Description
Burettes, class AS, with a straight valve cock are precision glass volumetric instruments for accurate liquid dispensing in titration and analytical liquid handling. This 10 ml model is manufactured from DURAN® brown glass with white graduations, offering a clear scale on the amber body for reliable volume observation during delivery. Class AS accuracy supports quantitative work in chemical analysis, quality control and instructional laboratories where small-volume titration demands careful control. The straight valve stopcock incorporates a PTFE spindle for smooth, corrosion-resistant flow adjustment during dispensing. Brown glass helps shield light-sensitive titrants while the burette remains in use or mounted on a stand. Pack size is 2 pc(s), and each unit weighs 0,345 kg, making the pair practical for parallel setups or reserve stock. These glass burettes from manufacturer Hirschmann fit standard titration apparatus arrangements and routine glass burette workflows. White graduation markings stay legible against the brown glass for endpoint approach and volume logging. They suit laboratories that specify class AS burettes with a straight valve cock and PTFE spindle for controlled 10 ml delivery.
This article is part of Burettes, in Volumetric glassware.

Questions about Burette class AS With a straight valve stopcock and a PTFE spindle, 10 ml
What is this article?
Burette class AS With a straight valve stopcock and a PTFE spindle, 10 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.
