title: A temperature controller for in vitro recording chambers.
abstract: An inexpensive, electrically quiet temperature controller designed to provide biological temperatures in chambers used to maintain tissue slices for in vitro recording is described. The circuit incorporates several advantageous features: (1) an integrated circuit temperature sensor is used which produces a linear output and is immune to self-heating error; (2) a single +12-18 V, 1 A DC supply will power the unit; (3) the output regulator cannot be damaged by overheating or short-circuiting; and (4) the temperature of the preparation is displayed.
