Description
Blaubrand class A volumetric flask with PP stopper is a precision laboratory vessel manufactured from borosilicate glass 3.3 for volumetric analysis. With a nominal capacity of 20 ml and a ground joint 12/21, the flask accommodates the polypropylene stopper for reliable closure during solution preparation and handling. Class A volumetric flasks are used when accurate dilution and standard solution make-up are required in analytical laboratories. Borosilicate glass 3.3 delivers the chemical durability expected of laboratory volumetric vessels under routine bench conditions. The PP stopper supports secure retention of contents during mixing and short-term holding of prepared liquids. Offered as a pack of 2 pc(s) with a weight of 0,080 kg, the configuration suits everyday volumetric work. This Blaubrand flask from manufacturer BRAND supports quantitative procedures in research, quality control and teaching laboratories where class A accuracy and a defined 20 ml volume are needed. Ground joint 12/21 with PP stopper provides a practical sealing arrangement for controlled volumetric tasks.
This article belongs on Volumetric accessories & certificates, in Volumetric glassware.

Questions about Vol. flask Blaubrand, cl.A, PP stop, Borosil gl. 3.3, 20 ml, grnd.joint 12/21
What is this article?
Vol. flask Blaubrand, cl.A, PP stop, Borosil gl. 3.3, 20 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.
