Claim:
1. A sample processing device comprising: a receiving chamber having a chamber inlet and a chamber outlet; a cap having a protrusion that forms a piston relative to the receiving chamber when the cap is joined to the receiving chamber; a plate disposed within the receiving chamber between the cap and the chamber outlet; and a biasing member operable to urge the plate away from the chamber outlet, a metering reservoir fluidically coupled to the chamber outlet; and a vessel fluidically coupled to the metering reservoir by a syphon, the syphon being operable to actuate upon a preselected volume of liquid being received at the metering reservoir, wherein a base of the piston forms a first macerating surface, wherein a second surface of the plate forms a second macerating surface, and wherein rotation of the cap results in a grinding motion being applied to a sample positioned between the first macerating surface and the second macerating surface, wherein the syphon comprises a syphon inlet and a syphon outlet, the syphon outlet being fluidically coupled to the vessel, and wherein the preselected volume of liquid corresponds to a volume of liquid necessary to deliver a metered volume of fluid to the vessel.
