Description
Volumetric flask 50 ml, polypropylene is a Class B measuring flask produced according to DIN EN ISO 1042 and calibrated to contain (In) for dependable volumetric preparation. It features an individually adjusted ring mark and a polypropylene screw cap with GL 18 thread for secure closure during mixing and handling. Made from polypropylene (PP), the flask is autoclavable at 121 °C and rated for a maximum operating temperature of 125 °C, delivering a lightweight, break-resistant alternative to glass with suitable chemical resistance for many aqueous laboratory media. Delivered in packs of two pieces, these flasks from manufacturer Marienfeld are practical for dilutions, standard-solution make-up and quantitative transfers in teaching, research and quality-control laboratories. Class B accuracy covers routine analytical tasks where Class A glassware is unnecessary. The distinct ring graduation and robust screw cap help preserve sample integrity, while the plastic body reduces breakage risk in daily use. Nominal volume is 50 ml (0,05 l), providing a convenient size for medium-scale preparations and series work.

Questions about Volumetric flasks 50 ml, polypropylene,
What is this article?
Volumetric flasks 50 ml, polypropylene, is the article on this page. Luminix Health distributes Marienfeld 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.
