Description
Burettes class B with lateral valve stopcock in clear glass offer a 50 ml capacity graduated at 0,1 ml intervals for accurate volumetric work in titration and quantitative analysis. The side-mounted valve stopcock incorporates a PTFE spindle that ensures smooth, controlled delivery and good chemical resistance during routine laboratory use. Clear glass construction permits unobstructed observation of the meniscus and liquid column, supporting reliable endpoint determination in analytical chemistry, quality control and teaching laboratories. These burettes are supplied as a pack of 2 pieces from manufacturer Witeg and are well suited to standard aqueous titrants and many common reagents. The lateral stopcock arrangement improves handling convenience when the instrument is mounted on a stand, while the class B tolerance meets everyday precision requirements without unnecessary over-specification. Net weight is 0,07 kg, making the units easy to position and store. They integrate readily into existing titration setups and Schilling-type rapid-operation systems commonly found in educational and industrial labs.

Questions about Burettes, Class B, 50ml : 0,1, clear gla
What is this article?
Burettes, Class B, 50ml : 0,1, clear gla 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.
