Description
Class B burette 5 ml clear glass with straight stopcock and NS glass plug is a precision volumetric glassware item designed for accurate titration work in analytical laboratories. Featuring a capacity of 5 ml with 0,02 ml graduations, this clear-glass burette incorporates a straight stopcock fitted with an NS glass plug for reliable flow control and tight sealing during reagent delivery. The Class B tolerance ensures dependable performance for routine quantitative analysis, educational settings and quality-control procedures where high reproducibility is required. Manufactured from chemically resistant clear glass, the instrument allows unobstructed observation of the meniscus and liquid level. Supplied in a practical pack of 2 pieces from manufacturer Witeg, the burette is well suited for aqueous and many organic titrants commonly used in classical wet-chemistry methods. Its compact 5 ml volume makes it ideal for micro-scale or low-volume titrations while maintaining ease of handling and cleaning. The combination of straight stopcock geometry and NS glass key provides smooth operation and long service life under standard laboratory conditions.

Questions about Burettes, class B, 5 ml:0,02 straight s
What is this article?
Burettes, class B, 5 ml:0,02 straight s 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.
