Description
Burette tube class B Schellbach 50 ml is a precision glass replacement component intended for volumetric titration assemblies in analytical laboratories. The tube is graduated in 0,1 ml increments and conforms to class B tolerance, incorporating the characteristic Schellbach stripe that improves meniscus visibility against the scale. It serves as a spare or exchange part for existing burette systems requiring accurate volume delivery. This item from manufacturer Witeg is supplied in packs of 2 pc(s) and has a net weight of 0,062 kg. The Schellbach design places a vertical blue line on a white background, allowing clearer reading of the liquid level under typical laboratory lighting. Suitable for educational settings, routine quality-control work and general chemical analysis where class B accuracy is sufficient, the tube supports consistent titrant dispensing once fitted into a complete burette. Durable glass construction withstands normal laboratory handling and cleaning procedures. Facilities can maintain titration equipment economically by replacing only the tube rather than the entire instrument, ensuring continued reliability in volumetric procedures.
This article is part of Burettes, in Volumetric glassware.

Questions about Burette-tube, class B, Schellbach, 50 m
What is this article?
Burette-tube, class B, Schellbach, 50 m 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.
