DIAGNOSTIC SYSTEM AND METHOD
A nucleic acid diagnostic system includes a unit-dose reagent compartment storing at least one unit-dose pack, one or more unit-dose pack loading stations for holding a unit-dose pack at a location that permits a substance transfer device to dispense a reconstitution reagent into each well of the pack, a unit-dose pack distributor configured to transfer a unit-dose pack from the unit-dose reagent compartment to one of the unit-dose pack loading stations, and an electrostatic generator disposed within the housing of the unit-dose reagent compartment and/or adjacent the one or more unit-dose pack loading stations. The electrostatic generator imparts an electrostatic charge to each of the wells of the unit-dose pack and/or to a lyophilized reagent pellet within each well so that the electrostatic charge positions and holds each lyophilized reagent pellet at a bottom of each respective well of the unit-dose pack.
PROCESSING VIAL AND CAP
A cap and a processing vial configured for interlocking engagement. The processing vial includes a locking collar surrounding an open upper end of the processing vial with lateral through holes formed through the locking collar. The vial also includes a latch hook located above each through hole. The cap includes a latch collar extending about a lower portion of the cap, where the latch collar is configured to snap in beneath the latch hooks of the processing vial when the lower portion of the cap is inserted into the open upper end of the processing vial to lock the cap to the processing vial.
Test Tube Capping And De-Capping Apparatus
An apparatus for automated capping and de-capping of test tubes having an ejector pin system for individualized cap ejection.
Method for conducting an assay
A method for performing a nucleic acid amplification assay employs a thermally-conductive receptacle holder with one or more receptacle wells, each conforming to an outer surface of a lower portion of a vial. A through-hole extends from an inner surface of each well to an outer surface of the holder. A thermal element is positioned proximal to the holder for altering a temperature of the holder. A signal detection module is configured to generate an excitation signal directed through the through-hole of the well and detect an optical emission from a fluid contained in the vial supported by the well. At least one well supports a capped vial containing a reagent for a nucleic acid amplification assay and including an opaque cap sealing an open end of the vial. The lower portion of the vial is contained within a well, and the cap is situated above a top surface of the holder.
Plate with wells for chemical or biological reactions, and method for multiple imaging of such a plate by means of an imaging system
The present disclosure provides a plate comprising an array of wells for chemical or biological reactions, wherein each of the wells comprises a reaction chamber with at least one opening on a surface of the plate. The array of wells consist of a plurality of adjacent blocks of wells, wherein each block of wells consists of a plurality of adjacent rows of wells, and wherein at least one void is provided in each block of wells in between the rows of wells. Here, the void is particularly part of the surface of the plate and lacks a well opening. Furthermore, a method for multiple imaging of such a plate by means of an imaging system is provided with the present disclosure.
Automated bacteria identification and antibiotic susceptibility profiling device
Systems and methods of testing a fluid sample are provided. A method can include controlling an orientation of a loader including a sample holder configured to hold a sample vessel to correspond to a first predetermined tilt angle. The method can include controlling an articulator to transfer the fluid sample from the sample vessel to at least one well of a plurality of wells of a multiwell plate positioned on a plate deck within the enclosure. The method can include controlling the articulator to move the multiwell plate to a hotel incubator within the enclosure. The method can include applying a bacteriophage to the fluid sample. The method can include controlling the articulator to move the multiwell plate from the hotel incubator to a testing system within the enclosure after a predetermined reaction time period. The method can include receiving output data from the testing system.
Systems and methods for automated sample handling
Embodiments of systems and methods for automated sample handling are disclosed. In an example, a system for automated sample handling includes reaction wells, a magnet, a magnetic manipulator, and a punch. The reaction wells are configured to each hold a reagent and collectively move horizontally. A first reaction well holds magnetic beads, and a second reaction well is partitioned by a seal. The magnet is configured to move vertically and capture the magnetic beads on a bottom surface of the first reaction well when moving to an upper position beneath the first reaction well. The magnetic manipulator is configured to manipulate the magnetic beads and includes a magnetic rod configured to move vertically to be above or in the first reaction well and a sheath below the magnetic rod and configured to move vertically and receive the magnetic rod. The punch is configured to move vertically and break the seal of the second reaction well when moving to a lower position in the second reaction well.
BIOLOGICAL MATERIAL PURIFICATION DEVICE AND PROCEDURE USING MAGNETIC BEADS
An automated workstation configured for magnetic bead nucleotide purification may be provided with a bead mover device, a working nest and a plate hotel. In some embodiments, the bead mover device includes a housing, a magnetic head assembly having an array of downwardly extending elongated magnets and a leadscrew located within the housing and configured to move the magnetic head assembly along a vertical axis. The working nest may be located on the frontside of the bead mover housing below the magnetic head assembly, and the plate hotel may be located on the backside of the housing and configured to hold a plurality of fixtures when not in use on the working nest. Methods of use are also disclosed.
