Description
Burette 50 ml DIN-AS amber glass is a volumetric glassware item manufactured to DIN-AS requirements for precise titration work. The burette offers a 50 ml capacity with 0,1 ml graduation, a valve stopcock fitted with a PTFE spindle, KB designation and amber-glass construction that protects light-sensitive titrants. Supplied in a pack of 2 pc(s), each unit has a net weight of 0,078 kg and an identical gross weight of 0,078 kg. Produced in Germany (Baden-Württemberg), the burette from manufacturer Witeg carries UNSPSC classification 41121808. Amber glass reduces photochemical degradation of reagents during extended titrations, while the PTFE spindle ensures smooth, chemically resistant stopcock operation. Analytical, pharmaceutical and quality-control laboratories employ this DIN-AS burette for accurate delivery of titrant in classical volumetric analysis. The two-piece pack supports parallel workflows or reserve capacity at the bench. Standard cleaning and conditioning procedures for classed volumetric glassware maintain the stated accuracy across repeated use cycles.

Questions about Burettes DIN AS 50 ml:0,1 with straight
What is this article?
Burettes DIN AS 50 ml:0,1 with straight 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.
