Description
Volumetric flask 100 ml class A with batch certificate is a precision laboratory vessel featuring an NS 14/23 ground joint and hexagonal hollow stopper in amber glass. Produced from borosilicate glass 3.3, it delivers the chemical resistance and thermal stability required for accurate volumetric work. The amber colouration protects light-sensitive solutions during preparation and storage of standards. Diffico white graduation markings ensure clear readability under laboratory lighting. Every flask carries a batch number and is accompanied by a batch certificate supplied with each original packaging unit, confirming conformity to class A tolerances. These flasks from manufacturer Witeg support quantitative analysis, solution preparation and calibration procedures in analytical chemistry. The hexagonal hollow stopper provides a secure, easy-to-handle closure that maintains the integrity of the ground joint. Net weight is 0,054 kg per flask. The design meets the demands of routine and high-precision laboratory environments where reproducible volumes and documented batch traceability are essential for reliable results.

Questions about Volumetric flasks, 100 ml, A, CC, ST 14/23,
What is this article?
Volumetric flasks, 100 ml, A, CC, ST 14/23, 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.
