Multi Stirrus SystemsTM

The Multi Stirrus Systems can be used as Vertical Tumble Stirrers, Lateral Vortex Tumble Stirrers and Conventional Magnetic Stirrers.   A Vertical Tumble Stirrer causes stir elements of all shapes and sizes to tumble end over end inside each of several vessels.   A Lateral Vortex Stirrer causes stir elements of all shapes and sizes to spin laterallly within each of many vessels.  A conventional Magnetic Stirrer causes one stir bar to spin horizontally in the center of a single bottle or vessel. The Multi Stirrus Systems are covered by USA Patent #6,176,609, USA Patent #7,484,880, European Union Patent #1,736,235 and German Patent #60 2006 026 122.5.   V&P Scientific's technology enables the user to use 3 different methods of mixing using the same machine.   A Multi Stirrus System can be used as Vertical Tumble Stirrer to mix samples in several, micro centrifuge tubes, test tubes, vials, syringes and  to keep particulates in suspension in syringes troughs and reservoirs..   A Multi Stirrus System can be used as a  Lateral Vortex Tumble Stirrer to mix many samples in micro centrifuge tubes, test  tubes, vials and syringes.  A Multi Stirrus System can also be used as a conventional Horizontal Stirrer to mix a single bottle or vessel.  Perhaps the best way to appreciate the how the Multi Stirrus Systems function is to see all the videos above this section.


Advantages of the Multi Stirrus Systems


  1. Can stir in any vessel regardless of the size or shape
  2. Can stir in syringes to keep bar coded beads in suspension for drop seq assays
  3. Complete stirring of large numbers of samples
  4. Can stir chemical reactions to speed completion
  5. Can run multiple experiments in parallel
  6. Will stir even 100,000 centistoke viscous solutions (6.6 times more viscous than honey)
  7. Will stir even thick slurries and emulsions
  8. Simple to operate, full speed control
  9. Can set exact RPM for reproducible results day to day
  10. Designed to be compatible with most robotic systems
  11. Flexibility of stir deck alignment
  12. Custom designs are not a problem
  13. Available in 110 volt and 220 volt (CE compliant) versions

Two Models available

Using the most powerful permanent magnets manufactured, we make two Multi Stirrus models to fit the many varied applications and requirements of our customers.   The second model (VP 710N or NanoStirrus) is smaller than the VP 710D3.   Please check with our knowledgeable staff to help you make the appropriate model and accessory selection for your application. Our specialty is flexibility- let us know if you have a custom application today!

Stir Elements designed for Vertical Tumble Stirring

We offer a large assortment of magnetic Stainless Steel Stir Elements from Stir StiXs to Discs to bars and dowels to fit into any well, vial, tube or syringe.  Check out the Stir Element page for more information on coatings and dimensions.

We also sell Alnico and Rare Earth Magnetic Stir Bars.

Multi Stirrus Mixing of Viscous Solutions

The ability to stir extremely viscous solutions, slurries and emulsions is a very useful characteristic of the V&P Multi Stirrus System Stirrers.  Our Multi Stirrus System Stirrers and Stir Elements have the ability to mix even solutions of 100,000 centistokes (6.6 times more viscous than honey).
