Magnetic stirring bars provide effective stirring of samples via magnetic manipulation. Many models feature an octagonal shape with a central integrated pivot ring for optimal turbulence while stirring thanks to a greater surface area. The heavy-duty magnetic strips is one of the frequently used tools, strong enough to hold the solution. Commonly coated in Teflon to provide chemical inertness, occasionally glass will be the coating for use with most liquid alkali metals and alkali metal solutions in ammonia. Both of these coatings are inert and will not contaminate or react with the reaction solution.
Description:
3x1/2in. Teflon* PTFE. 8-sided profile for greater surface area and added turbulence when compared to the smooth surface of cylindrical bars. Molded pivot ring reduces friction and chattering. Powerful Alnico V magnet to achieve strong vortex.
Description:
Six octagon Spinbar Magnetic Stirring Bars, Teflon PTFE coated, with pivot ring. Contains two of each: (1" x 5/16") (11/2" x 5/16") (2" x 5/16").
Description:
Agitates liquids in round-bottom test tubes and flasks, where other stirring bars cannot be used. Maintains its position in vessel and will not wobble. DiameterxHeight: 7.5x9.5mm.
Description:
To hold stirring bar in place when pouring from beaker or flask by placing arrester against the bottom of the container. Arrester is 9.5mm (3/8") thick polyethylene, 51mm (2") diameter with a radial magnet.
Description:
Samarium Cobalt (Rare Earth) Magnet Encapsulated In Teflon PTFE, Rare Earth Magnets Provide Up To 3X The Coupling Strength Of Normal Alnico Magnets, which Minimize Decoupling While Stirring
Description:
Spinvane* Magnetic Stir Bar Fits 3 and 5ml Vials, Polytetrafluoroethylene-sheathed angled vanes featuring cross-mounted, built-in magnets, Canted face of the stirbar allows use in narrow conical-shaped tubes and sample vials
Description:
Spinwedge* Magnetic Stirring Bar, Polytetrafluoroethylene, 1/2inch x 1-3/4inch, Unique canted stirring face transfers torque efficiently, to ensure thorough blending of viscous solutions, Unique canted stirring face transfers torque efficiently.
