  • Patent number: 8327724
    Abstract: Apparatus for preparing a biological sample for PCR analysis has an inlet (4) for receiving the sample (15) and a sieve (13) through which the sample is forced by screwing down an inlet cap (16). A lysis solution between two rupturable seals (11 and 12) is effective to disrupt the cells of the sample and release nucleic acid. The apparatus is mounted releasably on a PCR machine (2) having a motor (2?) releasably coupled with a drive mechanism (3, 36,40) in the apparatus to effect a rotary and a vertical up and down movement of its components (30, 31, 32, 42). The apparatus has a transparent cuvette (5) and a needle (71) extending to the lower end of the cuvette, by which the prepared sample is dispensed to the cuvette for PCR analysis.

  • Patent number: 8138909
    Abstract: A method and apparatus for providing assay information to a portable detection unit, by way of a remote server in communication with the portable detection unit or a consumable with stored information for use with the portable detection unit. Global Positioning System (GPS) information is provided to a portable detection unit having a GPS receiver, so that the unit can determine its current position, including altitude. Based on the determined position, assays and parameters, such as PCR melt temperatures, can be selected. Assays to be performed by the portable detection unit can be selected based on the results of a prior assay.

  • Patent number: 8110397
    Abstract: A reconfigurable sample preparation device includes a rotary plunger device having a hollow body and a coupling device, provided above one end of the rotary plunger, and accommodating a sample. The device also includes at least one sealed reagent module. When the rotary plunger is rotated on the coupling device, a film of the reagent module is pierced, mixing the sample with a substance from the reagent module.

  • Publication number: 20110255083
    Abstract: A sealed and decontaminated fiber optic detection apparatus includes an optics portion with individual chambers. Each chamber housing optical and electro-optical components. A manifold accommodates fibers, with each of the fibers being in optical communication with the optical and electro-optical components of a corresponding chamber. The apparatus also includes a sample holder that holds a sample to be tested and a mounting device provided between the sample holder and the manifold. The mounting device and the manifold form a sealed fiber optic interface between the sample holder and the optics portion.

  • Patent number: 7682824
    Abstract: A holder for PCR sample collection and preparation and method of using which has a buffer container housing removably connected to a plunger housing. A swab attached to an end of a plunger collects a sample of a specimen to be analyzed for biological warfare agents. The swab and plunger are inserted into the plunger housing, a buffer container is positioned inside the buffer container housing and the buffer container housing and plunger housing are attached. A buffer passes through the swab and elutes off the sample and the sample mixes with a reagent. The prepared sample loads into a reaction tube, by a whipping action, for analysis.
