Description
Volumetric flask, 10 ml, class A is a precision laboratory measuring vessel for accurate preparation of standard solutions and volumetric analysis. Manufactured from borosilicate glass 3.3 with Diffico brown colouring, it is produced according to USP, conformity certified and fitted with an NS 10/19 ground joint plus PE stopper. Every flask carries a batch number and is supplied with a batch certificate per original packaging from manufacturer Witeg. The class A rating delivers the volume accuracy needed for pharmaceutical quality control, analytical chemistry and research workflows. Each unit has a net weight of 0,014 kg and the flasks are packed in units of 10 pieces. This construction supports reliable dilution, titration and standard-solution preparation while the borosilicate glass 3.3 provides chemical resistance and thermal stability for routine laboratory use. Documented batch traceability together with the certified class A calibration makes the flask suitable for regulated environments requiring consistent volumetric performance.

Questions about Volumetric flask, 10 ml, A, CC, ST 10/19, PE, USP
What is this article?
Volumetric flask, 10 ml, A, CC, ST 10/19, PE, USP 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.
