Description
BLAUBRAND volumetric flask, class A, with PP stopper is a precision glass vessel for accurate volumetric analysis in the laboratory. Made from borosilicate glass 3.3, it offers a nominal capacity of 250 ml and a ground joint 14/23 for secure fitting of the polypropylene stopper. Class A calibration supports reliable preparation of standard solutions, quantitative dilutions and reference mixtures where tight volumetric tolerance is essential. The chemically durable borosilicate glass 3.3 body withstands typical thermal and chemical conditions of analytical workflows, while the clear wall allows precise meniscus reading at the calibration mark. The PP stopper closes the ground joint cleanly, helping protect prepared solutions during mixing, standing or short-term holding. Supplied as a pack of 2 pieces from manufacturer BRAND, this flask suits quality-control, research and teaching laboratories performing volumetric work, titrations and assay preparation. Its combination of class A accuracy, defined joint size and practical stopper makes it a dependable choice for routine and demanding volumetric tasks.

Questions about Vol. flask Blaubrand, cl.A, PP stop, Borosil gl.3.3, 250 ml, grnd.joint 14/23
What is this article?
Vol. flask Blaubrand, cl.A, PP stop, Borosil gl.3.3, 250 ml, grnd.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.
