Description
Class B burette clear glass with straight stopcock and NS glass plug, 25 ml is a clear-glass volumetric instrument designed for everyday titration tasks in analytical chemistry and laboratory training. Manufactured to accuracy class B, the 25 ml burette features a straight stopcock equipped with an NS glass plug for precise, controllable delivery of liquid reagents. The transparent glass body permits unobstructed observation of the meniscus and solution colour changes during endpoint determination. Each unit weighs 0,07 kg net and is supplied in packs of 2 pieces. These burettes from manufacturer Witeg are well suited to routine acid-base, precipitation and redox titrations where class B performance meets method requirements. The NS glass plug provides a reliable, re-greaseable seal that supports smooth stopcock action and easy cleaning after use. Clear-glass construction ensures compatibility with a wide range of aqueous and many organic titrants commonly encountered in teaching and quality-control laboratories. The compact pack size of two pieces facilitates convenient stocking for multiple workstations or student benches while maintaining consistent volumetric performance across the set.

Questions about Burettes, class B, with short line gradu
What is this article?
Burettes, class B, with short line gradu 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.
