Description
Coated volumetric flask class A, KB, with blue graduation, 300 ml capacity and NS 14/23 joint is intended for safer handling of hazardous or valuable solutions. Technical specifications match those of the corresponding clear and amber class A volumetric flasks: heat-resistant borosilicate glass 3.3, DIN EN ISO 1042 construction, DIN/ISO class A calibration and DE-M conformity marking. The body is covered with a specially formulated transparent coating that acts like a protective glove, holding broken glass together and greatly reducing leakage if the flask is damaged.
This article is part of Volumetric flasks, in Volumetric glassware.
In most cases the coating retains the contents inside the flask body. 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 be exposed to an open flame. Supplied with a leak-proof PP stopper, these coated flasks from manufacturer ISOLAB Laborgeräte combine class A volumetric accuracy with added mechanical protection for demanding laboratory workflows. Pack of 2 pieces.

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 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.
