Description
Volumetric flask 50 ml is a precision laboratory flask intended for the accurate preparation and measurement of liquid volumes in chemical and pharmaceutical applications. This class A volumetric flask is produced from high-quality borosilicate glass 3.3 in amber (brown glass) to shield contents from light. It is fitted with a ground joint of size NS 14/23 complete with a matching polyethylene stopper and carries a single white ring mark together with white graduations. Manufactured in accordance with DIN EN ISO 1042, the flask delivers the tight tolerance required for class A volumetric glassware. The nominal volume is 50 ml (0,05 l). These flasks from manufacturer Marienfeld arrive packed in cartons of 10 pieces and are widely used for preparing standard solutions, dilutions and for volumetric analysis. The combination of chemical durability, thermal shock resistance and precise calibration makes the amber volumetric flask a reliable choice for routine and research laboratory work involving light-sensitive substances.

Questions about Volumetric flasks 50 ml,
What is this article?
Volumetric flasks 50 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.
