Questions about Sleeves ST 45/40
What is this article?
Sleeves ST 45/40 is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Grease, boiling stones & sealants, inside Tools & accessories, in Labware.
Grease seals a ground joint. Boiling stones give a liquid a place to start boiling so it does not bump. A sealant does the same job as grease when grease would contaminate the product. They are small, and they decide whether a joint weeps.
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.
