Questions about Aluminium chloride, basic hydrate, 25 % Al, 500 g
What is this article?
Aluminium chloride, basic hydrate, 25 % Al, 500 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Other lab tools & accessories, inside Tools & accessories, in Labware.
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.
