Description
Burette with straight glass stopcock, class A, 25 ml is a precision volumetric glassware instrument for accurate titration and quantitative liquid delivery in the laboratory. Constructed from borosilicate glass 3.3 and designed according to ISO standard 385, it is adjusted to deliver (TD, Ex) and fulfils class A accuracy requirements at a nominal volume of 25 ml. The straight glass stopcock enables fine control of titrant flow for clear endpoints in acid–base, redox, and complexometric titrations. With a net weight of 0,133 kg and supplied as a single piece, the burette is practical for benchtop stands, teaching setups, and routine quality-control work. Borosilicate glass 3.3 provides robust chemical and thermal durability for repeated analytical use under typical laboratory conditions. A batch certificate is available free of charge as a download from manufacturer Labbox. Research groups, industrial QC teams, and educational laboratories that need ISO-compliant class A performance can rely on this burette for reproducible delivery and dependable volume measurement throughout extended titration series.

Questions about Burette with straight stopcock, class A, 25 ml
What is this article?
Burette with straight stopcock, class A, 25 ml is the article on this page. Luminix Health distributes Labbox 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.
