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 (6, 12, 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, syringes and bottles
With the right type of stir element we can also stir the same vessels using our VP 710 series Tumble Stirrers.
