Abstract: A low profile platform mixer has a variable number of platforms. The degree of pivot or tilt the platforms undergo can be changed as can the motor speed, depending on the particular laboratory solutions which are to be stirred or agitated. The mixer is made from stainless steel and is suitable for autoclaving to insure cleanliness and sanitation. A stainless steel base rigidly supports a pair of stanchions to which platforms are pivotally connected. The motor and motor controls are also mounted on the base and the motor extends above the height of the first or lowest platform for use in limited space environments.

Abstract: A mixing device and method is provided for stirring solutions by imparting a rotational, undulating motion thereto. The mixing device includes a motor having a speed control which is eccentrically joined to a holding platform. Flexible connectors are attached to the platform to limit its movement and to cause the platform to undulate during its circular motion.
