Description
Trapezoidal volumetric flask 100 ml, class A, TC, with NS 14/23 ground joint and PE stopper is a precision vessel for accurate volumetric work in analytical laboratories. Manufactured from borosilicate glass 3.3, the Diffico brown finish offers chemical resistance, thermal stability and reduced light transmission for light-sensitive solutions. Class A conformity-certified calibration ensures the tight tolerances required for quantitative analysis. Every flask is marked with a batch number and supplied with a batch certificate in each original packaging. The trapezoidal body improves standing stability on the bench, while the polyethylene stopper seals the NS 14/23 joint securely. These flasks from manufacturer Witeg are suited to preparation of standard solutions, dilutions and routine volumetric assays in research, quality-control and teaching laboratories. The pack contains 10 pieces; net weight per flask is 0,06 kg. This configuration provides certified glassware for reliable day-to-day laboratory use.

Questions about Trapezoidal volumetric flasks 100 ml, A, CC,
What is this article?
Trapezoidal volumetric flasks 100 ml, A, CC, 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.
