Description
Burette DIN-AS 50 ml with straight stopcock is a precision volumetric instrument intended for accurate titration and quantitative analysis in chemical and analytical laboratories. It offers a nominal capacity of 50 ml with fine 0,1 ml graduations and complies with DIN class AS accuracy requirements. The design incorporates a straight stopcock fitted with an NS glass key together with a Schellbach stripe that markedly improves meniscus visibility and reading precision under normal laboratory lighting. Clear glass construction ensures chemical resistance suitable for aqueous and many organic titrants used in routine acid-base, redox or complexometric determinations. Packaged as 2 pc(s) with a net weight of 0,094 kg, the burette is convenient for both teaching laboratories and quality-control benches. Produced by manufacturer Witeg and supplied with conformity certification (KB), it supports traceable volumetric work according to established glassware standards. The straight-stopcock geometry permits smooth, controlled reagent delivery while the Schellbach stripe reduces parallax error during endpoint observation. This combination of class AS tolerance, durable glass key and enhanced readability makes the burette a reliable choice for daily volumetric procedures requiring reproducible results.

Questions about Burette DIN-AS 50 ml straight stopcock
What is this article?
Burette DIN-AS 50 ml straight stopcock 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.
