Description
Amber glass burette DIN class AS 50 ml with lateral valve stopcock and PTFE spindle is a high-precision volumetric tool for titration and quantitative laboratory work. It provides a 50 ml capacity with 0,1 ml graduation intervals and meets DIN class AS accuracy specifications. The amber glass body shields light-sensitive reagents from photodegradation during use and intermediate storage. A lateral valve stopcock combined with a PTFE spindle delivers smooth, chemically resistant flow control and reliable sealing. Each unit is conformity-certified for documented laboratory compliance. Offered as a pack of two pieces from manufacturer Witeg, this burette is well suited for analytical chemistry, pharmaceutical quality control, environmental testing and educational titration exercises. The PTFE spindle enhances chemical compatibility and reduces the risk of seizing compared with all-glass keys. Net weight is 0,08 kg. Its robust construction and precise graduation support reproducible results in both aqueous and many organic titration media, making it a practical choice for daily laboratory workflows requiring dependable volume delivery.

Questions about Burettes, DIN-AS 50 ml:0,1 lat. valve s
What is this article?
Burettes, DIN-AS 50 ml:0,1 lat. valve s 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.
