Abstract
An installation designed for measuring the thermal conductivity of organic materials, including biological tissues, is described at temperatures below room temperature up to 100 K using the method of stationary heat flow. The advantages of the installation include the ability to set the temperature regime of freezing the sample, smoothly changing the rate of temperature front movement in the sample during cooling. The output of the device to the preset stationary mode and the measurements are carried out automatically. The values of the coefficient of thermal conductivity of the muscle tissue calculated on the basis of the measurement results when the samples are cooled in the temperature range from 280 K to 100 K are in good agreement with the literature data.
