Questions about Miniature Shaker KM 2
What is this article?
Miniature Shaker KM 2 is the article on this page. Luminix Health distributes Bühler for laboratory use. It sits in Shakers, rockers & rotators, inside Stirring, shaking & mixing, in Instruments de précision.
A shaker, rocker or rotator moves a rack, a plate or a bottle so the contents keep moving without a stirrer bar. Orbital, reciprocating and rocking motions are different. The platform, the load and the speed range are the specification.
Stirring keeps a mixture uniform or helps a solid dissolve. A magnetic stirrer spins a bar inside a closed vessel. An overhead stirrer drives a shaft when the liquid is viscous or the volume is large. A vortex mixer agitates a tube. A shaker moves a whole rack or a plate. The shape of the impeller and the speed decide whether the liquid turns over or merely spins. The vessels being stirred are indexed under ISO laboratory glassware.
