Description
Volumetric flask 10 ml, class A with batch certificate is a precision laboratory flask for reliable volume measurement and standard solution preparation. Fabricated from borosilicate glass 3.3, it is equipped with an NS 10/19 ground joint and a PE stopper. Diffico blue graduation markings provide durable, easy-to-read calibration lines under typical laboratory lighting. Each flask from manufacturer Witeg is marked with a batch number and delivered with a conformity batch certificate per original packaging, enabling straightforward traceability. Class A accuracy ensures compliance with demanding volumetric tolerances used in analytical chemistry, pharmaceutical testing and research applications. The borosilicate glass 3.3 body combines chemical resistance with good thermal stability for repeated laboratory cycles. Net weight is 0,014 kg, supporting compact storage and handling. Supplied in packs of 10 pieces, this volumetric flask helps laboratories maintain consistent calibrated capacity across multiple workstations while retaining batch-level documentation for quality systems.

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