Description
Volumetric flask 500 ml class A KB with NS 19/26 joint and hexagonal hollow stopper in amber glass provides precise volume measurement for analytical and pharmaceutical laboratory work. Manufactured from borosilicate glass 3.3, the flask features white Diffico graduation and is produced to USP requirements. Each unit carries a batch number and is supplied with a batch certificate in the original packaging, ensuring full traceability and conformity certification. The amber glass protects light-sensitive solutions while the hexagonal hollow stopper secures the ground joint reliably during handling and storage. Offered in packs of 10 pieces from manufacturer Witeg, these flasks suit routine preparation of standard solutions, dilutions and quantitative assays where class A accuracy and certified documentation are essential. The robust construction of borosilicate glass 3.3 delivers chemical resistance and thermal stability required in everyday laboratory practice.

Questions about Volumetric flasks, 500 ml, A, CC, ST 19/26,
What is this article?
Volumetric flasks, 500 ml, A, CC, ST 19/26, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Fioles jaugées, inside Verrerie volumétrique, in Matériel de laboratoire.
A volumetric flask is calibrated to contain one volume at a reference temperature, with a single mark on a narrow neck. Class A is the tight tolerance. It is not a storage bottle and it is not for heating. The stopper is part of the calibrated article.
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.
