    Abstract: 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.

    Abstract: A piezoelectric dispensing apparatus (10) includes a piezoelectric dispensing device (20) including a fluid reservoir (20a) and a piezoelectric dispensing tube (70). The apparatus includes a seat for receiving the device and a plunger which is shaped and configured to abut with and seal the top of the reservoir and which defines a through bore to permit the application of vacuum and or pressure to the reservoir through the bore. The plunger may be moved up and down towards and away from the seat. The fluid reservoir defines an open top and an outlet at the base of the reservoir closed by a filter. The base of the reservoir define a foot. A secondary filter assembly is attachable to the base of the reservoir. The secondary filter assembly defines a bore which is in fluid communication with the reservoir when the secondary filter assembly is attached thereto, The secondary filter assembly also defines means for removably attaching the piezoelectric dispensing tube in fluid communication with the bore. The device includes a ducks bum valve or septum for closing the outlet of the reservoir until the reservoir is attached to the removable secondary filter assembly.

    Abstract: Separation of macromolecules by one-dimensional or two-dimensional methods, such as gel electrophoresis, produces an array of macromolecules, which can be transferred to a support, thereby producing the same array as on the gel. In the case of one-dimensional gel electrophoresis, because of the regular spacing of the gel lanes and the predictable direction of migration of the macromolecules, the positions of the macromolecule spots or bands in the array can be predicted to be at least within the area of the support corresponding to the lanes of the gel. Where the molecular weight of a macromolecule of interest is known, molecular weight markers can be used to determine where the macromolecule band is on the support, even if the macromolecule is not stained in the gel or on the support. Assays that reveal characteristics of the macromolecule can be carried out by spotting reagents onto the support in a series of microspots of small volume in a line which intersects the macromolecule band, and which corresponds to the line of the direction of migration of the macromolecules on the gel. Appropriate detection methods can be applied, depending on the reagent, to see the results. The steps for locating the bands of macromolecules, applying reagents, and detecting the effect of the reagent on the macromolecule can be automated in an appropriate instrument.

    Abstract: A sampling device includes a table (12) and an overhead beam (14) which is spaced and supported above the table by two columns (16, 18). In the center of the beam, a cutting tool (20) assembly is located. The table is mounted so as to be moveable in the x and y directions in a generally horizontal plane. By moving the table in the x and y directions, any part of the table may be located under the cutting tool assembly. A computerized controller includes a digital scanner to record an image of an array of samples on the table and control the cutting tool to cause it to cut out a sample from the array, pick it up and transfer it to a selected location.
