  • Patent number: 7604999
    Abstract: A system and method for identifying a biological sample associated with a container is disclosed. A universally unique identifier is associated with each container. In one or more embodiments, the identifier comprises one or more markings having a specular reflectance which differs from the specular reflectance of the outer surface of the container adjacent the markings. A detection apparatus detects the differences in specular reflectance light to identify the identifier associated with the container. The identifier is associated with certain information regarding the container and biological sample. From that point forward, any information about the contents of the container may be retrieved by searching on its container ID. Because the container ID is assured by its manufacturer to be universally unique, the container and sample may move from one organization to another under the same identifier, and information about the contents of the container may be shared by querying on its container ID.

  • Patent number: 6890759
    Abstract: A system and method for identifying a biological sample associated with a container is disclosed. A universally unique-identifier is associated with each container. In one or more embodiments, the identifier comprises one or more markings having a specular reflectance which differs from the specular reflectance of the outer surface of the container adjacent the markings. A detection apparatus detects the differences in specularly reflected light to identify the identifier associated with the container. The identifier is associated with certain information regarding the container and biological sample. From that point forward, any information about the contents of the container may be retrieved by searching on its container ID. Because the container ID is assured by its manufacturer to be universally-unique, the container and sample may move from one organization to another under the same identifier, and information about the contents of the container may be shared by querying on its container ID.

  • Publication number: 20050042760
    Abstract: A system and method for use with a flow cytometer to improve event reading and data processing capabilities of the flow cytometer, while also providing efficient system configuration assessment capabilities. The system and method enables the flow cytometer to capture and sample an entire waveform representative of an event being read, and provides improved processing and analysis of the sampled data in a real time or near real-time basis. The system and method further enable the flow cytometer to assess its configuration and provide assessment results to an operator in an efficient and effective manner.
