    摘要: Provided are a cell chip and a system thereof that are capable of detecting optimal conditions for stem cell differentiation by mechanical stimuli. The cell chip for cell differentiation experimentation includes a plurality of cell chambers for storing cells and culture media, cell and culture medium injection ports for transferring the cells and culture media to corresponding cell chambers, fine passages for moving the cells and the culture media injected into the cell and culture medium injection ports to the cell chambers, pneumatic injection ports for injecting pneumatic pressures applied to the cell chambers, and apertures having circular films for transferring the pneumatic pressures injected through the pneumatic injection ports to corresponding cell chambers. Here, at least two of the apertures may have different areas to vary the magnitude of pneumatic pressure applied to corresponding cell chambers.

    摘要: A device for dispensing liquids includes one or more liquid outlet means carried on a movable head. The device forms part of an automated excision apparatus for cutting biomolecule spots from an array of such spots carried in a gel. The head is mounted on an automated motion control system to allow for movement of the head in X, Y, Z directions under the control of a control means. A displacement means for causing the dispensing of liquid from the one or more liquid outlet means of the device is also carried by the moveable head carrying the liquid delivery outlets allowing the length of the tubing between the outlet and the aspiration device, typically a syringe, to be much shorter. This means that swelling and contraction of the tube is minimized during liquid handling operations which means more accurate delivery of specified volumes through the outlet. The syringes and the outlets are mounted on opposite sides of an axis of movement of the apparatus, keeping the machine compact. Typically the axis will be a horizontal X or vertical Y axis defined by a beam or the like which supports the movable head.

    摘要: A multi-channel fluid dispenser includes a reservoir with multiple internal chambers, a multi-channel liquid dispensing head, a plurality of fluid-delivery conduits, and support and positioning elements. The fluid-delivery conduits receive liquid from the chambers in the reservoir and deliver it to the dispensing head. The support and positioning elements are operable to support and position the dispensing head so that it can deliver the liquid from the reservoir to an underlying receiver. The fluid-delivery conduits include one or more optional flow control features that improve the accuracy of the dispensing operation. The multi-channel liquid dispensing head, which includes a valve-support member, a plurality of valves and a plurality of nozzles, is advantageously movable in three directions to facilitate alignment with an underlying receiver. Movement of the dispensing head along two axes is provided by the simple expedient of elongate holes having their long axes aligned in mutually orthogonal directions. In some embodiments, the valves are tiltable away from the vertical so that liquid dispensed from such tilted valves is directed at a non-normal angle into a receiver.
