Neodymium Iron Boron (NdFeB) is the strongest of the permanent magnetic materials. Previously, Neodymium Iron Boron has not been available as a completely encapsulated Magnetic Stir Element. V&P is the only source of encapsulated NdFeB. We offer a high and a low temperature resistant form of the NdFeB which can be selected to fit your application. We also offer Samarium Cobalt (SmCo) rare earth magnets which are available for even higher-temperature applications. By way of comparison, Alnico magnets the most commonly used in magnetic stir bars, are much weaker at only 7 MGO. So if you need to stir viscous material, soil samples, wood chips, or particulates at high speeds or to grind nanoparticles with glass beads, this is the system for you. The disc design of the VP 772D series makes them significantly more efficient at moving liquid and thereby mixing solution in the tumble mode. Selecting a disc that is slightly smaller than the inside diameter of the vessel to be stirred results in the most efficient stirring. To stir viscous material requires greater energy so we constructed these discs from Neodymium Iron Boron and encapsulated them with PVDF to make them inert. The VP 772DP-N42-5-2 and VP 772DK-N42-5-2 (5 mm diameter x 1.7 mm thick) PVDF and PEEK encapsulated disc was designed to fit into 96 well microplates, deep well 96 well microplates and glass micro-tubes. The VP 772DP-N42-8-2 (8 mm diameter x 1.8 mm thick) PVDF encapsulated disc was designed to fit into many vials. Polyether ether ketone (PEEK) is a thermoplastic with excellent mechanical and chemical resistance properties that are retained through higher temperature applications. Because of these inherent properties, PEEK is an ideal material for use as a magnetic stir bar in high mechanical stress induced applications for its abrasion resistance or when chemical attacks are a concern. PEEK is much superior to PVDF in grinding applications or applications where glass beads or Zirconium Oxide beads are used to make nano particles.

Conventional PTFE Encapsulated Stir Elements (Stainless Steel, Alnico 7 MGO and Samarium Cobalt 29 MGO)


These stir bars can be used for both Tumble Stirring and Vortex Tumble Stirring applications as well as conventional horizontal spinning.    Whether you call them Magnetic Spinning Bars, Stirring Magnets or Magnetic Stir Bars we have one of the largest collections at the best prices. 

 

We also offer Alnico V and Samarium Cobalt magnets conventionally encapsulated in PTFE.  These stir bars and discs are shown in the photo to the right. In addition to the permanent magnet stirrers we also offer magnetic stainless steel Stir elements (discs, dowels and bars) and Stir StiXs.  The stainless steel stir elements are more cost effective and many of our customers treat them as disposables.  They are available uncoated, coated with cost effective parylene and encapsulated with PTFE.

 

V&P Scientific’s PTFE encapsulated Stir Elements are:

 

  • Isostatic encapsulated with PTFE to eliminate cracks and porosity
     
  • Use FDA approved PTFE
     
  • Contain Stainless Steel, Alnico V or Samarium Cobalt magnet cores
     
  • Have a polished finish to reduce pick-up and cross contamination
     
  • Can be sterilized using thermal or chemical means
     
  • Are high performance stirring bars at "disposable" prices
     
  • Our PTFE has a Broad range of chemical resistance see this URL http://www.vp-scientific.com/Chemical_Resistance_Chart.htm
  •  
  • Our stir bars range in diameter from 1.5 mm to 36 mm and from 2 mm to 165 mm in length.  The shapes also are diverse, from cylinders, rectangular, triangular, crosses, wing shaped, octahedral and discs.
