Description
Titration apparatus fabricated from brown borosilicate glass 3.3 offers a light-shielded solution for precise volumetric analysis. This conformity-certified system comprises a class AS 25 ml burette graduated at 0,05 ml according to DIN EN ISO 385 and delivered with certificate, together with a 2-liter bottle. The intermediate stopcock is equipped with an NS-PTFE plug, a lateral fine-dosing valve stopcock and a PTFE spindle, allowing accurate reagent addition and fine control near the titration endpoint. Brown glass protects photosensitive reagents while the borosilicate 3.3 material provides high chemical durability and thermal shock resistance. Supplied by manufacturer Hecht, the apparatus is intended for routine and high-accuracy work in analytical, quality-control and research laboratories. Class AS specification guarantees tight volume tolerances essential for quantitative determinations. The complete bottle-and-burette configuration simplifies setup and reduces transfer steps. Ideal for applications involving light-sensitive titrants where both metrological performance and optical protection are required.

Questions about Automatic burettes, borosilicate glass 3.3, Schellbach burette, conformity
What is this article?
Automatic burettes, borosilicate glass 3.3, Schellbach burette, conformity 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.
