Patent ID: 7776273

Claim:
An extraction unit comprising: a carrier having an upper portion, a lower portion, and a bottom surface; and an extraction device for mating with the carrier having a first end, a second end, an inner surface, and an outer surface, comprising: a shoulder that extends outwardly from the outer surface and disposed between the first and second ends; a carrier-receiving portion at the first end comprising at least one flange that projects from the shoulder, comprises an inner surface, and is configured to secure the carrier to the extraction device in a compression-fit engagement; and a conduit interconnected to the carrier-receiving portion; the conduit extending between a first opening at the carrier-receiving portion and a second opening at the second end; wherein the carrier mates with the carrier-receiving portion, closes the first opening, seals the first opening to prevent fluid flow through the bottom surface, and forms a reservoir; wherein the inner surface of the at least one flange contacts the lower portion of the carrier; wherein the second end is adapted to mate with a vessel such that the vessel is in fluid communication with the conduit; and wherein specifically transferred material transferred to the carrier by microdissection and non-specifically transferred material are present on the carrier and some non-specifically transferred material is excluded from the reservoir and some specifically transferred material transferred is included in the reservoir.
