Description
Volumetric flask, brown glass with white graduation, class A, KB, 2000 ml, NS 29/32, coated is a precision laboratory vessel produced from borosilicate glass 3.3. The brown body shields light-sensitive media and the white graduation supports accurate meniscus reading. A specially composed transparent coating covers the flask body like a protective glove; should breakage occur it retains the glass fragments and minimises leakage, frequently keeping hazardous or valuable solutions contained within the vessel. The coating tolerates temperatures up to 135 °C for a maximum of 30 minutes, can be cleaned at up to 95 °C and autoclaved at 121 °C; it must not come into direct contact with an open flame. Technical specifications are identical to those of the corresponding clear and brown uncoated ranges. Supplied as a pack of 2 pieces from manufacturer ISOLAB Laborgeräte, this coated class A flask with NS 29/32 ground joint is recommended for safe volumetric work with critical solutions in analytical, pharmaceutical and quality-control laboratories where both certified accuracy and breakage containment are essential.

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.
