ABSTRACT:
There is provided a method and system for transferring biological material samples from the point of collection to a chamber for placement into a centrifuge for processing and analysis. A container is used to hold the sample from the point of collection and during transport to a sample chamber which is placed into the centrifuge. The container is provided with a threaded open end, the threads being complementary with screw threads on a lid and also with threads around a port in the chamber. Thus, the user collects the sample, places it within the container, and engages the lid to close the open end of the container. The container is transported to the laboratory, where the lid is removed, and the threads on the container engaged with the threads on the chamber to attach the container to the chamber. The container is then inverted to permit the sample to pass from the container into the chamber. The chamber may then be placed into a known centrifuge for processing. The system and apparatus are suited for the use of a curette as the tool for collecting the sample, and permit the sample-bearing curette to be conveyed in the container without contamination from the point of collection to the laboratory centrifuge. A system of notches and keys are provided to align a filter card and slide at the discharge end of the chamber and promote uniform filtering action.
