Questions about Brush for flask, D=50mm, L=380mm
What is this article?
Brush for flask, D=50mm, L=380mm is the article on this page. Luminix Health distributes Bochem for laboratory use. It sits in Brushes & cleaning tools, inside Tools & accessories, in Matériel de laboratoire.
A laboratory brush reaches the inside of a burette, a flask or a tube that a cloth cannot enter. The bristle and the shape have to match the bore, or the brush becomes the thing that scratches the volumetric mark.
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.
