Flow chambers are provided. In some embodiments, the flow chambers include an inner panel having at least one flow channel having an inlet/outlet opening on each end thereof formed therein, wherein the inlet/outlet openings are adapted to releasably receive a septum; one or more ports adapted to releasably receive a plug and for at least liquid communication with the at least one flow channel, and an outer frame that defines an outer portion of the at least one flow channel and that defines a perimeter of the flow chamber. In some embodiments, the flow chamber has overall dimensions of a standard multiwell plate and the at least one flow channel is located in a position that corresponds to a column location of the standard multiwell plate. Also provided are methods for producing the presently disclosed flow chambers and employing the same to assay biological features of cultured cells and/or tissues.
