Description
Burettes class B 25 ml with two-way stopcock are clear-glass volumetric tools designed for precise titrant delivery in laboratory titration workflows. They provide a 25 ml capacity graduated in 0,05 ml increments and conform to class B accuracy standards for everyday analytical tasks. The two-way stopcock is fitted with an NS glass plug (key) that enables reliable flow regulation and secure closure. Transparent glass walls allow clear visualisation of the liquid meniscus and colour changes throughout the titration. Offered in packs of 2 pc(s) with a net weight of 0,085 kg each, these burettes from manufacturer Witeg are well suited to routine quantitative analysis in chemistry, quality control and educational laboratories. The two-way stopcock design supports flexible liquid handling while the glass key ensures compatibility with a broad range of aqueous reagents. They constitute a practical choice whenever class B precision meets the required performance level for volumetric work.

Questions about Burettes, Class B, 25ml : 0,05, with Two
What is this article?
Burettes, Class B, 25ml : 0,05, with Two 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.
