Vortex Lateral Tumble Stirrer

     
 


V&P Scientific, Inc. has invented and built the world’s first VORTEX MICROPLATE MAGNETIC LATERAL TUMBLE STIRRER (USA Patent #7,484,880, European Union Patent #1,736,235 and German Patent #60 2006 026 122.5). Instead of tumbling a stir element in the vertical plane like our Alligator Tumble Stirrer, the Vortex Tumble Stirrer spins the stir elements by tumbling them laterally against a side wall of the vessel. This spinning motion produces a vortex cone in the liquid and efficiently mixes the contents of the liquid. This vortex cone is similar to the vortex cones produced by conventional horizontal magnetic stirrers however unlike the conventional horizontal stirrers which require a unique drive magnetic field under each vessel, the Vortex Stirrer because of its lateral wall tumbling action only requires one drive magnetic field to stir thousands of vessels. The Vortex Tumble Stirrers work best with round microwells, or round tubes, vials and bottles. The Vortex Tumble Stirrer causes stir elements of all sizes and shapes to tumble laterally and create a vortex cone inside each well. The Alligator Tumble Stirrer will stir all types of microplates (24, 48, 96, 384 and even 1536 wells). It will also stir V and U bottom microplates, PCR plates, micro-centrifuge tubes, test tubes, vials and bottles.   The only Stir elements that are not compatible with the Vortex Tumble Stirrer are the Stainless Steel Discs as the magnetic field in these stir elements is oriented through the diameter of the disc.  These discs will simply spin in the wells causing little stirring action.

We offer a large assortment of magnetic Stainless Steel Stir Elements from Stir StiXs 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 and Discs that are capable of stirring the most viscous liquids even honey.  Our Magnetic discs are magnetized through the thickness and consequently stand on end and Tumble laterally producing the most efficient vortex cones.

  Stir StiX Video Clip

     
 


A demonstration of the Tumble Stirrer using Stir StiXs to rapidly mix tall solutions of different specific densities in glass vials.  In this video we illustrate the ease and speed of a Vortex Stirrer "Tequila Sunrise" *(sucrose solutions of different color and density).  This Stir StiX method also has application in solubility studies and resolubilizing chemical libraries prior to testing.   Many compounds with poor solubility float on top the solution and so there is inadequate exposure to the solvent.  The Stir StiX passes through the solvent/compound interface and assures the maximum degree of solubilization.  More information about this new method of stirring can be found on the Stir StiX page.

  Vortex Lateral Tumble Stirrer - VP 708A

     
 

 

The Vortex Lateral Tumble Stirrer Model VP 708A is a triangle  measuring 30.5 cm on each side and 40 cm tall.  The Stir deck weighs 9 kg.

 

The VP 708A Vortex Lateral Tumble Stirrer simultaneously stirs 7 layers of 3 standard microplates - 21 total or 2,016 specimens in 96 well microplates, 8,064 specimens in 384 well microplates or 32,256 specimens in 1536 well microplates.  The VP 708A is capable of spinning the stir elements at speeds from 40 to 1550 RPM.  The high speed vortex action is great for many applications especially if you want to stir the contents of deep well microplates.  The ability to turn the stir elements over 1550 RPM in the same direction, creates significant fluid movement. This fluid movement and the physical interaction with the stir elements is ideal for resuspending dried extracts, mixing viscous reagents and keeping organisms or beads in suspension in deep well microplates. 

 

This model also is available in a CE compliant version (VP 708ACE).   The designation "CE" on the catalog number of stirrers indicates the international version designed to operate on 230 Volts at 50 hertz. 

 

All of the motors and controls used in the Vortex Lateral Tumble Stirrer are rated for continuous rugged usage and are maintenance free.  If you need to stir for long periods of time, this system won't quit on you.

 
 
 


Flexibility of design

     
 


The platters that the microplates rest on can be reconfigured to adapt to plates or racks of different heights by simply adding or subtracting spacers.  The photo to the right illustrates the Vortex Lateral Tumble Stirrer configured to stir midi deep well blocks, standard microplates and test tubes.

 
 
 


The photo to the right illustrates the Vortex Lateral Tumble Stirrer configured to stir 12 deep well blocks.

VP 708A-L-PLATTER

     
 


One customer had an application that required mixing and being able to visually monitor the bottom his plates while mixing.  Our solution was the
VP 708A-L-PLATTER
with a nest that is cut in the platter to hold the edge of a microplate and a rectangular hole to expose the bottom surface of the plate for a variety of optical probes to access the bottom surface.

 
 
 


The number of VP 708A-L-PLATTERs to use will depend on the requirements of the optical sensors used.  The photo on the right illustrates the flexibility of construction design.  Just add or subtract spacer rings to increase or decrease the distance between the platters.

 
 


 
**NEW** Super Vortex Lateral Tumble Stirrer - VP 708S

 
 


The VP 708S Vortex Lateral Tumble Stirrer can hold more microplates and simultaneously stirs 9 layers of 4 standard microplates - 36 total or 3,456 specimens in 96 well microplates, 13,824 specimens in 384 well microplates or 55,296 specimens in 1536 well microplates.  The VP 708S is capable of spinning the stir elements at speeds from 40 to 1550 RPM.  The high speed vortex action is great for many applications especially if you want to stir the contents of deep well microplates.  The ability to turn the stir elements over 1500 RPM in the same direction, creates significant fluid movement. This fluid movement and the physical interaction with the stir elements is ideal for resuspending dried extracts, mixing viscous reagents and keeping organisms or beads in suspension in deep well microplates. 

 

The larger magnetic cylinder of the VP 708S produces a magnet flux field that extends farther than the VP 708A thus it facilitates the stirring of much more viscous solutions.

 

This model also is available in a CE compliant version (VP 708SCE).   The designation "CE" on the catalog number of stirrers indicates the international version designed to operate on 230 Volts at 50 hertz. 

 

All of the motors and controls used in the Vortex Lateral Tumble Stirrer are rated for continuous rugged usage and are maintenance free.  If you need to stir for long periods of time, this system won't quit on you.

  Umbrella Stirrers - VP 772FNU-24

     
 


The newest of our innovations in stirring in microplates are the Umbrella Stirrers
VP 772FNU-24
.  The Umbrella Stirrers are constructed out of PTFE with our unique sandwich pockets for the magnets positioned above the support plate to keep the stirrer from touching the bottom of the microplate.   These Umbrella Stirrers allow for mixing in 24 well microplates without touching the bottom or sides of the wells.  Thus cells or other objects on the bottom of the wells will not be damaged or disturbed when new compounds or reagents are added to the wells and mixed.  These stirrers are capable of mixing solutions as viscous as 90% honey.  See video

 

This system can also be used to mix magnetic beads as the stirrer's magnet is not in contact with the liquid.

 

These stirrers are designed to only work with our VP 708 series Vortex Stirrers.

The Umbrella system consists of an autoclaveable polycarbonate support plate
VP 772FNU-24P with 24 holes to accommodate the VP 772FNU-24 Stir Elements see arrow.  The microplate lid fits on top of this support plate.

 

This type of stirrer can also be custom made for 48 and 96 well microplates.
