Popis:	Experimental setup for the thermal conductivity measurement of amorphous solids with the glass transition temperature below 250 K is presented. This setup allows to heat the specimen to the melting point and then cool it fast to the glass transition temperature. Thermal conductivity can be investigated in the temperature range from 5 K to 300 K. Thermal conductivity of ethanol in amorphous and polycrystalline states was measured for the verification of the setup function. The results of the measurements agree well with those presented in literature.
