    Abstract: High throughput compound profiling systems, and related devices and sub-systems that can be used to perform various compound profiling processes are provided. These systems typically include work perimeters that are organized for optimum efficiency and processing accuracy. Further, these systems are readily adaptable for performing a wide array of assays, as many different system components are easily incorporated or interchangeable in a particular system. System components that are provided by the invention include cell culture dissociators, which can be used, e.g., to effect cell wetting, dissociation, and/or agitation applications. In some embodiments, these cell culture dissociators are included as components of automated cell culture passaging stations. Dispensing devices that permit on-the-fly fluid temperature regulation are also provided. In addition, various compound profiling methods, cell dissociation methods, uniform cell concentration dispensing methods, among other processes, are also provided.

  • Publication number: 20040157322
    Abstract: A fermentation apparatus is constructed to produce a known and repeatable amount of untainted fermentation product using multiple fermentation vessels. To facilitate further processing compatible with other product processing steps, the fermentation apparatus has an array of sample vessels arranged in a container frame. The container frame is configured to hold the sample vessels during fermentation and to transport the vessel array to or from another processing station. Corresponding to the number of sample vessels in the sample vessel array, a cannula array is configured such that each cannula may be placed inside a sample vessel. The cannula array is attached to a gas distributor that delivers oxygen and/or one or more other gases from a gas source through the cannula into the sample vessel. Because the fermentation volume for each individual sample vessel is smaller than a bulk fermentation apparatus, the fermentation product yields are predictable and cell growth rates can be effectively optimized.

  • Patent number: 6659142
    Abstract: A system and method for preparing and dispensing fluid mixtures is provided. Fluid wells are positioned below a plurality of fluid dispensing devices, such as syringes configured to dispense fluid into the individual fluid wells. The fluid dispensing devices are configured to be positionable relative the fluid wells to enable different fluid dispensers to be sequentially positionable over a particular fluid well. A controller controls the relative movement between fluid wells and the fluid dispensing devices. In a preferred embodiment, the controller selectively moves multi-well vessels in one direction and moves the fluid dispensing devices in a second direction so that when directed by the controller, a selected fluid dispensing device is enabled to deposit a determined quantity of a fluid into a selected individual well of the multi-well vessels.

  • Publication number: 20030108450
    Abstract: The specimen plate lid is generally a block, with a cover portion and a side portion. An alignment protrusion extends from the side portion and cooperates with an alignment member of the specimen plate to assist in manually or roboticly guiding the lid onto the specimen plate. An underside surface of the cover has a sealing perimeter for receiving a seal constructed from a compliant material, and shaped to cooperate with a complimentary sealing surface on the specimen plate. The lid is weighted so that when the lid is aligned and positioned on the specimen plate, the weight of the lid provides a gravitational force to sufficiently compress the seal against the sealing surface on the specimen plate. Accordingly, the lid is sufficiently sealed to the specimen plate to avoid contamination and impermissible drying.
