A system for sampling a heated product comprising: a disposable first subassembly that comprises: a reservoir that is capable of holding a product, an elongated neck that is connected to the reservoir in a detachable manner, and a hollow applicator head that depends from the elongated neck into the reservoir; wherein a portion of the applicator head seals off the product in the reservoir from the ambient atmosphere; a reusable second subassembly that is physically separate from the first subassembly, that comprises: a handle, a power source located in the handle; an electric circuit housing that is opened at an upper end and a lower end, that is able to form a rigid, detachable connection to the elongated neck, the electric circuit housing being fitted to and extending beyond the handle; an electric heating circuit, that passes through the electric circuit housing, such that a heat generating portion of the heating circuit emerges from the lower end of the housing; wherein when the electric circuit housing is made to form a rigid connection to the elongated neck, then the heat generating portion is disposed inside the applicator head; wherein a top end (1 a) of the reservoir is connected to a bottom end of the elongated neck, such that an orifice (1 c) of the reservoir is surrounded by the elongated neck; characterized in that the reservoir and elongated neck articulate along a surface of joining that is relatively weak compared to the surrounding structure. a disposable first subassembly that comprises: a reservoir that is capable of holding a product, an elongated neck that is connected to the reservoir in a detachable manner, and a hollow applicator head that depends from the elongated neck into the reservoir; wherein a portion of the applicator head seals off the product in the reservoir from the ambient atmosphere; a reservoir that is capable of holding a product, an elongated neck that is connected to the reservoir in a detachable manner, and a hollow applicator head that depends from the elongated neck into the reservoir; wherein a portion of the applicator head seals off the product in the reservoir from the ambient atmosphere; a reusable second subassembly that is physically separate from the first subassembly, that comprises: a handle, a power source located in the handle; an electric circuit housing that is opened at an upper end and a lower end, that is able to form a rigid, detachable connection to the elongated neck, the electric circuit housing being fitted to and extending beyond the handle; an electric heating circuit, that passes through the electric circuit housing, such that a heat generating portion of the heating circuit emerges from the lower end of the housing; wherein when the electric circuit housing is made to form a rigid connection to the elongated neck, then the heat generating portion is disposed inside the applicator head; wherein a top end (1 a) of the reservoir is connected to a bottom end of the elongated neck, such that an orifice (1 c) of the reservoir is surrounded by the elongated neck; characterized in that the reservoir and elongated neck articulate along a surface of joining that is relatively weak compared to the surrounding structure. a handle, a power source located in the handle; an electric circuit housing that is opened at an upper end and a lower end, that is able to form a rigid, detachable connection to the elongated neck, the electric circuit housing being fitted to and extending beyond the handle; an electric heating circuit, that passes through the electric circuit housing, such that a heat generating portion of the heating circuit emerges from the lower end of the housing; wherein when the electric circuit housing is made to form a rigid connection to the elongated neck, then the heat generating portion is disposed inside the applicator head; wherein a top end (1 a) of the reservoir is connected to a bottom end of the elongated neck, such that an orifice (1 c) of the reservoir is surrounded by the elongated neck; characterized in that the reservoir and elongated neck articulate along a surface of joining that is relatively weak compared to the surrounding structure.
