Questions about Vol. flask Blaubrand, cl.A, PP stop, brown glass, 25 ml, ground joint 12/21
What is this article?
Vol. flask Blaubrand, cl.A, PP stop, brown glass, 25 ml, ground 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.
