Abstract: An automatic shell reloader is provided. The shell reloader includes an electric motor coupled to a wheel which, in turn, is pivotally secured at its perimeter to the actuator of the shell reloader. The wheel leverages the power of the electric motor and provides precise control of the reloading operation. The shell reloader is also provided with a current sensing switch to attenuate the electric motor in response to detection of a malfunction.

Abstract: A shell reloading tool is provided with a current sensor designed to automatically detect conditions indicative of a crushed shell and reverse and stop the motor to allow the hull to be removed and fixed prior to any additional damage being caused to the hull or reloader. A circuit board is provided to override the current sensor at the initial startup of the motor and at the highest pressure point of the reloading process.

Abstract: Methods and devices for performing multiple simultaneous reactions on a reaction surface are disclosed. Methods and devices for simultaneously interrogating multiple patient samples with multiple diagnostic reagents are disclosed.

Abstract: A flat plate dialysis and ultrafiltration cell and system are provided, having a sample chamber, syringe docking port, with a seal capable of providing a fluid-tight seal after being pierced by a needle, a needle stop capable of preventing a needle from entering the sample chamber, and a needle guide formed in a funnel shape in the syringe docking port to guide a needle toward the sample chamber. The sample chamber is also provided with a dialysis or ultrafiltration membrane provided along a portion of the chamber. The sample chamber is fluidly coupled to a distal end of the syringe docking port and a vent hole.

Abstract: A system and method for identifying the presence of specific nucleotide sequences in a target DNA sample is provided. The nucleotide detection system comprises a flat plate detection cell having a sample chamber, a membrane and an optical window providing optical access to the interior of the cell. A target DNA sample is mixed with labeled nucleotides and other chemistries, and undergoes a chemical reaction, such that if the DNA sample has the nucleotide, the resulting mixture will contain labeled nucleotides that have undergone a change in molecular weight. The reacted sample is applied to the sample chamber and the membrane in the flat plate nucleotide detection system is utilized to effect the separation of the smaller molecular weight labels from the sample.
