Questions about Rocker 420 oil free compressor, maintena
What is this article?
Rocker 420 oil free compressor, maintena is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Shakers, rockers & rotators, inside Stirring, shaking & mixing, in Instruments de laboratoire.
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.
