Description
Burette DIN-AS with straight stopcock is a clear-glass volumetric burette featuring an NS glass key and a capacity of 10 ml with 0,02 ml graduation. Manufactured to DIN-AS specifications, it is intended for precise titration work in analytical chemistry and laboratory volumetric analysis. The straight stopcock design with NS glass cock supports controlled liquid delivery during titrations. Net and gross weight are each 0,072 kg. Supplied as 2 pc(s), the burette originates from Germany (Baden-Württemberg region) and belongs to the burettes product category. This model from manufacturer Witeg is constructed from clear glass for unobstructed observation of the meniscus and reagent level. It is suitable for routine quantitative analysis, educational laboratories and quality-control environments that require reliable glass burettes conforming to DIN-AS standards. The combination of straight stopcock geometry, fine 0,02 ml scale division and clear-glass body makes the item a practical choice for accurate volumetric measurements in scientific workflows.

Questions about Burettes, class-AS, straight stopcock,
What is this article?
Burettes, class-AS, straight stopcock, is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labware.
A burette delivers a measured volume through a stopcock, which is how a titration is read. Class A and class AS state the tolerance. The stopcock, glass or PTFE, and the volume of the burette are the choices. A dirty bore changes the delivered volume.
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.
