Description
Volumetric flask PMP B 50 ml NS 12/21 with poly stopper is a highly transparent plastic laboratory flask intended for accurate volume measurement in analytical and routine laboratory practice. Fabricated from PMP, this class B flask features an individually adjusted ring mark and a ground joint sized NS 12/21. A matching NS stopper in PP closes the neck securely when solutions are prepared, mixed or held briefly on the bench. The design follows DIN EN ISO 1042, giving laboratories a defined class B volumetric tool for workflows that call for this tolerance class. With a 50 ml nominal volume, the flask is well suited to dilutions, sample preparation, reagent formulation and standard solution work in chemistry, life sciences and quality control. High transparency of the PMP body supports confident meniscus reading, while the plastic construction offers a lightweight, break-resistant alternative to glass volumetric flasks. Supplied from manufacturer Hirschmann in a pack of six pieces, the unit combines standardised joint geometry with a practical poly stopper for dependable day-to-day volumetric use.

Questions about VOLUMETRIC FLASK PMP,B 50 ML, NS 10/19, WITH POLYSTOPPER
What is this article?
VOLUMETRIC FLASK PMP,B 50 ML, NS 10/19, WITH POLYSTOPPER is the article on this page. Luminix Health distributes Hirschmann 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.
