Description
Class B burette 25 ml clear glass with removable PTFE stopcock is precision volumetric glassware intended for accurate liquid dispensing in titration and quantitative analysis. With a nominal capacity of 25 ml and fine 0,1 ml graduations, the clear glass body allows clear meniscus observation for reliable volume readings during routine laboratory work. The removable PTFE stopcock offers chemical resistance, smooth flow control and straightforward cleaning or replacement when required. Supplied in a pack of 2 pc(s) and weighing 0,056 kg net, these instruments meet class B tolerance expectations for educational, quality-control and general analytical environments. Produced by manufacturer Witeg, the burettes suit acid-base, redox and complexometric titrations as well as other volumetric procedures that demand controlled delivery. The combination of transparent glass construction and a detachable PTFE stopcock supports both durability and practical maintenance in busy laboratory settings where consistent performance and ease of handling are essential.

Questions about Burettes, Class B, 25ml : 0,1 with new
What is this article?
Burettes, Class B, 25ml : 0,1 with new 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.
