Description
Volumetric flask 2 ml, class A, conformity certified, with NS 10/19 ground joint and hexagonal hollow stopper in amber glass is designed for high-precision small-volume measurements. Produced from borosilicate glass 3.3, the flask carries white Diffico markings that remain clearly legible. Each unit is marked with a batch number and supplied together with a batch certificate per original packaging, ensuring complete traceability of the production lot. The amber glass protects light-sensitive reagents and solutions during preparation and short-term storage. Class A accuracy makes the flask suitable for exact volumetric operations in analytical chemistry, pharmaceutical laboratories and quality-control settings where small nominal volumes are required. The hexagonal hollow stopper provides a reliable closure and the NS 10/19 joint fits standard laboratory connectors. Available in packs of 10 pieces from manufacturer Witeg, these compact volumetric flasks offer the durability and chemical resistance of borosilicate glass 3.3 together with certified conformity for precise micro-scale work.

Questions about Volumetric flasks, 2 ml, A, CC, ST 10/19,
What is this article?
Volumetric flasks, 2 ml, A, CC, ST 10/19, 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.
