Description
Burettes DIN class B 25 ml:0,05 with straight spindle stopcock and amber glass are precision titration instruments for analytical laboratories. Conforming to DIN class B, they feature a 25 ml capacity and 0,05 ml graduations for accurate volume measurement and delivery. The straight spindle stopcock provides smooth, controlled flow regulation during titrations. Amber (brown) glass protects photosensitive reagents from light-induced degradation while maintaining excellent visibility of the meniscus. Supplied as 2 pieces per pack from manufacturer Witeg, each burette has a net weight of 0,06 kg. These units are intended for chemical, pharmaceutical and educational environments that require dependable class B amber-glass burettes with spindle-type stopcocks. Suitable for integration into standard titration assemblies, Schilling-type rapid burettes and related volumetric apparatus, they combine mechanical reliability with light protection for consistent analytical performance.

Questions about Burettes DIN-B 25 ml : 0,05 with straig
What is this article?
Burettes DIN-B 25 ml : 0,05 with straig 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.
