Description
Pellet burette 50 ml class AS amber glass is a precision Schilling-type rapid-operation burette intended for accurate volumetric work in titration. It delivers a 50 ml capacity with 0,1 ml graduations and meets class AS tolerances in accordance with ISO 385. The assembly comprises an NS intermediate stopcock, a lateral stopcock and an NS glass plug, together with a matching 2 l reservoir bottle, all fabricated from amber glass to protect light-sensitive media. Supplied without a pressure ball, the complete unit supports efficient filling and dispensing cycles typical of pellet and automatic burette systems. This configuration from manufacturer Witeg is delivered as a pack of 2 pc(s) and has a net weight of 1,29 kg. The amber-glass construction combined with class AS accuracy makes the burette suitable for quantitative analytical chemistry, quality-control titrations and routine laboratory determinations that require reliable volume delivery and light protection. Its intermediate and lateral stopcock arrangement allows controlled reagent flow while the large reservoir reduces the need for frequent refilling during extended series of analyses.

Questions about Automatic burettes, pellet, 50:0.1 ml, c
What is this article?
Automatic burettes, pellet, 50:0.1 ml, c 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.
