Beschrijving
Volumetric flask 25 ml, polypropylene is a Class B laboratory flask manufactured to DIN EN ISO 1042 and calibrated to contain (In) for accurate volume definition. An individually adjusted ring mark provides the reference line, while a polypropylene screw cap with GL 18 thread secures the contents during preparation and handling. The polypropylene (PP) body is autoclavable at 121 °C and may be used up to a maximum operating temperature of 125 °C, offering a durable, lightweight option with useful chemical resistance for many aqueous solutions. Packed two pieces per unit, these volumetric flasks from manufacturer Marienfeld support routine dilutions, standard solutions and quantitative work in education, research and quality-control settings. Class B tolerance meets everyday laboratory needs when the highest Class A precision is not essential. Clear graduation and a reliable screw closure aid sample integrity, and the plastic construction lowers breakage risk compared with glass. With a nominal volume of 25 ml (0,025 l), the flask is well suited to mid-scale preparations and repeated series measurements on the bench.

Questions about Volumetric flasks 25 ml, polypropylene,
What is this article?
Volumetric flasks 25 ml, polypropylene, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Volumetric flasks, inside Volumetric glassware, in Labmateriaal.
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.
