Abstract:

An undulating mixing device for precise, controlled agitation of sensitive biological and chemical solutions provides a base and a platform connected by four flexible connectors, a spring loaded motor mount assembly pivotally attaching a motor to the base, a turntable rotatably attached to the base, a tilt assembly pivotally and rotationally attached to the turntable and rigidly affixed to the platform, and a motor shaft that engages a groove on the turntable for causing rotation thereof. The tilt assembly includes an adjustable collar which controls the tilt or yaw movement of the platform as the motor effects rotation of the turntable. A selectively adjustable speed control switch sets the desired rotational speed of the motor via a microprocessor. The device functions without modification on a plurality of selected voltages and frequencies for achieving the desired rotational speed.
