There is disclosed a method for reading machine-readable labels disposed on receptacles carried on a receptacle rack and associating receptacle data read from each machine-readable label disposed on at least one of the receptacles with a rack-receiving location, said method comprising: (a) providing an apparatus comprising a plurality of rack-receiving locations, each configured to receive a rack holding at least one receptacle, and a label reading device configured to read a rack-identifying machine-readable label disposed on the rack and machine-readable labels disposed on the at least one receptacle held on the rack, wherein the label reading device is disposed adjacent to one of the rack-receiving locations; (b) placing a rack holding at least one receptacle having a machine readable label disposed thereon in the rack-receiving location of the apparatus; (c) during or after performing step (b), reading the machine-readable label of each receptacle having a machine-readable label to obtain receptacle data for each receptacle having a machine-readable label; (d) during or after performing step (b), reading the rack-identifying machine readable label to obtain rack identifying data; (e) storing the receptacle data obtained in step (c) and the rack identifying data obtained in step (d) and associating the receptacle data obtained in step (c) with the rack identifying data obtained in step (d); (f) removing the rack from the rack-receiving location disposed adjacent to the label-reading device; (g) placing the rack removed in step (f) in one of the other rack-receiving locations; (h) during or after performing step (g), reading the rack-identifying machine readable label to obtain rack identifying data; (i) acquiring location data identifying the rack-receiving location in which the rack was placed in step (g); and (j) retrieving the receptacle data stored in step (e) that is associated with the rack-identifying data obtained in step (h) and associating the retrieved receptacle data with the location data acquired in step (i) to thereby associate the retrieved receptacle data with the rack-receiving location in which the rack was placed in step (g).
摘要:
There is disclosed a method of measuring at least one time-varying signal emission from the contents of a receptacle while the contents are subject to repeated cycles of temperature variations within a thermal cycling range, the method comprising: measuring the signal emission from the contents of the receptacle at repeating intervals of time and recording the signal emission measurement and a time stamp at each interval; recording a time stamp for each temperature of the thermal cycling range; and synchronizing the signal emission to a specific temperature within the thermal cycling range by comparing time stamps of the signal emission measurements to a time stamp for each temperature of the thermal cycling range.
摘要:
There is described an apparatus for transferring one or more receptacles between a plurality of receptacle-receiving structures, one or more of the receptacle receiving structures including a receptacle transfer portal through which a receptacle is placed into or removed from the receptacle-receiving structure and a door disposed over the receptacle transfer portal, said apparatus comprising: a receptacle carriage adapted to carry a receptacle and to selectively stop at a transfer position with respect to any of the receptacle-receiving structures, and wherein said receptacle carriage includes a receptacle moving mechanism adapted to move a receptacle with respect to said receptacle carriage to move a receptacle into said receptacle carriage, move a receptacle out of said receptacle carriage, or alternately move a receptacle into and out of said receptacle carriage, wherein a portion of said receptacle carriage is adapted to engage a door of a receptacle-receiving structure and to open the door upon performance of a predetermined movement of said receptacle carriage with respect to the receptacle-receiving structure; and a carriage positioning system adapted to automatically position said receptacle carriage so that a portion of said receptacle carriage engages a door of a selected one of the receptacle-receiving structures and to effect the predetermined movement of said receptacle carriage to open the door.
