Description
Burette class AS KB SB 25:0,05 ml with straight stopcock and PTFE plug is a precision volumetric glassware item manufactured from DURAN® borosilicate glass 3.3. Blue graduated and equipped with a Schellbach stripe plus main-point ring division, it provides a nominal volume of 25 ml and a scale division of 0,05 ml for accurate titration work. The instrument complies with DIN EN ISO 385, carries a declaration of conformity according to DIN 12600 and features dated batch identification for complete traceability. Its straight glass stopcock is fitted with a PTFE plug, ensuring smooth, grease-free operation and chemical resistance during repeated use. Offered in a pack of 2 pieces from manufacturer Hirschmann, these class AS burettes support reliable quantitative analysis in analytical chemistry, quality control and research laboratories. The Schellbach design markedly improves meniscus readability, while the robust borosilicate construction withstands typical laboratory thermal and chemical stresses. Ideal for routine and high-precision volumetric determinations where class AS accuracy is required.

Questions about BURETTES AS CC SB 25:0,05 ML, STRAIGHT STOPCOCK W. PTFE-KEY
What is this article?
BURETTES AS CC SB 25:0,05 ML, STRAIGHT STOPCOCK W. PTFE-KEY is the article on this page. Luminix Health distributes Hirschmann 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.
