Magnetic Stir Bars | Fisher Scientific
WEBMagnetic stir bars are stirrers or stirring hotplates used with magnets to mix a liquid or solution by creating a vortex. A number of factors affect magnetic stir bar efficiency and effectiveness, including its size, shape, and material.
WEBMagnetic stir bars are generally made of ALNICO (an alloy of aluminum, nickel, iron, and cobalt) magnets encapsulated in an FDA approved PTFE coating. In addition, magnetic stir bars also use high energy magnetic materials, such as Samarium Cobalt which increases strength of coupling with a drive magnet and
Mono-Mold Standard Stir Bar - Thermo Fisher Scientific
WEBMono-Mold magnetic stir bars are the standard all-purpose stir bar. Available with or without spinning rings; rings reduce contact area between stir bar and vessel, reducing friction and noise.

WEBAug 11, 2022 · When choosing a stir bar, the drive magnet, vessel shape, viscosity, and abrasiveness of the materials should be considered to ensure the correct size, shape and material of the stir bar is chosen to achieve effective and efficient stirring results.
WEB10-pack of most commonly used Octagonal stir bars with pivot ring in a variety of colors and sizes. Includes Spinbar® Restrainer to retain stir bars up to 80mm (3") against vessel walls while pouring.
Stir Bar Selection Guide - Fisher Sci
WEBA stir bar consists of two main components: the actual magnet and the coating. The materials for both can vary: Magnet. The magnetic component is usually made of ALCINO, an alloy of aluminium (Al), nickel (Ni), and cobalt (Co) that is suitable for most applications.
WEBSaturn Spinbar® Magnetic Stirring Bars easily stir powders into solutions without getting stalled. A prominent sphere in the middle of the bar elevates the stirring bar arms during rotation and consequently diminishes the surface contact area, permitting the magnet to spin freely without stalling.
WEBMagnetic stirring bars are generally made of ALNICO (an alloy of aluminum, nickel, iron and cobalt) magnets encapsulated in FDA approved Teflon®, known for its inert chemical compatibility and heat resistance.
WEBMagnetic stir bars are generally made of ALNICO (an alloy of aluminum, nickel, iron and cobalt) magnets encapsulated in an FDA approved PTFE coating. In addition, magnetic stir bars also use high energy magnetic materials, such as Samarium Cobalt which increases strength of coupling with a drive magnet and helps to reduce spinout when mixing
