The phase diagram of agarose solution is studied as a function of the concentration of agarose and the temperature. The gelation temperature and the cloud point of the system are determined by the tilting method and the transmission of the laser light, respectively. It is found that the cloud point appears below the gelation temperature. The system is then studied by the light scattering technique using a home made apparatus. The results are discussed in terms of Cahn-Hilliard theory of the spinodal decomposition. The results obtained here indicate that the phase separation occurs in the gel state of agarose.
