Description
Volumetric flask, trapezoidal, amber, conformity certified, class A is a precision laboratory vessel for preparing and diluting standard solutions to exact nominal volume. Made from Boro 3.3 borosilicate glass with white inscription, the amber body supports work with light-sensitive media while the trapezoidal form improves standing stability on the bench. Each flask is fitted with a matching NS poly stopper on the ground joint and is conformity certified to class A under DIN EN ISO 1042. The 10 ml capacity uses an NS 10/19 socket joint, making the item suitable for small-volume volumetric work in analytical chemistry, quality control and research laboratories. Supplied in a pack of 2 pieces from manufacturer Hecht, these flasks are intended for routine preparation of reference solutions, titrimetric stock dilutions and other applications that require class A volumetric accuracy together with light protection. Clear white markings aid rapid identification of the calibrated volume during daily laboratory use.

Questions about Volumetric flask, trapezoidal, amber, class A, white graduation, with plastic
What is this article?
Volumetric flask, trapezoidal, amber, class A, white graduation, with plastic is the article on this page. Luminix Health distributes Hecht 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.
