class A, 5 ml, provides a precision borosilicate glass 3.3 vessel for reliable volumetric measurement in the laboratory. Its trapezoidal profile offers a broad, stable base that reduces tipping risk during filling, dilution and standing on the bench, while blue graduations aid straightforward volume assessment. The flask is calibrated to class A accuracy with DE-M marking and is therefore appropriate for preparing standard solutions, performing dilutions and supporting quantitative analytical methods. The neck carries a ground joint NS 7/16 and is fitted with a polypropylene (PP) stopper for dependable closure. An ISO individual certificate accompanies each unit, supporting traceable quality documentation in research, industrial and quality-control settings. Boro 3.3 construction delivers the chemical and thermal resistance expected for everyday wet-chemistry applications. This 5 ml BLAUBRAND® trapezoidal measuring flask from manufacturer Brand balances small working volume with class A performance, making it a practical choice for sample preparation, calibration solutions and routine volumetric tasks. Packaged as one piece for convenient laboratory use.

Questions about Vol. flask BLAUBRAND trapezoidal class A, 5 ml, with NS 7/16 PP stopper, DE-M
What is this article?
Vol. flask BLAUBRAND trapezoidal class A, 5 ml, with NS 7/16 PP stopper, DE-M is the article on this page. Luminix Health distributes BRAND 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.
