German quality with 3 year warranty

Powerful: The RZR Series can accomplish the most demanding tasks while providing the highest safety and increased performance life!

Safe: Motor switches off if high thermal load occurs; Sparkless motors; Electronic stirrers feature smooth start operation (preventing spills & splashing media); Speed ramps up slowly; Optional guard prevents contact with impeller shaft; Optional remote control via cable to start/stop electronic stirrer from outside closed fume hoods.

Reduced Cost of Ownership: 10 year average lifespan as sealed housing prevents internal corrosion while reducing maintenance/repair costs; Better mixing results in less time reduces process times significantly; Maintenance-free motors; Unique impeller technology mixes gels & other similar media in less time.

Accessories John Morris Scientific also has an extensive range of accessories for all the Heidolph overhead stirrers.
