Beschrijving
Titration apparatus with Schellbach burette in borosilicate glass 3.3 is a complete volumetric setup for precise laboratory titrations. The conformity-certified unit combines a 50 ml Schellbach burette graduated at 0,1 ml with a 2-liter reservoir bottle. An intermediate stopcock fitted with NS-PTFE plug, lateral fine-dosing valve stopcock and PTFE spindle enables controlled reagent delivery and fine adjustment during endpoint determination. The Schellbach stripe improves meniscus readability against the clear borosilicate glass 3.3, which offers excellent chemical resistance and thermal stability for aqueous and many organic titrants. This apparatus from manufacturer Hecht is intended for analytical chemistry, quality-control and teaching laboratories that require repeatable volume delivery. The integrated bottle and stopcock assembly streamlines filling and reduces handling steps compared with separate burette and flask arrangements. Robust construction supports routine daily use while maintaining accuracy of the 0,1 ml scale divisions. Suitable for acid-base, redox and complexometric titrations where clear observation and reliable dosing are essential.

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 Labmateriaal.
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.
