Abstract

A turntable mixer, for mixing a sample container, comprising a rotation mechanism, a cycle timer, and a speed controller. The rotation mechanism has a turntable disk for supporting the sample container, and a motor for rotating the turntable disk. The cycle timer has a time-on controller for adjusting a time-on interval, and a time-off controller for adjusting a time-off interval. The rotation mechanism is enabled during the time-on interval, and disabled during the time-off interval, the time-on interval and time-off interval are repeated indefinitely to create a mixing duty cycle. The rotation speed of the turntable disk is adjusted by the speed controller.
