Beschrijving
Volumetric flask, class A, KB, blue graduation, PP stopper, coated, 20 ml, NS 10/19 is designed for safer handling of hazardous or valuable solutions. It shares the same technical specifications as the corresponding clear and amber class A volumetric flasks and is manufactured from borosilicate glass 3.3. The body is covered with a specially formulated transparent coating that acts like a protective glove: if breakage occurs, fragments are held together and leakage is minimised, often retaining the contents inside the flask.
This article is part of Volumetric flasks, in Volumetric glassware.
The coating withstands temperatures up to 135 °C for a maximum of 30 minutes, can be cleaned at up to 95 °C and may be autoclaved at 121 °C. Direct contact with an open flame must be avoided. Calibrated to class A accuracy with blue graduation and fitted with a PP stopper and NS 10/19 joint, this 20 ml coated flask from manufacturer ISOLAB Laborgeräte is well suited to analytical work where containment and operator safety matter. Supplied in packs of 2 pieces, it combines volumetric precision with an added protective layer for demanding laboratory applications.

Questions about volumetric flask - standard - clear - class A - conformity batch certified -
What is this article?
volumetric flask - standard - clear - 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 Labmateriaal.
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.
