Description
Schellbach burette with stopcock and key 100 ml is a class B volumetric instrument designed for precise titration work in analytical and teaching laboratories. It features the classic Schellbach stripe that enhances meniscus readability against a contrasting background, thereby minimising parallax errors during volume measurement. A straight stopcock fitted with an NS glass key provides reliable, leak-free control of titrant flow. The 100 ml capacity meets class B accuracy requirements for routine quantitative analysis. Net weight is 0,113 kg per unit. Offered in packs of 2 pieces from manufacturer Witeg, these burettes are suitable for educational settings, quality-control laboratories and general chemical analysis where class B tolerance is appropriate. The glass body and ground-glass key withstand repeated use with aqueous reagents and common titrants while remaining compatible with standard burette stands and clamps. Clear graduation and dependable stopcock performance support reproducible results in acid-base, complexometric and redox titrations without requiring the tighter specifications of class A glassware.

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