Questions about RW 20 digital, Mechanical overhead stirrer
What is this article?
RW 20 digital, Mechanical overhead stirrer is the article on this page. Luminix Health distributes IKA for laboratory use. It sits in Overhead stirrers, inside Stirring, shaking & mixing, in Lab instruments.
An overhead stirrer drives a shaft from above, for volumes and viscosities a magnetic bar cannot move. Torque and speed range are the ratings. The chuck and the stand are part of using it. A high-speed disperser is a different head.
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.
