This mixer is positioned for workflows that require continuous or intermittent overhead-style agitation, such as blending of suspensions, gentle mixing of reagents in sealed vessels, or preparation steps where disc-mounted holders are preferred. Associated categories include overhead shakers and overhead mixers, reflecting its role as a dedicated Überkopfmischer solution. The RES-RD 15 is included with the unit, so laboratories receive the complementary component needed for standard disc-mixer setups. Supplied as a single-piece package from manufacturer Phoenix Instrument, the RS-RD 20 is suited to bench-top installation in research, quality-control and teaching laboratories. Digital display feedback aids reproducible day-to-day operation once the included accessory is fitted. The configuration targets users who need a compact disc mixer with display and matching accessory already provided.

Questions about Disk mixer RS-RD 20
What is this article?
Disk mixer RS-RD 20 is the article on this page. Luminix Health distributes Phoenix Instrument for laboratory use. It sits in Stirring & mixing accessories, inside Stirring, shaking & mixing, in Lab instruments.
Stirring accessories are the bosses, the retort clamps and the spare knobs that hold an overhead stirrer over the vessel. The stand has to carry the motor's mass, not only the flask's.
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.
