Claim 7:
8. A sampling device for concentrating a liquid specimen sample, the sampling device comprising:
(a) a filtration assembly, which comprises:
(i) a tubular container, which is shaped so as to define an inner wall and a proximal container opening for receiving the liquid specimen sample;
(ii) a plunger, which (A) comprises a plunger head, and (B) is insertable into the tubular container via the proximal container opening, such that a lateral surface of the plunger head forms a fluid-tight movable seal with the inner wall; and
(iii) a filter; and

(b) a filter-collection receptacle, which is disengageably coupled to the filtration assembly,
wherein the filtration assembly is configured such that movement of the plunger head within the tubular container, when the liquid specimen sample is contained in the tubular container and the filter is disposed in the tubular container, pushes at least a portion of the liquid specimen sample through the filter,
wherein the sampling device is configured such that the filter is advanceable into the filter-collection receptacle while the filter-collection receptacle is disengageably coupled to the filtration assembly,
wherein the filter-collection receptacle is shaped so as to define a receptacle opening, and wherein the sampling device is configured such that the filter is advanceable into the filter-collection receptacle via the receptacle opening while the filter-collection receptacle is disengageably coupled to the filtration assembly,
wherein the sampling device further comprises a shaft, and
wherein the sampling device is configured such that that a distal portion of the shaft is axially movable through the receptacle opening so as to advance the filter into the filter-collection receptacle via the receptacle opening.
