ABSTRACT OF THE DISCLOSURE A heating unit which may be used as a soft contact lens disinfecting unit and which embodies a case construction entirely of thermoplastic, or other low heat-conductive material. A heat conductive liquid such as molten wax, or oil, or both, is contained in the case and is used as a uniform heat transfer medium between electrical heating elements in the case and the surface of an in- cubator supported in the case which, likewise, is formed of low heat-conductive material. The heating unit in the embodiment to be described, is specifically constructed to produce or aid in dis- infecting so-called soft contact lenses intended for wearing in contact with the eye. The unit is more generally applicable, and may be used to advantage, when a low cost heating unit is desired which will raise the temperature of an object or a material to a given temperature, maintain it at or above the given temperature for a given time period, and then allow it to cool down and return to an ambient temperature condition.
