Burettes class B SB 25:0,05 ml provide dependable volumetric performance for titration and quantitative analysis. Fabricated from DURAN® borosilicate glass 3.3, each unit features blue graduation, a Schellbach stripe and line division for clear meniscus reading. Nominal capacity is 25 ml with a scale interval of 0,05 ml; a straight glass stopcock allows precise flow control. The burettes comply with DIN EN ISO 385 and accuracy class B specifications, ensuring consistent results in routine laboratory workflows. Chemically robust borosilicate construction resists common aqueous reagents and mild solvents, while the Schellbach contrast band enhances readability under standard lighting conditions. Ideal for chemical, pharmaceutical, environmental and teaching laboratories that require standardised class-B glassware. Delivered as a two-piece pack from manufacturer Hirschmann, these burettes combine durability, standardised accuracy and straightforward handling for everyday volumetric work.

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