Description
DURAN® burette bottle with standard ground joint NS 29/32 is a clear 2000 ml replacement bottle intended for automatic burette systems. Fabricated from chemically highly resistant borosilicate glass 3.3, the vessel supports precise titrimetric procedures in which the previously unknown liquid volume required for titration can be read with high accuracy after the reaction is complete. Adjustment is performed to deliver (Ex) at a reference temperature of +20 °C, so that dispensed quantities correspond exactly to the scale because liquid adhesion to the glass was already taken into account during calibration. Volume tolerances meet the error limits of the relevant ISO and DIN standards. Supplied without accessories, this clear bottle from manufacturer Duran/DWK Life Sciences functions as a spare flask for automatic burettes. Typical laboratory applications encompass titration, volumetry and volumetric analysis, where chemical resistance, optical clarity and reliable volumetric performance are essential for reproducible results.
This article is part of Burettes, in Volumetric glassware.

Questions about DURAN® Burette Reservoir Bottle
What is this article?
DURAN® Burette Reservoir Bottle 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.
