Beschrijving
Burettes according to Mohr 25:0,05 ml are class AS volumetric glassware designed for precise titrimetric work in analytical laboratories. Each burette offers a nominal volume of 25 ml with a fine 0,05 ml graduation, enabling accurate delivery and clear reading of dispensed volumes. Manufactured from KPG precision tubing of borosilicate glass 3.3, the clear-glass body carries a durable blue graduation and is adjusted at five points to ensure reliable volumetric performance. A straight stopcock fitted with an NS glass key provides controlled flow during titration. These Mohr burettes from manufacturer Marienfeld are conformity-certified and supplied with a batch certificate, documenting compliance with the accuracy requirements of class AS. Packed two pieces per carton, they are well suited for routine quantitative analysis, volumetric determinations and educational or research titration setups where reproducible class AS precision is required. The chemically resistant borosilicate glass 3.3 construction supports repeated use with aqueous and many organic titrants while maintaining dimensional stability and optical clarity for confident endpoint reading.

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.
