Description
Burettes amber glass with stopcock and key, 50 ml are volumetric glassware instruments designed for precise titration in analytical chemistry. Each burette has a nominal capacity of 50 ml with 0,1 ml graduation intervals and conforms to DIN class B accuracy requirements. Fabricated from amber glass, the body protects light-sensitive titrants and reagents from photochemical degradation during use. The instruments are fitted with a straight stopcock and an NS glass key that together enable controlled, drop-wise delivery of liquid. Supplied in packs of 2 pieces from manufacturer Witeg, these burettes are suitable for routine acid-base, redox and complexometric titrations in teaching, research and quality-control laboratories where class B tolerance is acceptable. The amber glass construction combined with a classic glass key provides chemical resistance and reliable sealing performance. Net weight is 0,085 kg per unit. The design supports clear meniscus reading and straightforward handling on standard laboratory stands and titration assemblies.

Questions about Burettes class B, with short line gradua
What is this article?
Burettes class B, with short line gradua 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.
