Description
Pellet burette 25 ml class AS amber glass is a precision titration instrument for rapid volumetric analysis in analytical and quality-control laboratories. Graduated 25:0,05 ml and manufactured to class AS accuracy in accordance with ISO 385, the burette is built entirely from amber glass to protect light-sensitive titrants. It is equipped with a PTFE intermediate stopcock, a lateral valve stopcock and a PTFE spindle, ensuring smooth, chemically resistant operation during continuous use. The assembly includes a matching 2 l amber-glass reservoir bottle and is supplied without a pressure ball, supporting efficient Schilling-type pellet-burette workflows. Offered as a pack of two pieces from manufacturer Witeg, the system combines class AS metrological performance with robust PTFE sealing components. Amber glass construction of both burette and reservoir minimises photodegradation of reagents, while the PTFE fittings provide broad chemical compatibility. With a net weight of 1,272 kg, the compact unit is practical for routine bench-top titration, educational laboratories and standardised analytical procedures requiring reliable, light-protected delivery of standard solutions.

Questions about Pellet burette 25 ml class AS amber glass
What is this article?
Pellet burette 25 ml class AS amber glass is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labware.
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.
