Description
Volumetric flask, brown glass, white graduation, class A, KB, 20 ml, NS 10/19, coated is a precision measuring vessel of heat-resistant borosilicate glass 3.3 conforming to DIN EN ISO 1042 and calibrated to DIN/ISO class A. The body carries a specially formulated transparent protective coating that acts like a safety glove: in the event of breakage it holds fragments together and greatly reduces leakage of hazardous or valuable solutions. Technical specifications match those of the corresponding uncoated brown volumetric flasks.
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 is autoclavable at 121 °C; direct contact with an open flame must be avoided. White enamel graduations and inscriptions remain clearly visible on the brown glass. Supplied with a leak-proof PE stopper and NS 10/19 joint, this 20 ml coated flask from manufacturer ISOLAB Laborgeräte is recommended whenever extra containment security is required for light-sensitive media. Pack size is 2 pieces.

Questions about volumetric flask - standard - amber - class A - conformity batch sertified -
What is this article?
volumetric flask - standard - amber - class A - conformity batch sertified - is the article on this page. Luminix Health distributes ISOLAB 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.
