Beschrijving
Burettes according to Mohr 25:0,05 ml are precision volumetric instruments intended for accurate titration work in analytical laboratories. Made from borosilicate glass 3.3, these class AS burettes feature a straight stopcock with an NS PTFE plug for smooth control, chemical resistance and reliable sealing during delivery. Blue graduation combined with a Schellbach stripe enhances meniscus readability, supporting precise volume measurement at 0,05 ml intervals across the 25 ml nominal capacity (0,025 l). The robust glass construction is suited to common laboratory reagents and routine analytical handling. Supplied in cartons of two pieces from manufacturer Marienfeld, the burettes meet class AS accuracy requirements for quantitative analysis. They are well matched to acid–base, redox and complexometric titrations in research, quality-control and teaching settings where reproducible volumetric dispensing and clear scale visibility are essential for consistent results.
This article is part of Burettes, in Volumetric glassware.

Questions about Burettes acc. to Mohr 25:0.05 ml,
What is this article?
Burettes acc. to Mohr 25:0.05 ml, is the article on this page. Luminix Health distributes Marienfeld 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.
