Description
Burettes, class AS, with a straight glass cock are precision glass volumetric instruments for controlled liquid delivery in titration and related analytical work. This 50 ml model is made from DURAN® brown glass with white graduations, giving a clear scale against the amber body for confident volume reading during dispensing. Class AS designation suits quantitative laboratory tasks where reproducible delivery is required in chemical analysis, quality control and teaching environments. The straight glass stopcock allows direct manual flow control without an intermediate valve spindle. Brown glass construction is appropriate when light-sensitive titrants or reagents are handled on the bench or left on a stand between runs. Pack size is 2 pc(s), with a unit weight of 0,410 kg, supporting paired setups or spare capacity in busy liquid-handling stations. These glass burettes from manufacturer Hirschmann align with standard titration apparatus and glass burette workflows in the laboratory. White graduation markings remain legible for endpoint approach and volume recording. They integrate into existing liquid-handling protocols wherever class AS burettes with a simple straight glass cock are specified.
This article is part of Burettes, in Volumetric glassware.

Questions about Burette class AS With a straight glass stopcock, 50 ml
What is this article?
Burette class AS With a straight glass stopcock, 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.
