Description
Burette DURAN® class B with 25 ml nominal volume and 0,05 ml scale division is a precision volumetric glassware item designed for reliable titration and quantitative analysis in the laboratory. Fabricated from borosilicate glass 3.3, the clear-glass body carries permanent black graduations with line division and is fitted with a straight glass stopcock for controlled reagent delivery. The instrument conforms to DIN EN ISO 385 accuracy class B, making it suitable for routine analytical work, teaching laboratories and quality-control applications where class B tolerances are acceptable. Chemical resistance and thermal stability of the DURAN® borosilicate material support repeated use with aqueous solutions and many common laboratory reagents. Supplied in a practical pack of two pieces from manufacturer Hirschmann, this burette combines clear scale readability with robust construction for everyday volumetric tasks. The 25:0,05 ml configuration provides fine volume resolution while remaining easy to handle on standard titration stands, ensuring consistent performance across educational, industrial and research environments that require dependable class B glass burettes.

Questions about BURETTES CL. B 25:0,05 ML, STRAIGHT STOPCOCK
What is this article?
BURETTES CL. B 25:0,05 ML, STRAIGHT STOPCOCK 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.
