An apparatus for dispensing a multiple-component substance from a multiple-barrel cartridge (e.g., a two-barrel adhesive cartridge) includes a housing having a slot for receiving a flange of the cartridge. Preferably, the housing includes a pivoting latch that rigidly secures the flange within the slot. Plungers positioned within the housing are received by the barrels of the cartridge. A motor, which is disposed in the housing and controlled by a microprocessor, is mechanically connected to the plungers and drives the plungers within the barrels. The motor may be connected to the plungers through a lead screw assembly, for example. Preferably, the housing is handheld for ease of operation and remote from a control unit containing the microprocessor. The control unit may include a keypad and screen, operatively connected to the microprocessor, for data entry and display. The dispensing apparatus permits precise placement of two-component adhesives, for example.
