An automated system and method for individually processing multiple specimens of particulate matter-containing liquid in respective containers. The containers are transported seriatim along a processing path to present them to, at least, a preprocessing apparatus (e.g., a mixing head), and then to a specimen acquisition apparatus, which removes preprocessed specimen fluid from the container for subsequent analytical testing or evaluation. Each apparatus is actuated in response to presentation of a container thereto so as to carry out its respective operation independently. An exemplary system can include, in sequential order, stations for container loading and unloading, container uncapping and cap disposal, specimen mixing, filter loading, specimen acquisition (e.g., by aspiration, and then slide printing), filter disposal, and container resealing. The system is capable of unattended operation for many hours at a time, and can interface with an integrated data management system to provide fully integrated specimen and information management in a complete diagnostic laboratory system.

An automated method according to claim 7 or claim 8, further comprising pressing seriatim each filter through which aspirated liquid has passed against a respective slide positioned in proximity to the processing path to transfer the particulate matter sample from the filter to the slide. 10. An automated method according to claim 7, wherein the filter magazine of the filter loading head is adapted to store at least two types of filters, and the filter type dispensed into the particulate matter separation chamber is governed by information specific to the specimen presented. 11. An automated method according to claim 7, claim 8 or claim 10, wherein the specimen acquisition head is adapted to mix the specimen in each container presented to it, the method including actuating the specimen acquisition head to mix the specimen immediately prior to the aspirating operation. 12. An automated method according to claim 11, wherein the specimen acquisition head mixes the specimen more slowly than the mixing head. 13. An automated method according to claim 12, further comprising pressing seriatim each filter through which aspirated liquid has passed against a respective slide positioned in proximity to the processing path to transfer the particulate matter sample from the filter to the slide. 14.
