Description
Replacement burette 50 ml with Schellbach stripe, class B is a quick-operating laboratory burette supplied as a spare or accessory part for volumetric analysis. It delivers a 50 ml capacity with 0,1 ml graduations, supporting controlled addition of titrant or reagent solutions. The Schellbach stripe provides an optical reference that sharpens meniscus observation and improves reading confidence. Packaged as 1 pc, the unit is intended for direct replacement within compatible quick-operating burette systems used in analytical chemistry. This accessory from manufacturer Witeg conforms to class B tolerance requirements and suits educational, research and quality-control laboratories performing routine titrations. The design enables rapid handling while preserving measurement reliability after original glassware is exchanged. Installation restores full operational capability without modification of existing methods. Originating from Germany, the burette integrates into conventional laboratory setups and assists consistent quantitative work where clear volume indication and class B performance are required.

Questions about Spare-burettes, class B, Schellbach, 50
What is this article?
Spare-burettes, class B, Schellbach, 50 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.
