Abstract:
1. A method for removing a biological sample pellet from surrounding media of a biological sample while reducing the risk of recontamination of the pellet with surrounding media, comprising: decanting the biological sample through a receiving cylinder into a tube, the receiving cylinder facilitating the slow release of the biological sample into the tube; passing the biological sample through a multi-layered gradient in the tube, the multi-layered gradient for removing at least one pathogen from the biological sample; and aspirating through an aspiration device a biological sample pellet formed from passing the biological sample through the multi-layered gradient, wherein the aspiration device is inserted into the sample pellet through an aspiration channel integrally related to the receiving cylinder to provide a non-contaminated environment from which to remove the biological sample pellet.
