Description
BLAUBRAND volumetric flask, class A, with PP stopper is a precision laboratory vessel made from borosilicate glass 3.3 for accurate volumetric analysis. With a nominal capacity of 25 ml and ground joint 10/19, it supports reliable preparation of standard solutions, quantitative dilutions and calibration mixtures in analytical chemistry. Class A tolerance delivers the volumetric accuracy required for titrations, assay work and quality-control procedures. The borosilicate glass 3.3 body offers strong chemical resistance and thermal stability against common laboratory reagents, while the polypropylene stopper provides a secure, inert closure at the ground joint. Supplied as a pack of 2 pieces from manufacturer BRAND, each flask weighs approximately 0,080 kg and is intended for routine use in research, industrial and teaching laboratories. A clear graduation mark and narrow neck facilitate precise meniscus reading, helping analysts obtain reproducible results across repeated volumetric measurements. This flask fits standard volumetric analysis workflows where glass quality, joint compatibility and class A performance are essential.
This article belongs on Volumetric accessories & certificates, in Volumetric glassware.

Questions about Vol. flask Blaubrand, cl.A, PP stop, Borosil gl. 3.3, 25 ml, grnd.joint 10/19
What is this article?
Vol. flask Blaubrand, cl.A, PP stop, Borosil gl. 3.3, 25 ml, grnd.joint 10/19 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.
