Description
Volumetric flask 50 ml, class A with batch certificate, features an NS 14/23 ground joint and PE stopper for precise volumetric work. Manufactured from borosilicate glass 3.3, this Diffico-blue flask is conformity certified and supplied with a batch number on each unit together with a batch certificate per original packaging. Class A accuracy supports reliable preparation of standard solutions and quantitative measurements in analytical chemistry. The polyethylene stopper ensures a secure seal during storage and handling, while the standardised NS 14/23 joint maintains compatibility with common laboratory glassware. With a 50 ml capacity the flask is suited to routine titration, dilution and calibration procedures. Packs contain 10 pieces, each with a net weight of 0,039 kg. These volumetric flasks from manufacturer Witeg combine the chemical resistance and thermal stability of borosilicate 3.3 glass with clear Diffico-blue graduation markings, delivering consistent performance for research, quality-control and teaching laboratories that require traceable volumetric glassware.

Questions about Volumetric flask, 50 ml, A, CC, ST 14/23, PE
What is this article?
Volumetric flask, 50 ml, A, CC, ST 14/23, PE is the article on this page. Luminix Health distributes Witeg 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.
