Burettes class AS KB SB 10:0,02 ml with straight valve stopcock and PTFE spindle are precision volumetric instruments made from DURAN® borosilicate glass 3.3. Blue graduated markings combined with a Schellbach stripe and main-point ring division ensure clear meniscus reading at a nominal volume of 10 ml and a scale division of 0,02 ml. Manufactured to DIN EN ISO 385 and accompanied by a declaration of conformity according to DIN 12600 together with dated batch identification, these class AS burettes deliver the accuracy required for quantitative titration. The straight valve stopcock fitted with a PTFE spindle provides smooth, grease-free and chemically resistant flow control. Supplied as a pack of 2 pieces from manufacturer Hirschmann, the burettes are ideal for analytical chemistry, pharmaceutical quality control and teaching laboratories performing precise volumetric analysis. The robust glass construction withstands typical laboratory reagents while the Schellbach design improves readability under varying lighting conditions. Nominal volume corresponds to 0,01 l, supporting reliable endpoint determination in routine and standardised titration procedures.
This article is part of Burettes, in Volumetric glassware.

Questions about BURETTES CL. AS CC 10:0,02 ML, SB STR.VALVE STOPC.PTFE SPINDL
What is this article?
BURETTES CL. AS CC 10:0,02 ML, SB STR.VALVE STOPC.PTFE SPINDL 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.
