Description
Trapezoidal volumetric flask BLAUBRAND® class A provides a 25 ml precision vessel in borosilicate glass 3.3 for reliable volumetric work. Blue graduations, DE-M marking and ground joint NS 10/19 are combined with a polypropylene (PP) stopper for secure sealing during preparation and short-term holding of solutions. The trapezoidal profile improves standing stability on the laboratory bench compared with conventional round-bottom designs, reducing the risk of tipping while reagents are added or mixed. Manufactured to class A accuracy and delivered with an ISO individual certificate, the flask supports traceable measurements in research, quality control and routine analysis. Boro 3.3 glass offers the chemical durability expected for aqueous standards and many organic solvents used in everyday laboratory practice. Clear blue graduation marks remain legible under normal lighting conditions. Supplied as one piece from manufacturer Brand, this BLAUBRAND® volumetric flask fits standard workflows that demand defined volume, documented conformity and a practical, stable form factor.

What is this article?
Vol. flask trapezoidal BLAUBRAND class A, 25 ml, with NS 10/19 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.
