Burette class B 25 ml:0,05 with 2-way stopcock and Schellbach stripe is a versatile volumetric glassware item designed for precise liquid handling in titration and analytical procedures. It features a 25 ml capacity with 0,05 ml graduations and class B accuracy suitable for routine laboratory measurements. The two-way stopcock is equipped with an NS glass plug, enabling flexible flow routing and controlled delivery of titrant. A continuous Schellbach stripe along the scale produces a distinct optical boundary that aids accurate meniscus reading and minimises parallax error. Offered in packs of 2 pc(s), the burette originates from manufacturer Witeg in Germany. It is well suited to acid-base, precipitation and redox titrations, reagent standardisation and general quantitative chemistry in research, quality-assurance and teaching laboratories. The two-way stopcock configuration allows convenient filling and dispensing operations on conventional burette stands, while the Schellbach design supports reliable endpoint detection with colourless or pale solutions under normal laboratory lighting.

Questions about BURETTES,CLASS B,25 ML:0,05 WITH TWO-
What is this article?
BURETTES,CLASS B,25 ML:0,05 WITH TWO- is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Buretten, inside Volumetrisch glaswerk, in Labmateriaal.
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.
