A simply designed cell for thermal conductivity measurements of low vapor-pressure liquids

Abstract

We have built a simply designed cell for the measurement of the thermal conductivity of liquids under steady state conditions from room temperature to about 60C. Thermal conductivities measured in the range between 0.2 and 0.7 Wm-1K-1 show deviations of a few percent from reference thermal-conductivity data. The cell is made of two concentric parallel plates separated by a 0.44 mm thick sample. It is easily assembled and loaded with the sample for a quick and routine use. © 2011 American Institute of Physics.
