The VP 706 Mega Stirrus was designed to meet those demanding stirring applications where a large volume of viscous material needs to be mixed. Previous lab stirrers just didn't have large enough or strong enough drive magnets get the job done. Our Mega Stirrus has a uniquely focused 30 cm long massive NdFeB drive magnet that creates a powerful attraction to stir bars in the vessel. Even liquids as viscous as 90% honey are easily stirred producing impressive vortex cones. See the vortex cone in the photo on the right. The other part of our secret to stirring large vessels with viscous material is our development of NdFeB stir bars. The stir bars couple so strongly to the drive magnet that no matter how thick or viscous the liquid is ... it will be stirred. These were invented and developed by us for stirring viscous material. We are the only source for NdFeB Stir Bars. See the patent pending technology behind these powerful stir bars at this link. |

The photographs to the right show the array of holes on top of the Mega Stirrus. Pins and posts are inserted into the holes to register and locate a vessel on top of the stir deck.

The Mega Stirrus comes in two models that are differentiated by the lowest speed they can spin drive magnet. When you are stirring very viscous material you must be able to stir at low speeds to maintain the couple of the drive magnet with the Stirring element.
The VP 706-1 is powered by a rugged 3/8 horse power AC inverter duty motor and operates at speeds from 30 to 300 RPM.
The VP 706-2 is powered by a brushless 90 watt flat motor (1/9 horse power) and operates at speeds from 100 to 450 RPM. |

The VP 706B-1 "Mini Stirrus" was developed to meet those stirring needs that require a strong drive magnet and greater speed and economy. The much smaller Mini Stirrus is shown on the right of the Mega Stirrus. The VP 706B-1 is powered by a 1/30 horse power DC brush motor and operates at speeds from ------ RPM. |
