Description
Compact burette BLAUBRAND® AS brown glass with PTFE stopcock, 25 ml : 0,05 ml, Boro 3.3, DE-M is a high-precision laboratory instrument engineered for reliable titration and controlled liquid delivery. Constructed from durable borosilicate glass 3.3, the brown glass version shields photosensitive reagents from light-induced degradation. Class AS tolerance and a 0,05 ml subdivision provide the accuracy required for quantitative analytical procedures. An integrated PTFE stopcock guarantees smooth, chemically inert flow control without the need for grease, ensuring long-term leak-free performance with a wide range of solvents and titrants. Delivered as one piece and marked DE-M for verified conformity, the compact format reduces storage footprint while remaining suitable for conventional burette stands and rapid titration setups. This model from manufacturer Brand belongs to the BLAUBRAND® series and is well suited to routine and advanced work in chemical analysis, pharmaceutical quality control, environmental testing and teaching laboratories. The robust build withstands frequent handling and cleaning cycles typical of busy analytical environments.

Questions about Comp. burette PTFE stopc. BB AS amber gl, 25 ml:0,05 ml, Boro 3.3, DE-M
What is this article?
Comp. burette PTFE stopc. BB AS amber gl, 25 ml:0,05 ml, Boro 3.3, DE-M is the article on this page. Luminix Health distributes BRAND 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.
