Description
Titration apparatus in brown borosilicate glass 3.3 provides a light-protected volumetric system for sensitive titrations. The conformity-certified assembly includes a class AS burette of 10 ml capacity with 0,02 ml graduation, manufactured to DIN EN ISO 385 and supplied with certificate. A 2-liter bottle is connected via an intermediate stopcock featuring an NS-PTFE plug, lateral fine-dosing valve stopcock and PTFE spindle for precise reagent control. The brown glass protects light-sensitive solutions while retaining the chemical resistance and thermal properties of borosilicate glass 3.3. This complete unit from manufacturer Hecht is designed for analytical laboratories performing accurate volumetric work under reduced light exposure. Class AS tolerances ensure high metrological reliability for quantitative analysis. The integrated fine-dosing valve supports careful approach to the endpoint, and the PTFE components minimise contamination and sticking. Suitable for pharmaceutical, environmental and research applications requiring both precision and protection of photosensitive titrants.

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.
