Details V&P Stirrus Technology

Conventional Horizontal Magnetic Stirrers

The conventional horizontal Magnetic Stirrer technology has been around since 1944.  This system uses a motor to spin a drive magnet whose moving magnetic field connects with the magnetic field of a stir bar causing the stir bar to spin on a horizontal plane in a vessel above the drive magnet. V&P Scientific has improved that basic system.

Secrets Behind V&P Scientific’s Stirrus Technology

• The drive magnets in the V&P Scientific Stirrus machines use very large and very powerful (48 MGO) NdFeB rare earth magnets.  These are much physically larger and more powerful than the Alnico magnets (8 MGO) used in conventional horizontal stirrers.
• This means that V&P Scientific Stirrus machines project their magnetic field farther and form a stronger attachment to the Stir elements thus allowing them to stir very viscous solutions.
• V&P Scientific stir elements are made with powerful (48 to 52 MGO) NdFeB Rare Earth magnets and V&P is the only company to offer a full line of NdFeB stir elements to accommodate every vessel size.
• V&P is also the only source for 48 and 52 MGO NdFeB Stir elements.
• The extremely strong magnetic coupling/attraction between the V&P Scientific Stirrus drive magnet and the stir element enables stirring at high speed and in a viscous material.
• The motors in V&P Scientific Stirrus machines are very powerful and can maintain that power through both the low and the high speeds often required when mixing very viscous materials.
• Even liquids as viscous as 90% honey are easily stirred producing impressive vortex cones.
