Description
Burette tube class B, 25 ml, is a clear-glass replacement tube for laboratory titration assemblies. Graduated at 0,05 ml intervals with blue printing, it meets class B volumetric accuracy for routine quantitative work. The 25 ml capacity with fine scale divisions supports precise delivery of titrant in classical wet-chemistry methods. Supplied in a pack of 2 pieces and weighing 0,05 kg net, the tubes serve as spare or replacement components for existing burette setups. This burette tube from manufacturer Witeg is manufactured from clear glass, ensuring good chemical resistance and optical clarity for meniscus reading. Blue graduation markings remain highly visible against the transparent body, facilitating accurate volume determination. Suitable for educational laboratories, quality-control departments and research facilities performing acid-base, redox or complexometric titrations. Class B tolerance is appropriate for many standard analytical procedures where highest-class A precision is not required. The component integrates into complete burette systems used in chemistry teaching and routine analysis.

Questions about Burette-tubes, class B, clear glass 25
What is this article?
Burette-tubes, class B, clear glass 25 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.
