Dimensions (L x Ø): 50 x 8 mm Made of a highly magnetic material (rare earth samarium-cobalt), it allows for greater torque than with conventional stir bars. The PTFE coating is chemically inert and resistant to aggressive chemicals Optimum mixing in vessels of greater volume or in large graduated cylinders. May particularly be used in high-temperature applications and in the stirring of viscous liquids, soil samples, etc. Dimensions (L x Ø): 50 x 8 mm Made of a highly magnetic material (rare earth samarium-cobalt), it allows for greater torque than with conventional stir bars.
