MULTIPLE CHANNEL PIPETTING DEVICE

摘要

This invention is a multiple channel pipetting device for aspirating and dispensing volumes of liquid using disposable or non-disposable tips (34). The device is comprised of a main body (28) made of a hard synthetic material with multiple channels and an associated ram plate (16) 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 (26) moved with a synchronous fibrous belt (24) moved with a motor (20). A moveable plate (32) mounted to the bottom of the device to remove disposable tips is activated by a set of automated ejector plate arms (30). The entire device can be mounted in a self-contained housing or attached to another device allowing it to be moved.
