Description
Burette amber glass, borosilicate glass 3.3, straight NS stopcock with PTFE key, white is a precision volumetric instrument for titration work. Fabricated from borosilicate glass 3.3 in amber glass, the burette is white graduated and fitted with a straight NS stopcock that uses a PTFE key for smooth, chemically resistant operation. The 10 ml capacity is subdivided at 0,02 ml intervals and the instrument is classified as Class AS, supplied with a batch certificate. This amber-glass burette from manufacturer Hecht combines light protection of the amber body with the thermal and chemical durability of borosilicate glass 3.3. The straight NS stopcock with PTFE key ensures reliable flow control during quantitative titrations, while the white graduation markings remain clearly legible against the amber background. Delivered as a single piece, the burette is suited to analytical laboratories that require Class AS accuracy together with batch documentation. The combination of amber glass, precise 0,02 ml graduation and PTFE-keyed stopcock makes the unit appropriate for light-sensitive titrants and routine volumetric analysis where reproducible delivery of 10 ml volumes is essential.
This article is part of Burettes, in Volumetric glassware.

Questions about Burettes, amber borosilicate glass, white graduation, with interchangeable PTFE
What is this article?
Burettes, amber borosilicate glass, white graduation, with interchangeable PTFE is the article on this page. Luminix Health distributes Hecht 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.
