Differential microcalorimeter for liquid samples

Abstract
A microcalorimeter for liquid samples with high performance and low cost is described. It is essentially a differential apparatus in a ‘‘twin’’ configuration with two cylindrical cells. Two resistive sensors, put in a Wheatstone bridge, are wound on the cells to measure the temperature difference between them. Sensitivity, response time, and calibration procedure are reported. As illustrative example, the specific heat of some liquids at two temperatures has been measured.
