Micro burettes according to Bang 10:0,02 ml are high-precision volumetric instruments for analytical titration requiring 10 ml capacity and 0,02 ml graduation. Fabricated from borosilicate glass 3.3 according to DIN EN ISO 385, the Class AS burettes are fast-draining and feature main-point ring graduation. They are adjusted to “Ex” and display blue graduation markings plus a Schellbach stripe for unambiguous meniscus observation. A straight stopcock with NS-PTFE plug is integrated in the drain cock and filling tube, combining smooth control with chemical resistance. Delivered as four pieces in a stable carton from manufacturer Marienfeld, these micro burettes serve quantitative analysis, quality-control and research laboratories that rely on Class AS performance. The PTFE stopcock, Schellbach stripe and blue scale together enable reproducible reagent delivery in micro-titration workflows. Borosilicate glass 3.3 construction ensures the dimensional stability and durability expected in routine laboratory volumetric work.

Questions about Microburettes acc. to Bang 10:0.02 ml,
What is this article?
Microburettes acc. to Bang 10:0.02 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.
