Beschrijving
Water decomposition apparatus according to Hoffmann is a classic laboratory glassware system for demonstrating the electrolysis of water. It consists of a glass part with two parallel tubes graduated 0-80/1/5 ml, the zero point located in the stopcock fitted with a rubber stopper, two carbon electrodes and a metal stand. This complete assembly from manufacturer Witeg enables clear visual observation and volumetric measurement of the hydrogen and oxygen gases evolved during electrolytic water decomposition. The parallel-tube design supports simultaneous collection of both gases, allowing direct comparison of volume ratios in teaching and experimental settings. With a net weight of 3,45 kg the apparatus is supplied as 1 pc and is well suited for chemistry education, demonstration of Faraday’s laws and basic electrochemical experiments. The graduated scale on the tubes permits quantitative evaluation of gas volumes, while the stopcock and rubber stopper ensure controlled sealing during operation. Robust construction with carbon electrodes and metal support makes the unit practical for repeated classroom or laboratory use with aqueous electrolytes.

Questions about Water decomposition apparatus acc. Hoffmann
What is this article?
Water decomposition apparatus acc. Hoffmann is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Overige labgereedschappen & accessoires, inside Gereedschap & accessoires, in Labmateriaal.
This shelf is the bench tools that do not belong to a narrower rack: odd holders, small aids, pieces that complete a setup. The useful check is what the tool touches, and whether that contact adds a contaminant.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
