Description
Volumetric flask, PMP, class A, with NS stopper 19/26, PP, 250 ml is a plastic laboratory flask for preparing solutions to an exact defined volume. The PMP body provides a nominal volume of 250 ml (0.25 l) and is fitted with a polypropylene (PP) stopper using ground joint NS 19/26. Accuracy class A makes the flask suitable for precise analytical work, quality control and research applications that require class A tolerances. Transparent PMP construction yields a lightweight, shatter-resistant alternative to conventional glass volumetric flasks while preserving the classic pear-shaped geometry and long calibrated neck. Gross weight is 0.086 kg; pack size is 1 piece. This model from manufacturer Vitlab forms part of the standard Messkolben range employed in chemical, pharmaceutical and environmental laboratories for dilutions, standard preparation and sample make-up. The larger NS 19/26 joint matches corresponding stoppers and accessories. Clear volume marking and a stable base support confident handling during everyday volumetric operations, reducing breakage risk compared with glassware of similar capacity.

Questions about Volumetric flask, PMP, class A, 250 ml, with stopper, NS 19/26, with ring-mark,
What is this article?
Volumetric flask, PMP, class A, 250 ml, with stopper, NS 19/26, with ring-mark, is the article on this page. Luminix Health distributes Vitlab 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.
