PTFE Magnetic Stir Bars

These magnetic stir bars come in various shapes and sizes for stirring liquids on magnetic stirrers or hotplate stirrers. The oval bars are ideal for efficient stirring in round-bottomed flasks, and the wide range of cylindrical bar sizes is excellent for a broad array of flasks, cylinders, beakers, tubes, and more. The central pivot ring on the pivoting stir bars ensures efficient spinning, even on curved or uneven bases. The micro, or flea, bars are designed for stirring small volumes in vessels such as vials, tubes, and gradient markers. The stir bar set includes a total of 22 stir bars: (2) 12mm L x 4.5mm Dia., (2) 25mm L x 6mm Dia., (2) 45mm L x 8mm Dia., and (2) 60mm L x 9.5mm Dia. pivot ring bars; (2) 20mm L x 10mm Dia., (2) 25mm L x 12mm Dia., (2) 35mm L x 16mm Dia., and (2) 50mm L x 20mm Dia. oval bars; (3) 7mm L x 2mm Dia. and (3) 10mm L x 3mm Dia. micro bars.
