Description
DURAN® burette alone with side arm, Class AS, is a precision laboratory burette for volumetric and titrimetric applications. Manufactured from chemically highly resistant borosilicate glass 3.3, it offers a nominal volume of 50 ml and is intended for accurate dispensing and measurement of liquids in analytical workflows. The Class AS accuracy rating aligns with the tight volumetric tolerances required for reliable titrations and volumetric analysis. The design includes a side arm for connection within titration setups, supporting controlled filling and delivery during routine laboratory use. This standalone burette body from manufacturer Duran/DWK Life Sciences is suitable where a separate burette tube with lateral arm is required rather than a complete automatic burette assembly. Borosilicate glass 3.3 provides high chemical resistance and thermal stability for everyday wet-chemistry work. Typical uses include titration, volumetry and quantitative volumetric analysis in research, quality control and teaching laboratories that specify Class AS glassware.

Questions about DURAN® burette only, with side stopcock, class AS, 50 ml
What is this article?
DURAN® burette only, with side stopcock, class AS, 50 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.
