1. A device for collecting and processing bone fragments, said device comprising:
a chamber member at least partially defining a volume,
a press member at least partially disposed within said volume;
a compression surface defined by one of said chamber or press member;
a filter support surface defined by the other of said chamber or press member and configured to support a filter;
an intake port configured to receive a composition comprising bone fragments; and
a vacuum port configured to be coupled to a vacuum source;
wherein said chamber member and said press member are rotationally coupled with one another; and
wherein the composition is acquired through said intake port and collected in said volume between said compression surface and said filter support surface, and application of rotational force to said chamber or press member in a first direction moves said compression surface and said filter support surface together to compress the composition between said compression surface and said filter support surface to compact and further remove filtrate from the composition.
