AUTOMATED SAMPLE PROCESSOR

摘要

Provided is a liquid handling device (100) comprising: a cylindrical actuator cavity (120) in a substrate (101), the actuator cavity (120) intersected by two or more actuator channels (122); one or more chambers (110) with an access channel (112) adapted to connect to a separate one of actuator channels (122); and an actuator (150) comprising a cylindrical body having a cylinder axis and having therein a liquid-handling compartment (160) arrayed along the cylinder axis, a first end and a second end, the liquid-handling compartment (160) being closed at the second end, a dispensing channel (151) located at the second end and traversing the cylindrical body, the dispensing channel (151) adapted to be separately aligned with the actuator channels, wherein the actuator (150) is adapted to receive in a seal-tight manner a plunger (170) that operates to confine an effective chamber defined by the plunger (170) and the second end by moving toward the second end or to expand the effective chamber by moving toward the first end. Preferably, one or more of the chambers are formed within the substrate (101).
