  • Patent number: 11583861
    Abstract: In an example implementation, a reagent storage system for a microfluidic device includes a microfluidic chamber formed in a microfluidic device. A blister pack to store a reagent includes an electrically conductive membrane barrier adjacent to the chamber.

  • Patent number: 11181541
    Abstract: An automated pre-analytical processing method and an apparatus for pre-analytical processing of samples to be forwarded to an adjacent analyzer for analysis. Rack label information is read and communicated to a processor. From the rack label information, the processor determines where to route the rack. The pre-analytical system has a rack robot that conveys racks to discrete locations depending upon the routing information assigned to the rack by the processor. The pre-analytical system has an automated station that reads the labels of individual sample containers in the rack that are brought to the automated station on instructions from the processor. Depending on the type of sample container and the type of sample disposed therein, the samples are either prepared for analysis by the automated station or the sample containers are directly passed through the automated station. Prepared samples and passed through samples are passed individually to a batching rack.
