Claim:
A patch-clamp cartridge comprising: an extracellular component including a plurality of separate extracellular chambers formed in an extracellular structure of unitary construction, each extracellular chamber being isolated from other extracellular chambers and sufficiently deep to surround a respective portion of extracellular fluid required for patch-clamp testing; an intracellular component including a plurality of separate intracellular chambers formed in an intracellular structure of unitary construction, each intracellular chamber being isolated from other intracellular chambers and corresponding to a respective extracellular chamber; an apertured partition sandwiched between the extracellular component and the intracellular component; a common extracellular electrode connecting said plurality of extracellular chambers in said extracellular component through a corresponding plurality of extracellular electrode elements exposed to said extracellular chambers through an interface between the partition and the extracellular component; and a plurality of individual intracellular electrodes, each of said intracellular electrodes being inserted in a respective intracellular chamber.
