The invention provides for a dispensing assembly (100, 100', 100", 200, 300, 500, 600, 700, 900) comprising a cartridge holder (102). The cartridge holder is operable for receiving a cartridge (108, 108', 108") operable for dispensing a fluid (206). The cartridge comprises a reservoir (114, 804, 908) operable for receiving the fluid. The reservoir comprises an outlet (115, 806). The reservoir has an adjustable volume for forcing the fluid through the outlet. The cartridge further comprises a nozzle (116, 912) for dispensing the fluid. The nozzle is connected to the outlet. The dispensing assembly further comprises an actuator (104) for actuating the adjustable volume. The dispensing assembly further comprises an impulse generator (106) for imparting an impulse to the nozzle. The impulse generator comprises an actor (118) for contacting the nozzle. The dispenser assembly further comprises a controller (202, 420) for controlling the actor and the impulse generator.

The invention provides for a cartridge (100, 202, 202', 202", 400, 600, 800) for dispensing a fluid (104). The cartridge comprises a reservoir chamber (102) operable for receiving the fluid and for receiving a ventilation gas (106). The reservoir chamber comprises an inlet (114) for receiving the ventilation gas and an outlet (116) for dispensing the fluid. At least a portion (106) of the reservoir chamber is operable for being filled with the ventilation gas when in an operating position. The inlet is located in the portion operable for being filled with the ventilation gas. The fluid comprises a reagent. The cartridge further comprises a baffle means (108, 406, 602, 802) for restricting gas diffusion through the inlet. The reservoir chamber is operable for receiving the ventilation gas via the baffle means.
