Description
Titration apparatus in brown borosilicate glass 3.3 with intermediate stopcock is a Class AS volumetric instrument for precise laboratory titrations. Rated 50 ml with 0,10 ml graduation accuracy according to DIN EN ISO 385, it is conformity-certified and supplied with certificate together with a 2-litre bottle. The intermediate stopcock incorporates an NS-PTFE plug, a lateral fine-dosing valve cock and a PTFE spindle, enabling controlled reagent delivery and fine adjustment during endpoint determination. Brown glass protects light-sensitive titrants while the borosilicate glass 3.3 body offers chemical resistance and thermal stability for routine analytical work. This complete assembly from manufacturer Hecht supports quantitative analysis in chemical, pharmaceutical, environmental and teaching laboratories where certified volumetric glassware is required. The design facilitates reliable, reproducible titrations under standard laboratory conditions without additional adapters.

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 Matériel de laboratoire.
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.
