A biologic sample preparation system that prepares samples for processing includes a frame defining a horizontal plane, a pipette assembly, a sample module and an extraction module. The pipette assembly includes a first pipette. The pipette assembly is movably mounted to the frame in a direction substantially perpendicular to the horizontal plane during operation. The sample module includes a sample plate and is movably mounted to the frame. The sample module is movable substantially parallel to the horizontal plane at least from a sample area spaced from the pipette assembly and a working area proximate the pipette assembly. The extraction module includes an extraction plate and is movably mounted to the frame. The extraction module is movable substantially parallel to the horizontal plane at least from an extraction staging area spaced from the pipette, assembly and the working area proximate the pipette assembly.

Biologic sample preparation system and related method

A pipette modulehas a pipette-module frameattachable to the z-axis frameof a liquid handling system. A translatory-motion frameattached to the pipette-module frameis movable with respect thereto by a motor. A pneumatic aspirator assemblyincluding a cylinder, tube, tube tipand pressure sensoris attached to the translatory-motion frame. A pistondisposed in the cylinderis fixedly attached to the frame. A controllerfor the pipette modulehas a liquid surface detection mode which enables a pressure feedback control algorithm causing the motorto move the translatory-motion framein a z-axis translator motion until a change in a pressure in the tipas sensed by the pressure sensorindicates that the tiphas made contact with the liquid surface
