Description
Volumetric flask 200 ml is a precision Class A measuring vessel intended for accurate preparation of standard solutions and quantitative volumetric analysis. Produced from clear borosilicate glass 3.3, it features a single blue ring mark and graduation that ensure clear meniscus observation. The flask is equipped with a standard ground joint NS 14/23 together with a polyethylene stopper, guaranteeing a secure and chemically inert closure during homogenisation and short-term storage. Conforming to DIN EN ISO 1042, the vessel meets the stringent accuracy demands of analytical chemistry, quality-control and research environments. Supplied by manufacturer Marienfeld in cartons of 10 pieces, the flask offers outstanding chemical resistance and thermal stability for repeated autoclaving and cleaning. The narrow neck and precisely located calibration mark permit exact dilution to the defined volume, while the sturdy construction tolerates routine laboratory use. Suitable for preparing calibration standards, titrants, stock solutions and culture media where volumetric reliability is critical.

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.
