Abstract
A method and apparatus for electrical testing of membrane tissue employs a pair of rack sections which have cavities for receiving opposing end portions of the culture cup. The culture cup and rack sections are clamped together to form test chambers at opposing sides of the cup substrate on which the experimental tissue is grown. Electrode cartridges are inserted into axial bores of the receiving cavities to provide a test current through the membrane tissue. Integral connectors connect with conduits for passing irrigation streams through the test chambers.
