Description
Class B burette with straight stopcock and NS glass plug, 25 ml, brown printed is a volumetric glassware item intended for routine titration and quantitative liquid dispensing in analytical and teaching laboratories. The clear glass body carries a brown printed scale with 0,05 ml graduation intervals over the full 25 ml capacity, supporting class B accuracy for general laboratory work. A straight stopcock fitted with an NS glass plug provides controlled delivery of titrant. Supplied in packs of 6 pieces, each unit has a net weight of 0,072 kg and originates from Germany. These burettes from manufacturer Witeg suit standard acid-base, redox and complexometric titrations where class B tolerance is acceptable. The brown scale markings remain clearly legible against light backgrounds and typical laboratory lighting. The straight-bore stopcock design allows straightforward cleaning and maintenance between runs. Ideal for educational settings, quality-control benches and routine analytical workflows that require reliable volume measurement without the tighter tolerances of class A glassware. The robust glass construction withstands normal laboratory handling while the NS glass plug ensures a secure, greaseable seal for smooth operation during serial titrations.

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