SYSTEM FOR READING MACHINE-READABLE LABELS ON SAMPLE RECEPTACLES
A system including a housing, a sample rack for holding a plurality of sample receptacles, and a reader for reading two-dimensional machine-readable labels associated with the plurality of sample receptacles as the sample rack moves between first and second positions within the housing. The system further includes a processing and control unit adapted to decode the two-dimensional machine-readable labels read by the reader and to associate each of the decoded two-dimensional machine-readable labels with an associated sample receptacle based on a measured position of the sample rack when the two-dimensional machine-readable label was read.
1 . A system for reading machine-readable labels on sample receptacles, comprising:
a housing;
a sample rack configured to hold a plurality of sample receptacles, each having a two-dimensional machine-readable label and configured to move between a first position and a second position within the housing;
a reader configured to read the two-dimensional machine-readable label of each sample receptacle of the plurality of sample receptacles as the sample rack moves between the first position and the second position; and
a processing and control unit configured to decode the read two-dimensional machine-readable label of each sample receptacle of the plurality of sample receptacles and configured to associate the decoded two-dimensional machine-readable label of each sample receptacle of the plurality of sample receptacles with the corresponding sample receptacle based on a measured position of the sample rack when the two-dimensional machine-readable label was read.
2 . The system of claim 1 , wherein the system is configured such that the sample rack is manually moved between the first position and the second position.
3 . The system of claim 1 , wherein the system is configured such that the sample rack is automatically moved between the first position and the second position.
4 . The system of claim 1 , wherein the reader is disposed within the housing or coupled to the housing.
5 . The system of claim 1 , wherein the processing and control unit is disposed within the housing or coupled to the housing.
6 . The system of claim 4 , wherein the processing and control unit is disposed within the housing or coupled to the housing.
