Abstract
This invention is a multiple channel pipetting device for aspirating and dispensing volumes of liquid using disposable or non-disposable tips. The device is comprised of a main body made of a hard synthetic material with multiple channels and an associated ram plate activated by a four-quadrant synchronous drive. The drive assembly is mounted on four standoffs, and the ram plate moves up and down by the means of four lead screws moved with a synchronous fibrous belt moved with a motor. A moveable plate mounted to the bottom of the device to remove disposable tips is activated by a set of automated ejector plate arms. The entire device can be mounted in a self-contained housing or attached to another device allowing it to be moved.
