Abstract Isospin effects of the critical phenomena were studied via Xe isotopes in the frame of the lattice gas model. All the critical temperatures for four Xe isotopes are close to 5.5 MeV at the same freeze-out density of about 0.39 ρ0. The critical values of power law parameter of mass distribution, mean multiplicity of intermediate mass fragments, information entropy and Campi's second moment show minor dependence on the isospin at the critical point.
