Description
Burette with lateral valve stopcock, amber glass, 25 ml is a precision volumetric glassware item designed for accurate titration work in analytical and quality-control laboratories. Manufactured to DIN requirements, it offers a 25 ml capacity with 0,05 ml graduations, enabling fine volume control during reagent delivery. The lateral valve stopcock incorporates a PTFE spindle for smooth, reliable operation and chemical resistance. Amber (brown) glass construction protects light-sensitive titrants from photodegradation while remaining fully transparent for meniscus reading. Supplied as a pack of 2 pieces from manufacturer Witeg, each unit has a net weight of 0,065 kg and is suitable for routine and specialised titration setups, including rapid-operation and Schilling-type assemblies. The robust glass body and PTFE components support repeated use with aqueous and many organic media. Ideal for pharmaceutical, chemical and educational laboratories requiring dependable amber-glass burettes with side-mounted valve control for efficient, light-protected volumetric analysis.

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