VP 772BP-N42-11-23

Magnetic Stir Bar for Bottles, Beakers, Flasks, and Graduated Cylinders, PVDF Encapsulated NdFeB Magnets, 42 MGO, Autoclavable, 150°C Maximum Operating Temperature, 11.5mm Diameter x 23.1mm Length, 10/pkg

The VP 772BP-N42-11-23 is a PVDF encapsulated Stir Bar, used to stir various sizes of bottles, beakers, flasks and graduated cylinders. These stir elements work best with our Conventional Stirrers. This Stir Bar can be used with containers that have a neck opening of 11.5mm and larger. Combined with V&P Scientific's Conventional Stirrers the Stir Bar can mix solutions as thick as honey (10,000 cps). *Also available in PEEK encapsulation (VP 772BK-N42-11-23) and a more power magnet (VP 772BP-N52-11-23).

NdFeB Encapsulated PVDF Magnetic Stir Bars and Discs

Neodymium Iron Boron (NdFeB) is the strongest (52 MGO) 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 (52 MGO) and a low (42 MGO) strength magnet. The low strength (42 MGO) magnets are more temperature resistant (150°C) and can be autoclaved for sterility purposes while the high strength (52 MGO) magnets are inactivated at 80°C.  Please note that PVDF is only heat stable to 140C while the NdFeB is stable to 150C.  So you need to select your magnets and encapsulation material with your application requirements in mind. 

 

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. If your application requires a different diameter, let us know.

 

The VP 772DP-N42-24-3 (24 mm diameter x 2.9 mm thick) PVDF encapsulated disc was designed to fit into many vials. If your application requires a different diameter, let us know.

 

If your application entails grinding to make nano particles you may also want to use our abrasive resistant and more temperature resistant PEEK encapsulated NdFeB or SmCo.  See this URL for a chemical resistance guide for PVDF and PEEK. http://www.vp-scientific.com/images/plastic_chem_resist_guide/Plastics%20Intl%20Chemical%20Resistance%20Guide(2).pdf
