Description
DURAN® Micro burette 5 ml, class AS, with Schellbach stripe and glass key is engineered for accurate micro-volumetric titration and measure analysis. Produced from chemically highly resistant borosilicate glass 3.3, the instrument is calibrated to deliver (Ex) at +20 °C reference temperature; after the 30-second waiting time the delivered volume corresponds exactly to the scale. Main-point ring graduation and the integrated Schellbach stripe facilitate precise meniscus observation, while the straight NS stopcock with glass key ensures smooth, controllable outflow. Volume tolerances meet accuracy class AS as defined by ISO and DIN. Each class AS burette bearing a batch number is accompanied by a batch certificate stating the measured mean, standard deviation and certificate date; batch certificates are additionally available online. Offered by manufacturer Duran/DWK Life Sciences, this 5 ml micro burette supports titration, volumetry and quantitative analytical procedures that demand reliable small-volume delivery. The durable borosilicate glass 3.3 body combines chemical resistance with optical clarity for dependable routine and research laboratory use.

Questions about DURAN® Microburette, Class AS, Schellbach stripe, glass key, CoC, batch certific
What is this article?
DURAN® Microburette, Class AS, Schellbach stripe, glass key, CoC, batch certific is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Burettes, inside Verrerie volumétrique, in Matériel de laboratoire.
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.
