A sample tube includes a barcode split into components at the bottom of the sample tube. Each barcode component stores less than the full data output from the barcode, but the components combine to full data output. Redundant diagonal components provide for error checking. A center region between the barcode components supports an electrical circuit or an optical or acoustic window. The sample tube may have a sidewall with a substantially cylindrical open end and non-cylindrical end closed with a bottom, the non-cylindrical end orienting the sample tube in a rack. Additional non-cylindrical surfaces are provided to orient the sample tube relative to complementary surfaces at a gripper. The sample tube of a particular application is positioned in an acoustic dispensing system where acoustic waves are transmitted through a center window for surveying and dispensing.

A container is provided in the present disclosure. The container includes at least one outer wall that is made of a low temperature tolerant material where the at least one outer wall is arranged to substantially form the container with an opening end; a tube that is situated inside the at least one outer wall, where the tube and the at least one outer wall are substantially thermally insulated, and the tube is open at one end that is on a same side of the opening end of the container; and a container cover being shaped substantially to match the at least one outer wall, where the container over is capable of covering the opening end of the container.

Methods and systems for ordering assays which detect SNPs or gene expression are provided. The methods use PCR and RT-PCR procedures. Collections of stock assays are assembled using pre- and post-manufacturing quality control procedures and made available to consumers via the Internet. In addition, custom assays are prepared upon order from the consumer and these assays are also prepared using pre- and post-manufacturing quality control procedures. The assays are then delivered to the consumer.

A method to handle tubes in a diagnostic laboratory automation system comprising a control device and a tube-analyzing device is presented. The tube-analyzing device comprises a tube identification reader, a tube type recognition unit, a sample color determination unit, and a tube consistence unit. The tube identification reader reads tube identification device. The tube type recognition unit identifies tube type. The sample color determination unit determines sample color. The tube consistence unit determines sample consistency. The sample tube type, the tube type, the sample color, the sample consistency are send to the control device. The control device determines a construed tube type from one or more of the information of the tube type, the sample color, and the sample consistency. The control device checks whether the tube type matches the construed tube type and changes a used tube type from the tube type to the construed tube type.

A sample receptacle can be used for ordering assays to be performed by an automatic sample processing instrument. The sample receptacle can include a body defining a chamber for containing a sample and a label. The label can include discrete areas configured to be altered from a first assay order state to a second assay order state. Each discrete area has a known association with a different assay. The label can also include assay-identifying indicia indicating the respective assay associated with a respective discrete area. A method of processing a sample in a receptacle having one or more assay order states can include automatically determining assay order states of the discrete areas and performing an assay on the sample, using the automatic sample processing instruments, based on the determined assay order states of the discrete areas.

An analytic plate or other substrate having a permanent etchable, laserable, and/or developable marking surface coating (referred to herein as an etchable coating or as a developable coating) that is present on at least a portion of any side or surface thereof and is used to deposit a permanent indicium thereon, and a method of using the analytic plate or substrate.

The system for management of rack and tube positions for clinical chemistry laboratories includes tubes (10) capable of containing human biological material, a rack (20) configured for receiving and/or holding the tubes (10) to be stocked, a supporting base (30) configured for supporting the rack (20) thereon, a reader (50) configured for reading an identifier (R.sub.ID) of the rack (20) to be put onto the supporting base (30) and an identifier (T.sub.ID) of the tube to be put into the rack (20), a camera (40) for detecting the rack (20) on the supporting base (30), and at least one of the tubes (10) into the rack (20), a processing unit (60) for mapping the detected rack (20) into a plurality of allowed positions (Pi) and the detected tube (10) into a tube position (P) included in the plurality of allowed positions (Pi).

A container unit for handling containers includes a support surface arranged with a plurality of seats. Each of said sets is adapted to contain a container, and each container is provided with a container data carrier adapted to contain a unique identifier of the container. The container unit comprises at least one container unit data carrier adapted to contain data of the containers contained in the seats, said data comprising the unique identifiers of each container, and the position of each container in the seats. A nest locator is provided on the surface of the container unit. The nest locator is adapted to be the reference for mapping the position of the containers in the seats.

An automated system for performing nucleic acid amplification assays on samples provided to the system, where the system includes data input components configured to enable input specifying one or more user-defined assay parameters; data storage media storing a first set of assay parameters, the first set of assay parameters consisting of system-defined parameters, and a second set of assay parameters, the second set of assay parameters including the one or more user-defined parameters; and command input components configured to enable input specifying (i) that a first nucleic acid amplification assay be performed on a first sample in accordance with the first set of assay parameters, and (ii) that a second nucleic acid amplification assay be performed on a second sample in accordance with the second set of assay parameters. The system further includes one or more wash stations, a fluid transfer device, a thermal processing station, and a detection station for detecting the presence or absence of multiple analytes.
