The Spinvane® Angled Vane, Half Round Semicircular, Tapered Half Round Semicircular, the Spinring® Balancing Ring, the Spinfin® Finned and Double Finned are popular magnetic stir bar solutions for a variety of mixing needs.
The Spinvane® Angled Vane, Half Round Semicircular and Tapered Half Round Semicircular are good for narrow, conical shaped tubes. The Spinring® Balancing Ring keeps the stir bar centered, resists spinout and turbulent motion. The Spinfin® Finned and the Spinfin® Double Finned stirring bars work well in round bottom tubes and flasks.
Prices are for each, but volume pricing is available. Rose Scientific has a minimum order requirement, so it is important to inquire about volume purchases or to combine orders with the purchase of other equipment.
