Description
Burettes with side arm, class B, DURAN® blue graduated, 25 ml : 0,05 are precision borosilicate glass tubes intended for accurate volumetric titration in analytical and educational laboratories. Fabricated from borosilicate glass 3.3, each tube carries permanent blue graduations with a scale division of 0,05 ml over the 25 ml nominal volume, ensuring clear meniscus reading during dispensing. An integrated side-arm stub of 8 mm diameter accepts the interchangeable stopcock number 890 10 76, allowing rapid assembly of complete Schilling-type or pellet burette systems. These class B tubes from manufacturer Hirschmann combine chemical resistance with thermal stability typical of DURAN® glassware, making them suitable for routine acid-base, redox and complexometric titrations. Supplied in packs of two pieces, the tubes support efficient laboratory stock management and parallel analytical workflows. Their robust construction maintains graduation integrity under repeated handling while remaining compatible with standard titration apparatus configurations used in quality-control and teaching environments.

Questions about BURET WITH STEM,CL.B,DURAN, BLUE GRADUATION 25 ML : 0,05
What is this article?
BURET WITH STEM,CL.B,DURAN, BLUE GRADUATION 25 ML : 0,05 is the article on this page. Luminix Health distributes Hirschmann 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.
