Method and apparatus for sonication in connection with preparing a cellular sample containing DNA or RNA for performance of polymerase chain reaction (PCR) or for other reasons where it is important to break down the cell walls and other cellular structures to release cellular contents including DNA. The same methods and apparatus may be used to release DNA or RNA from virus for PCR or other uses. A novel apparatus which is capable of releasing cellular contents or releasing the DNA or RNA of virus without the aid of beads or chemicals is described herein. The apparatus is designed to deliver high levels of sonic energy through optimizing the geometry the apparatus and optimizing the force created by a piezoelectric transducer. The apparatus is capable of processing samples which are contained within fluid in a short amount of time between 30 seconds and two and one half minutes. The apparatus is small and can be field deployable or used in a standard molecular biology laboratory.

Ultra sonic release of DNA or RNA

A movable filter system is provided for moving one or more filters of a filter assembly between an operative position and a maintenance position. In one embodiment, a filter assembly is secured to a telescoping rod assembly so that it may be moved between operative and maintenance positions. Positioning the rod assembly vertically allows gravity to move the rod assembly to an extended position, and a winch and cable may be used to move the rod assembly to a retracted position. Keyways and channels may be used within the rods of the telescoping rod assembly so as to maintain rotational positioning of the filter assembly.

A particle refining apparatus to be integrated into a system including a containment device and an influent conduit. The influent conduit is configured to retain the particle refining apparatus and connected to the containment device. The particle refining apparatus including a shaft, a blade set attached near the end of the shaft and attachment couplings arranged within the influent conduit. A method for refining particles includes introducing particles into an influent conduit, chopping the particles to a desired size with an initial chopping apparatus, directing the chopped particles through the influent conduit, refining the particles to a desired size with a refining apparatus, and moving the particles continuously from the influent conduit through the refining apparatus and into a containment device.
