Description
Amber glass burette 25 ml with lateral valve stopcock and PTFE spindle is a precision volumetric instrument for accurate titration and quantitative analysis in analytical laboratories. The 25 ml capacity features a fine 0,05 ml graduation conforming to DIN-AS requirements and is supplied conformity-certified for reliable volumetric work. Manufactured from amber glass, the burette protects light-sensitive titrants and reagents during prolonged use. The lateral stopcock incorporates a PTFE spindle that ensures smooth, chemically resistant operation and precise drop control without glass-to-glass seizure. This model from manufacturer Witeg is well suited for routine and quality-control titrations where light protection and chemical inertness are essential. The unit is offered as a pack of two pieces, each with a net weight of 0,068 kg, making it convenient for equipping multiple workstations or teaching laboratories. Clear amber glass construction combined with the PTFE-spindle valve supports long service life under typical laboratory conditions while maintaining the accuracy demanded by DIN-AS standards.

Questions about Burettes, DIN-AS 25 ml:0,05 lat. valve-
What is this article?
Burettes, DIN-AS 25 ml:0,05 lat. valve- 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.
