A completely self-contained replaceable cartridge for micro jet dispensing assemblies is thinner than the spacing between a standard âDIPâ socket. Each cartridge body contains a preferably embedded digitally operated micro jet piezoelectric ejector, a tubular capillary reservoir and fixed connecting pins spaced to removably plug into a standard dual in line packaging (DIP) socket strip or board to receive digital ejection signals. A plurality of the individual replaceable cartridges can be closely positioned together in âbanksâ which plug into standard DIP sockets. One or more âbanksâ can be plugged into sockets on a housing containing a chamber into which the micro-droplets are deposited. An air movement device may be included with the housing to disperse volatile material that has been ejected into the chamber. The chamber preferably contains a heatable surface onto which the volatile fluids are ejected from the orifices and whereby instantaneous volatilization of the fluid will take place.
