Abstract: A body member is disclosed which has a shape compatible with a discrete sample container and at least one ramp surface for the purpose of propelling and thereby mixing a fluid in a container as the body is rotated. A filter is attached to one end of the body member for the purpose of intercepting unwanted particles and fibers in the fluid. A magnet is embedded in the body to render the mixing body and filter combination responsive to alternating magnetic fields thereby causing rotation.
