Description
Volumetric flask 1000 ml class A batch certificate NS 29/32 with spout is a precision class A measuring flask designed for accurate volumetric determinations. Fabricated from borosilicate glass 3.3, it incorporates a pouring spout, a NS 29/32 ground joint and a PE stopper, and is finished in Diffico brown to shield light-sensitive solutions. Every flask bears a batch number and is accompanied by a batch certificate included in the original packaging, thereby documenting conformity. These volumetric flasks from manufacturer Witeg are conformity-certified and appropriate for analytical chemistry, pharmaceutical work and quality-control procedures that rely on class A accuracy. The 1000 ml capacity facilitates preparation of standard solutions and larger dilutions, while the borosilicate glass 3.3 body ensures chemical durability and thermal resilience. Supplied in packs of 10 pieces, the flasks provide a convenient laboratory stock and retain complete batch traceability via the enclosed certificate.

Questions about Volumetric flask, 1000 ml, A, CC, ST 29/32,
What is this article?
Volumetric flask, 1000 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.
