  • Publication number: 20120201721
    Abstract: A slide processing apparatus is disclosed. The apparatus comprise a liquid transporter for transporting a staining liquid reserved in a first liquid container and a washing liquid reserved in a second liquid container; a first instruction receiver for receiving a first instruction that instructs to initiate preparation of a slide stained with the staining liquid; a second instruction receiver for receiving a second instruction that instructs to initiate washing of a housing element which accommodates therein a slide to be stained; and a controller. When receiving the first instruction, the controller performs staining of the slide accommodated in the housing element by causing the liquid transporter to transport the staining liquid into the housing element. When receiving the second instruction, the controller performs washing of the housing element by causing the liquid transport to transport the washing liquid into the housing element.

  • Publication number: 20120064638
    Abstract: A sample processing apparatus for performing a process including a plurality of steps on a sample, the sample processing apparatus sequentially processing a plurality of samples, is disclosed. The apparatus comprises a plurality of units corresponding to the respective steps in the process; a transfer section which transfers a sample to the units according to a flow of the steps; and a controller. Specifically, when an operation was not performed successfully, the controller interrupts the process for a sample that had not reached the location where the unsuccessful operation was performed while continuing the process for a sample that had already passed the location, retries the operation that was not performed successfully, and resumes the interrupted process when the retried operation has been performed successfully.
