Description
Pellet burette 50 ml class AS amber glass is a precision Schilling-type rapid-operation burette designed for accurate volumetric titration work. It provides a 50 ml capacity with 0,1 ml graduations and satisfies class AS tolerances according to ISO 385. The burette features a PTFE intermediate stopcock together with a lateral valve stopcock that incorporates a PTFE spindle, ensuring excellent chemical resistance and smooth control. A 2 l amber-glass reservoir bottle completes the assembly, shielding light-sensitive solutions. The unit is supplied without a pressure ball for straightforward laboratory handling. This configuration from manufacturer Witeg arrives as a pack of 2 pc(s) with a net weight of 1,284 kg. Full PTFE stopcock components combined with class AS accuracy and amber-glass construction render the burette particularly appropriate for analytical chemistry, quality-control titrations and extended series of quantitative determinations requiring both high precision and broad chemical compatibility.

Questions about Pellet burette 50 ml class AS amber glass
What is this article?
Pellet burette 50 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.
