Description
Burettes according to Mohr 25:0,05 ml are precision class AS volumetric instruments intended for accurate titration and quantitative analysis. With a nominal volume of 25 ml and fine 0,05 ml graduation intervals, they support high-resolution delivery of titrants. Constructed from borosilicate glass 3.3, each burette is fitted with a straight stopcock and NS glass key for controlled flow and a reliable seal. A Schellbach stripe combined with blue graduation markings improves meniscus visibility and reading precision under laboratory lighting. These Mohr burettes from manufacturer Marienfeld are supplied packed two pieces per carton, ready for use in analytical chemistry, teaching laboratories and routine quality-control workflows. The robust borosilicate glass 3.3 material provides good thermal and chemical resistance for aqueous and many organic reagents. Class AS accuracy meets the demands of volumetric work where reproducible results are essential. The straight-stopcock design allows smooth, continuous delivery while the contrasting blue scale and Schellbach stripe facilitate confident endpoint determination during acid-base or redox titrations.

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 Burettes, inside Verrerie volumétrique, in Matériel de laboratoire.
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.
