Description
Trapezoidal volumetric flask 10 ml Class A TC NS 10/19 with PE stopper is a precision measuring vessel for accurate volumetric work in analytical and quality-control laboratories. Fabricated from borosilicate glass 3.3, the trapezoidal body offers a low centre of gravity and excellent bench stability while the Class A tolerance and to-contain (TC) calibration guarantee reliable volume delivery. The NS 10/19 ground joint accepts the supplied polyethylene stopper for a tight, chemically resistant seal. Clear Diffico blue enamel graduations remain legible even after repeated autoclaving or solvent exposure. Every flask carries an individual batch number and is accompanied by a batch certificate packed with the original unit, ensuring full traceability. Produced by manufacturer Witeg, this compact 10 ml flask is particularly suited to the preparation of standard solutions, titrants and reference materials where space is limited yet metrological confidence is essential. The inherent chemical durability and thermal shock resistance of borosilicate glass 3.3 make the vessel suitable for a wide range of aqueous and organic media encountered in routine laboratory practice.

Questions about Trapezoidal volumetric flasks 10 ml A CC ST 10/19
What is this article?
Trapezoidal volumetric flasks 10 ml A CC ST 10/19 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Labware.
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.
