Description
Burettes, class B, with straight glass cock are glass volumetric instruments for measured liquid delivery in titration and general laboratory measuring methods. This 50 ml configuration is produced from DURAN® brown glass and features a white graduation that gives strong visual contrast for reliable meniscus reading. A straight glass cock governs outflow, enabling the user to move from rapid filling of the tip to fine dropwise addition near the endpoint. Brown glass construction supports work with light-sensitive reagents while maintaining the durability associated with DURAN® laboratory glassware. Supplied by manufacturer Hirschmann as a unit of 2 pieces, the pack suits titration stations that need matched instruments for parallel determinations, training courses, or environmental analysis workflows. Class B accuracy is appropriate for routine quantitative tasks that do not demand class A certification. The generous 50 ml capacity accommodates longer titrations and higher-volume methods without frequent refilling. White graduation on brown glass, combined with the straightforward stopcock design, yields a clear and robust tool that fits standard burette clamps and liquid-handling assemblies. Select this 50 ml class B brown-glass burette when larger capacity, light protection, and simple glass-cock control are required.

Questions about Burettes, class B, straight glass cock, DURAN®, brown glass, white grad., 50 ml
What is this article?
Burettes, class B, straight glass cock, DURAN®, brown glass, white grad., 50 ml 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.
