Description
BLAUBRAND volumetric flask class A with PP stopper is a brown-glass laboratory vessel with a 250 ml nominal capacity and ground joint 14/23 for precise volumetric work. This class A flask supports preparation and measurement of exact solution volumes in analytical and routine laboratory practice. The brown glass body is paired with a polypropylene stopper that seats in the ground joint, enabling secure closure during mixing, standing and transfer steps. Offered as a pack of 2 pc(s) with a weight of 0,260 kg, the configuration suits laboratories that keep several class A flasks ready for parallel preparations. This BLAUBRAND flask from manufacturer BRAND belongs to the established range of volumetric glassware used for quantitative analysis. The ground joint 14/23 matches common stopper formats for this capacity. Typical use includes volumetric analysis, standard solution preparation and dilution where class A accuracy is specified. Brown glass, class A rating and a PP stopper together define a clear specification set for 250 ml measured volumes in chemical and quality-control laboratories following volumetric flask protocols.

Questions about Vol. flask Blaubrand, cl.A, PP stop, brown glass, 250 ml, ground joint 14/23
What is this article?
Vol. flask Blaubrand, cl.A, PP stop, brown glass, 250 ml, ground joint 14/23 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.
