A mechanical stirring device was attached to the aggregometer instead of the magnetic stir bar system. The PRP samples were stirred using a stirring rod tip that did not produce any magnetic fields in one channel of the aggregometer; in the other channel, a stirring rod carrying a small magnet at its tip was used. As a result, a magnetic field ...

Jun 06, 2019 With a magnetic stirrer, the stir bar size is also important. The stir bar should be roughly the same length as the internal drive magnet to prevent decoupling and spinout (when the bar loses its coupling and stops spinning altogether). When using a magnetic stirrer, note that there are often recommendations for maximum stir bar size.

This magnetic stirrer for spectroscopy uses a magnetic field to transmit torque to a Teflon coated magnetic bar inside of a sample cell. Due to its small size, the stirring bar fits into even 2 mm thick cuvettes. Since the rotation of the stirring bar is achieved with a magnetic field the stirrer can be used with hermetically sealed cells.
