Titration apparatus according to Pellet 25:0,05 ml is a class AS volumetric device designed for reliable titration procedures in analytical and quality-control laboratories. Constructed from borosilicate glass 3.3 and conforming to DIN EN ISO 385, it offers the chemical resistance and dimensional stability needed for everyday volumetric work. Features include automatic zero-point adjustment, a Schellbach stripe for improved meniscus visibility, and blue graduation marks at 0,05 ml intervals across the 25 ml nominal volume. An NS PTFE stopcock is fitted in the drain valve; the apparatus is supplied without intermediate stopcock, bottle or blower. This Pellet-type unit from manufacturer Marienfeld arrives packed two pieces per carton and is appropriate for acid-base, redox and complexometric titrations. Its standardised accuracy class and practical design make it a dependable choice for research, industrial and teaching environments requiring reproducible volume measurement.

Questions about Automatic burettes acc. to Pellet 25:0.05 ml
What is this article?
Automatic burettes acc. to Pellet 25:0.05 ml is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Burettes, inside Volumetric glassware, 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.
