Method and apparatus for isolating and detecting biological and other particles
An apparatus and method for isolating bacterial particles in a sample using a container with material in temporary fluid blocking position to lower orifice in the container, a separation medium having an electrical conductivity lower than and physical density greater than that of the sample above the material that supports a sample concentrate after passing through the separation medium when exposed to centrifugal force, a heating element for liquefying the material to permit flow into a chamber past an electrode array that attracts and holds subject particles. The system allows rapid detection and isolation of particles from samples from animal, human, environmental sites, a bio-industrial reactor or a food or beverage production facility requiring relatively small volumes, short incubation times resulting in structurally intact particles for further analysis. Testing may be completed in a single unit that requires decreased technician manipulation, fewer steps and a decrease in cross-contamination.
