  • Stir Bars & Stir Bar Retriever

    The magnetic stir bar withstands temperatures up to 250°C, making them suitable for use with both unheated and heated stirrers. The Stir Bar Retriever is encapsulated in PTFE making it easy to clean and durable. Made from ALNICO, one of the strongest permanent magnets available The sintered...

  • Color Octagon Spinbar® Magnetic Stir Bars

    Octagon magnetic stirring bars with integral pivot ring are the most commonly used shape. Choose from red, yellow or blue. Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon® PTFE low friction coating; durable and inert Interrupted profile provides greater surface area and added...

  • Octagon Spinbar® Magnetic Stir Bars

    Bel-Art - SP Scienceware

    Octagon magnetic stirring bars with integral pivot ring are the most commonly used shape. Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon® PTFE low friction coating; durable and inert Interrupted profile provides greater surface area and added turbulence when compared to the smooth...

  • Polygon Spinbar® Magnetic Stirring Bars (without Pivot Rings)

    These stir bars have polygon multifaceted surfaces that add turbulence relative to similar smooth size cylindrical bars. Alnico magnet encapsulated in FDA Grade, USP Class VI Teflon® PTFE low friction coating; durable and inert Manufactured in a registered ISO 9001:2008 facility, as verified by...

  • Micro (Flea) Spinbar® Magnetic Stirring Bars

    Micro (Flea) magnetic stirring bars are designed for stirring small volumes in vessels such as vials, tubes and gradient makers. Particularly useful for environmental testing and life science applications in which small sample volumes need to be prepared and evaluated Alnico magnet encapsulated in...

  • Cylindrical Stir Bars

    Globe Scientific

    Produced from PTFE For the stirring of liquids on magnetic stirrers and/or hotplate stirrers Strong alloy magnets sheathed in pure white inert PTFE Supplied in polarity aligned packs to ensure maximum coupling strength Resistant to virtually all chemical attack and temperatures up to 260°C

  • Stir Bars, Octagonal

    Our stir bars feature ALNICO V magnetic cores which are one of the most powerful permanent magnet alloys available. Stir bars should not be stored in a random mass, or dropped on a hard surface especially steel. Stir bars should be stored in pairs to maintain magnetic strength.

  • Stir Bar Retrievers

    Globe Scientific

    Magnet permanently embedded in PTFE rod Ideal for retrieving magnetic stirrer bars from particularly sensitive or corrosive liquids

  • Micro Stir Bars

    Globe Scientific

    Produced from PTFE For use in small vessels, e.g. test tubes, vials, etc.

  • Pivot Ring Stir Bars

    Globe Scientific

    Produced from PTFE Central pivot ring ensures efficient spinning, even on curved or uneven bases

  • Cylindrical Spinbar® Magnetic Stirring Bars

    Cylindrical magnetic stirring bars offer excellent centering and smooth running characteristics. Small removable pivot ring in the center adds to their versatility Pivot ring minimizes the contact area of the bar to the vessel, reduces friction and lessens marring of plastic containers Alnico magnet...

  • Polygon Spinbar® Magnetic Stirring Bars

    These stirbars have polygon multifaceted surfaces that add turbulence relative to similar smooth size cylindrical bars. Center molded pivot ring minimizes the contact area between the bar and the vessel; reduces friction and chattering Marring of plastic containers is diminished Alnico magnet...

  • Scienceware® Stirring Bar Retrievers

    Easily recover stirring bars from containers using the Spinbar® Magnetic Retriever. Offered in two different lengths (12" and 18"), each retriever has a polyethylene rod, 9.5 mm diameter, with Alnico magnet sealed in one end and loop on opposite end.

  • Elliptical (Egg-Shaped) Spinbar® Magnetic Stirring Bars

    These egg-shaped stirring bars are designed especially for use in round-bottom vessels as they spin unrestricted by the vessel contour. Particularly well suited for round bottom flasks; shape ensures complete mixing Offers minimal contact when used in plastic containers Egg shape provides pivot...

  • Rare Earth – Samarium Cobalt Spinbar® Octagon Magnetic Stirring Bars

    Reduce frequency of spinout in viscous solutions or when stirring at high speeds. The high magnetic field strength of Samarium Cobalt (Rare Earth) magnets can provide up to three times stronger coupling vs. Alnico magnetic stirring bars.  Stronger coupling with the drive magnet keeps the...

  • Magnetic Stir Bar Retriever

    The Corning stir bar retriever contains a strong magnet to remove a stir bar from all glass and plastic containers used in the laboratory. The container must be taken off the magnetic stirrer before using the retriever as the high-powered magnet in the stirrer cancels out the one in the retriever....
