An apparatus for dispensing material through a refillable cartridge, comprising a container having a receptacle for receiving a refill cartridge, the container having a lid cooperating with the container to enclose the refill cartridge, the container further comprising an exit port and a channel for communicating material from the refill cartridge to the exit port, and a valve for controlling the flow of material out of the refill cartridge; and a reusable, refill cartridge sized to be received in the receptacle, the refill cartridge including compressed gas and material separated by a bi-conical thruster, the refill cartridge further comprising a first end having a material inlet and outlet manifold, and a second end having a compressed gas inlet. The system's performance can be improved by applying a surface treatment to the wetted surfaces of the system to change the physical properties at the fluid/vessel interface.
