Description
Volumetric flask, brown glass with white graduation, class A, KB, 500 ml, NS 19/26, coated is a safety-enhanced measuring vessel for handling hazardous or valuable solutions. Technical specifications match the corresponding uncoated brown-glass class A flasks: heat-resistant borosilicate glass 3.3, DIN EN ISO 1042 construction, DIN/ISO class A calibration and NS 19/26 joint. The body is covered with a specially formulated transparent coating that acts like a protective glove, holding fragments together if the glass breaks and thereby reducing impact effects and leakage risk; in most cases the liquid remains contained inside the coated body.
This article is part of Volumetric flasks, in Volumetric glassware.
The coating withstands temperatures up to 135 °C for a maximum of 30 minutes, may be cleaned at up to 95 °C and can be autoclaved at 121 °C; it must not contact an open flame. This coated flask from manufacturer ISOLAB Laborgeräte combines class A volumetric accuracy with added mechanical protection, making it suitable for quantitative work with light-sensitive, hazardous or high-value media where breakage containment is important.

Questions about volumetric flask - standard - amber - class A - conformity batch certified -
What is this article?
volumetric flask - standard - amber - class A - conformity batch certified - is the article on this page. Luminix Health distributes ISOLAB for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, 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.
