Description
BLAUBRAND volumetric flask, class A, with PP stopper is a precision laboratory flask made from borosilicate glass 3.3 for accurate volumetric work. With a 50 ml nominal capacity and ground joint 12/21, it is designed for preparing standard solutions, performing quantitative dilutions and supporting calibration tasks in analytical chemistry. Class A tolerance ensures the volumetric accuracy expected in titrations, assay procedures and quality-control environments. The borosilicate glass 3.3 material delivers chemical resistance and thermal stability toward typical laboratory reagents, while the polypropylene stopper gives a secure, inert closure on the ground joint. Supplied as a pack of 2 pieces from manufacturer BRAND, each flask weighs approximately 0,118 kg and is intended for regular use in research, industrial and teaching laboratories. A distinct graduation mark and narrow neck allow precise meniscus reading, supporting reproducible volumetric results. This flask suits laboratories that need class A performance, a 50 ml working volume and a 12/21 ground joint in durable glassware.
This article belongs on Volumetric accessories & certificates, in Volumetric glassware.

Questions about Vol. flask Blaubrand, cl.A, PP stop, Borosil gl. 3.3, 50 ml, grnd.joint 12/21
What is this article?
Vol. flask Blaubrand, cl.A, PP stop, Borosil gl. 3.3, 50 ml, grnd.joint 12/21 is the article on this page. Luminix Health distributes BRAND for laboratory use. It sits in Volumetric accessories & certificates, inside Volumetric glassware, in Labware.
These are the pieces and the papers that belong to volumetric glass: replacement stoppers, and certificates that state the calibration. A certificate without the flask it belongs to does not calibrate a different flask.
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.
