Description
Burette class B with two-way stopcock, 5 ml is a clear-glass volumetric instrument intended for routine titration and quantitative liquid dispensing in analytical laboratories. It offers a nominal capacity of 5 ml with fine 0,02 ml graduations, enabling controlled delivery of reagents during acid-base, redox or complexometric determinations. The integrated two-way stopcock fitted with an NS glass plug provides reliable on/off and directional flow control while remaining chemically inert to most aqueous and organic media. Manufactured from transparent borosilicate-type clear glass, the burette permits unobstructed observation of the meniscus and liquid column. Packaged as 2 pc(s) with a net weight of 0,08 kg, the unit is well suited to teaching laboratories, quality-control benches and general research environments where class B tolerance is acceptable. This model from manufacturer Witeg combines straightforward construction with durable stopcock geometry, supporting repeated filling and emptying cycles without leakage. Its compact 5 ml volume is particularly practical for micro-scale titrations and scarce sample work, while the clear barrel ensures easy cleaning and visual inspection between runs.

Questions about Burettes, Class B with two-way stopcock 5ml
What is this article?
Burettes, Class B with two-way stopcock 5ml 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.
