Pellet burette 10 ml class AS amber glass is a laboratory titration instrument designed for rapid Schilling-style pellet-burette operation and precise volumetric work. Graduated 10:0,02 ml and conforming to class AS requirements according to ISO 385, it delivers reliable measurement performance for quantitative analytical procedures. The amber-glass construction protects light-sensitive titrants throughout filling, storage and dispensing. This variant is supplied without an intermediate stopcock and features a lateral valve stopcock with PTFE spindle, enabling smooth, chemically resistant control of reagent flow. A matching 2 l reservoir bottle supports continuous feed of the working solution, and the unit is provided without a pressure bulb. Net weight is 1,212 kg. Offered by manufacturer Witeg, the burette is well suited to teaching laboratories, quality-control suites and research facilities that require class AS accuracy together with amber-glass light protection. The compact pellet-burette format facilitates quick refill and emptying cycles characteristic of rapid-operation titration apparatus. Pack size is 2 pc(s), supplying a ready pair of instruments for parallel or backup use in acid–base, redox and complexometric determinations.

Questions about Automatic burettes, pellet, 10:0.02 ml,
What is this article?
Automatic burettes, pellet, 10:0.02 ml, is the article on this page. Luminix Health distributes Witeg 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.
