ABSTRACT:
A method of mixing fluid samples using an electromagnetic multidirectional shaker is provided. The shaker has a first electromagnet driving a first support panel in a first direction, and a second electromagnet driving a second support panel in a second direction. The first electromagnet is affixed to a base and is operatively attached to the first support panel which is suspended from the base via one or more first spring members. The first spring members are configured to bias the first support panel to an at-rest position after it has been displaced by the first electromagnet. The second support panel is in turn supported above the first support panel by one or more second spring members. The second electromagnet is affixed to the first support panel, and is operatively attached to the second support panel. The second spring members are configured to bias the second support panel to an at-rest position after it has been displaced by the second electromagnet.
