Description
Amber glass burette fabricated from borosilicate glass 3.3 featuring a straight NS stopcock with PTFE key delivers precise volumetric delivery for titration applications. Graduated to 50 ml with 0,1 ml increments and classified as class AS, the instrument includes a batch certificate supporting documented quality. Amber glass shields light-sensitive reagents while the white graduation markings remain clearly legible. The PTFE-keyed straight NS stopcock ensures chemically inert, drip-free operation and long service life under continuous laboratory use. This model from manufacturer Hecht is suited to analytical chemistry, pharmaceutical quality control and educational titration exercises where accuracy and light protection are essential. Borosilicate glass 3.3 provides high resistance to thermal shock and aggressive media. Supplied as 1 pc, the burette integrates directly into standard titration assemblies requiring reliable class AS performance.

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.
