Introduction

Chaojun Zhou is a notable inventor based in Richmond Hill, Canada. He has made significant contributions to the field of biologic sample preparation, holding 2 patents that showcase his innovative approach to liquid handling systems.

Latest Patents

One of his latest patents is a biologic sample preparation system and related method. This system is designed to prepare samples for processing and includes a frame that defines a horizontal plane, a pipette assembly, a sample module, and an extraction module. The pipette assembly features a first pipette that is movably mounted to the frame, allowing for operation in a direction substantially perpendicular to the horizontal plane. The sample module, which includes a sample plate, is also movably mounted to the frame and can move substantially parallel to the horizontal plane. The extraction module, equipped with an extraction plate, is similarly designed for movement parallel to the horizontal plane, enhancing the efficiency of sample preparation.

Another significant patent by Zhou is the integrated pipetting apparatus. This pipette module includes a pipette-module frame that can be attached to the z-axis frame of a liquid handling system. A translatory-motion frame, which is movable by a motor, is attached to the pipette-module frame. The pneumatic aspirator assembly, which includes a cylinder, tube, tube tip, and pressure sensor, is also part of this innovative design. The controller for the pipette module features a liquid surface detection mode that enables a pressure feedback control algorithm, allowing for precise control during liquid handling.
