Description
Volumetric flask, 2000 ml, class A, with NS 29/32 joint and hexagonal hollow stopper in brown glass is a precision measuring vessel manufactured from borosilicate glass 3.3. The amber-brown glass protects light-sensitive solutions, while class A accuracy and conformity certification ensure reliable volumetric work. Each flask carries a batch number and is supplied with a batch certificate in the original packaging. The NS 29/32 ground joint accepts the hexagonal hollow stopper for secure closure, and Diffico white graduations support clear meniscus reading. These flasks from manufacturer Witeg are offered in packs of ten pieces and suit analytical chemistry, quality control and pharmaceutical laboratories that require certified volumetric glassware. Net weight is approximately 0,432 kg per unit. Robust borosilicate construction withstands typical laboratory handling and the thermal demands of preparing standards and reagents, making this brown-glass flask a dependable choice for light-sensitive volumetric applications in both routine and regulated laboratory environments where precision and light protection are essential.

Questions about Volumetric flasks, 2000 ml, A, CC, ST 29/32,
What is this article?
Volumetric flasks, 2000 ml, A, CC, ST 29/32, 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.
