Description
Volumetric flask 200 ml is a measuring vessel for precise volume determination and solution preparation in analytical laboratories. This class A flask has a nominal volume of 200 ml and is manufactured in accordance with DIN EN ISO 1042. It is produced from borosilicate glass 3.3 as brown glass and is fitted with a standard ground joint NS 14/23 together with a polyethylene stopper. White graduations feature a single ring mark for accurate meniscus reading. The brown glass construction is intended for work with light-sensitive contents. Packaged in cartons of 10 pieces, the flasks are supplied by manufacturer Marienfeld. They are used for preparing standard solutions, performing dilutions and carrying out volumetric analysis where defined accuracy and light protection are required. The combination of class A tolerances, standardised NS joint, polyethylene stopper and borosilicate brown glass supports routine quantitative laboratory procedures conforming to the stated ISO standard.

Questions about Volumetric flasks 200 ml,
What is this article?
Volumetric flasks 200 ml, is the article on this page. Luminix Health distributes Marienfeld 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.
