Abstract: An electrophoresis system includes a pedestal including a base, two enlargements at both ends of the base respectively, two cavities in the enlargements respectively, and a transparent plate on top of the base; a photographic filter member provided on the top of the base; a control panel on one enlargement; an electrophoresis tank provided between the enlargements; a covering member releasably provided on the pedestal for concealing the electrophoresis tank; a gel block in the electrophoresis tank for holding DNA samples in place; LED lamps in each cavity, the LED lamps being for emitting blue light toward the DNA samples; a hollow mount on the covering member and including a sliding tray; a photographic filter releasably disposed on the tray; and a picture taking device mounted on the hollow mount.

Abstract: A motor driven rotating device is disclosed that includes a fixed base, an eccentric rotating mechanism above the base, first magnets in the base, and second magnets in the rotating mechanism. A polarity of each first magnet is opposite to that of each second magnet so as to maintain a gap between the base and the rotating mechanism. Also, the rotating mechanism is adapted to eccentrically rotate.
