Claim 26:
27. A method for concentrating a liquid specimen sample, the method comprising:
placing the liquid specimen sample in a tubular container of a filtration assembly of a sampling device via a proximal container opening of the tubular container;
inserting a plunger head of a plunger of the filtration assembly into the tubular container via the proximal container opening of the tubular container, while a filter-collection receptacle is disengageably coupled to the filtration assembly, such that a lateral surface of the plunger head forms a fluid-tight movable seal with an inner wall of the tubular container;
distally advancing the plunger head within the tubular container to drive at least a portion of the liquid specimen sample through a filter of the filtration assembly;
advancing the filter into the filter-collection receptacle while the filter-collection receptacle is disengageably coupled to the filtration assembly; and
thereafter, decoupling the filter-collection receptacle from the filtration assembly by removing the filter-collection receptacle from the filtration assembly via the plunger-space proximal opening while the plunger head is within the tubular container,
wherein the sampling device further includes a shaft, and
wherein advancing the filter into the filter-collection receptacle comprises axially moving a distal portion of the shaft through a receptacle opening of the filter-collection receptacle so as to advance the filter into the filter-collection receptacle via the receptacle opening.
