Description
Pellet burette 25 ml class AS amber glass is a high-accuracy titration device intended for rapid Schilling-style operation. It offers a 25:0,05 ml graduation range, class-AS tolerance and full conformity to ISO 385, all realised in amber glass that shields photosensitive solutions. The burette is equipped with an NS intermediate stopcock together with a lateral stopcock featuring an NS glass plug, providing precise dual-valve control. A 2 l amber-glass reservoir bottle completes the assembly, which is delivered without a pressure ball. Manufactured by Witeg, this configuration is ideal for analytical laboratories performing frequent volumetric determinations where both intermediate isolation and light protection are required. The NS glass-plug design ensures chemical resistance and long-term sealing integrity for a wide range of aqueous and organic titrants. Suitable for quality-control, research and teaching environments, the unit enables fast filling from the reservoir and accurate delivery while maintaining class-AS metrological performance throughout repeated titration cycles.

Questions about Automatic burettes, pellet, 25:0.05 ml,
What is this article?
Automatic burettes, pellet, 25:0.05 ml, 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.
