Volumetric flask 5 ml, class A, conformity certified (KB), with pouring spout (MA), NS 10/19 joint and PE stopper enables accurate small-volume work together with convenient dispensing. Produced from borosilicate glass 3.3 in Diffico brown, the flask provides chemical resistance and thermal stability suitable for routine laboratory applications. Each unit from manufacturer Witeg is identified by a batch number and accompanied by a batch certificate per original packaging, guaranteeing traceability. The brown finish protects light-sensitive media while the integrated spout facilitates controlled pouring of prepared solutions. Nominal capacity of 5 ml supports precise micro-dilutions, standard preparation and quantitative procedures in analytical chemistry. Supplied in packs of 10 pieces, these class A flasks satisfy demanding accuracy requirements. The polyethylene stopper secures the contents and the NS 10/19 ground joint ensures interchangeability with common laboratory glassware, making the spouted design especially practical for workflows that combine volumetric accuracy with easy transfer of liquids.

Questions about Volumetric flask, 5 ml, A, CC, ST 10/19, w. spout
What is this article?
Volumetric flask, 5 ml, A, CC, ST 10/19, w. spout 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.
