European Patent Issued for V&P Scientific, Inc.'s "Vortex Stirring of Vessels in a Two-Dimensional Array"

Published: Mar 15, 2012

SAN DIEGO, CA – November 30, 2011 – V&P Scientific, a developer of scientific research equipment, today announced that the European Patent and Trademark Office issued a patent for its method of vortex stirring. European Patent No. 1736235 entitled, “Vortex Stirring of Vessels in a Two-Dimensional Array” protects the Company’s use of the invention of mixing the contents of a two-dimensional array of vessels by causing magnetic stir elements within the vessels to tumble in response to the rotation of magnetic flux lines. The patent is owned by V&P Scientific, Inc.

This patent solidifies V&P Scientific’s intellectual property position in the stirring and mixing industries of Switzerland, Germany, and the United Kingdom. V&P Scientific also owns the same patent in the United States, US Patent No. 7,484,880 B2. The advantage of the V&P Scientific stirring product line is the ability to stir viscous material in multiple small and large vessels simultaneously, the ability to stir at low and fast speeds, the ability to create impressive vortex stirring cones, the ability to accommodate containers of all sizes, and the ability to fit any specific application on the bench top or on robotic platforms.

About V&P Scientific. V&P Scientific, Inc. was founded in 1979 and has 12 patents around the world. The company’s revolutionary technology is based on work developed by in-house scientists and engineers in collaboration with a customer base in “cutting edge” companies. V&P Scientific invented the Alligator Tumble Stirring System and the Vortex Stirring System to magnetically mix in microplates, vials, tubes, bottles, and syringes. The products are designed to meet those demanding stirring applications where large or small volumes of viscous material must be mixed. The massive Neodymium Iron Boron drive magnet creates a powerful attraction to stir bars in the vessel that previous lab stirrers were not strong enough to mix.
