Description
Burettes DIN class B, amber glass, 25 ml provide reliable volumetric performance for titration and quantitative analysis. These class B instruments deliver a 25 ml capacity with 0,05 ml scale divisions, meeting DIN accuracy requirements for routine laboratory work. Each burette is fitted with a two-way stopcock and NS glass key (plug), allowing controlled filling and dispensing. Amber glass construction shields light-sensitive solutions from UV and visible light while permitting clear observation of the liquid level. Offered in a pack of 2 pieces from manufacturer Witeg, the units weigh 0,102 kg net each and are well suited to pharmaceutical, chemical and teaching laboratories. The combination of DIN class B tolerance, two-way glass stopcock and brown-glass body supports consistent results in standard and light-protected titration procedures, including pellet and rapid-operation burette systems. Durable glass construction ensures long service life under normal laboratory conditions.

Questions about Burettes DIN-B 25 ml:0,05 with two-way
What is this article?
Burettes DIN-B 25 ml:0,05 with two-way 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.
