Abstract
A motorized latch assembly includes an electric motor, an eccentric cam attached via gears to a shaft of the motor and a latch plate configured to lock the reagent cartridge to the coupler. The eccentric cam is rotated when the shaft of the motor rotates. When the eccentric cam is rotated so that the eccentric cam presses down upon the latch plate, the latch plate moves a sufficient distance to permit the reagent cartridge to be disconnected from the coupler.
