  • Patent number: 8758683
    Abstract: A system and method for processing, i.e., sampling and tracking, plant material requires the ability to identify each plant in a plurality of plants. Initially, samples are taken from selected plants and are collected in respective storage locations in a magazine. During sampling, the identity of the plant source for each plant sample is stored. Further, the identity of each storage location receiving a plant sample is stored. Subsequently, the samples are transferred from the storage locations and are placed in respective wells of a receiving member for further downstream processing. Again, the identity of each well receiving a plant sample is stored. As a result, a plant sample in a well can be traced back to its plant source.

  • Patent number: 8437874
    Abstract: Systems and methods for processing plant material samples and a transfer station designed for use in such systems and methods. In one embodiment, the system includes a controller, a plant-material sampling device, and a transfer station. The plant-material sampling device is configured to communicate with the controller and to read an identifier of a plant. The sampling device also has a removable magazine, and is designed to take at least one plant sample from multiple plants, place such samples in the magazine, and track the identity of the plant from which each sample is taken. The transfer station is configured to hold, at multiple positions, multiple magazines and multiple trays such that the positions of the magazines are mirrored by the positions of the trays, read an identifier of each magazine, read an identifier of each tray, map storage locations for each one of the magazines to storage locations of one of the trays, and sequentially unload plant samples from the magazines to the trays.

  • Patent number: 6918738
    Abstract: A holding plate includes a flat base member with a surface that is formed with a plurality of stations (wells or depressions) for holding specimens. A panel extends downwardly from the edge of the surface to create a concavity for receiving a lid member therein. The panel also has a flange extending outwardly from the concavity. The flat lid member has a skirt with a rim that extends from the edge of the lid member to create a hollow for receiving a base member therein. In operation, a robot or mechanical device selectively engages the flange of the base member and the rim of the lid member to engage or disengage the base and lid members. This allows for individual movement of either the base member or the lid member. This also allows for collective movement of the engaged base and lid members for stacking and storage.
