Multi Stirrus Systems^TM

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!
