Patent ID: 7927867

Claim:
A device for evaluating the process of a multi-phased biological event the device comprising: (a) at least one housing, wherein each housing is capable of characterization, analysis and manipulation independent of any other housing and wherein the housing further comprises: (i) a chamber; (ii) an inlet connected to the chamber for delivering a substance into the chamber; (iii) an outlet connected to the chamber for removing the substance from the chamber; (iv) at least one porous membrane, wherein the membrane is situated within the chamber of the housing such that at least two compartments are created by the relation of membrane surfaces with the chamber wherein the housing disassembles into a top segment, thereby forming an upper compartment defined as being the top segment and the membrane, and into a bottom segment, thereby forming a lower compartment defined as being the remainder of the housing and the substance flows in a manner parallel to the membrane only in the upper compartment above the membrane such that flow perpendicular to the membrane is avoided; (b) a delivery means; and (c) a receiving means, wherein a substance is delivered into the chamber of the housing via the inlet and constituents of the substance engage in various phases of a multi-phase biologic process.
