Abstract
The invention provides a lid mechanism suitable for use with automated instrumentation. The lid mechanism has a compact design enabling it to function in very small spaces, and therefore on very compact instrumentation. One embodiment of the lid mechanism has a nut positioned around a jackscrew; a motor translationally attached to the nut for driving rotational motion of the nut around the jackscrew and vertical motion of the jackscrew; a main shaft positioned around the jackscrew with a bearing support positioned on the main shaft; a moving support comprising a bearing guide track and positioned on the main shaft so that the bearing support is positioned within the bearing guide track; and a lid plate positioned on the moving support so that vertical movement of the moving support causes vertical movement of the lid plate and rotational movement of the moving support causes rotational movement of the lid plate. Also provided is an automated laboratory instrument having a lid mechanism of the invention.
