Description
Universal titration apparatus 25:0,05 ml class AS amber glass is a precision titration assembly designed for accurate volumetric work. The burette has a nominal capacity of 25 ml with 0,05 ml scale division and meets class AS tolerance requirements. It is equipped with a lateral valve stopcock fitted with a PTFE spindle for smooth, chemically resistant operation and is fabricated from amber glass to shield light-sensitive reagents. The complete apparatus includes a 2 l amber glass reservoir bottle and is supplied without a pressure bulb. Conformity-certified, the unit ensures traceable volume delivery for analytical and quality-control applications. Produced by manufacturer Witeg, the set is offered in packs of two pieces and has a net weight of 1,278 kg. The combination of amber glass, PTFE spindle and class AS accuracy makes this titration apparatus ideal for laboratories performing sensitive titrations that demand both chemical inertness and protection from photodegradation while maintaining straightforward daily handling on the laboratory bench.

Questions about Universal automatic burette 25:0,05 ml class AS
What is this article?
Universal automatic burette 25:0,05 ml class AS 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.
