Description
DURAN® burette alone with side arm, Class AS, 25 ml is a precision volumetric glassware component intended for titrimetric and volumetric laboratory procedures. It is manufactured from chemically highly resistant borosilicate glass 3.3, providing the chemical and thermal resistance expected of DURAN® laboratory glass. The nominal volume is 25 ml (0,025 l). Class AS accuracy supports dependable volume delivery where tight volumetric tolerances are required. The side-arm configuration facilitates connection into titration assemblies and related apparatus. Supplied as the burette alone from manufacturer Duran/DWK Life Sciences, the item is well suited as a modular or replacement element within existing titration setups. Application areas include titration, volumetric analysis and measure analysis in research, industrial quality control and teaching environments. The registered DURAN® mark identifies the established borosilicate glass 3.3 range used across analytical laboratories. Pack size is 1 piece. Robust glass construction together with Class AS grading supports consistent performance when the burette is used in accordance with standard volumetric practice.

Questions about DURAN® burette only, with side stopcock, class AS, 25 ml
What is this article?
DURAN® burette only, with side stopcock, class AS, 25 ml is the article on this page. Luminix Health distributes DWK Life Sciences 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.
