A kit, an apparatus, and method are provided for developing a latent print. The apparatus comprises a pellet comprising a substrate impregnated with a sublimation compound, a receptacle, an adapter, and an end cap. The receptacle is open at a first end and detachably connected to a heat source at a second end. The receptacle is designed to receive and accommodate the pellet through the first end of the receptacle. The adapter defines an annular space for transmission of heat from the heat source to the pellet. The first end of the adapter is connected to the second end of the receptacle and the second end of the adapter is in communication with the heat source. The end-cap comprising a mesh window in an annular space of the end-cap allows passage of the fumes released from the pellet through the open end of the end cap towards the latent print for development.
