A cartridge for dispensing a fluid is provided, the cartridge comprising: a reservoir chamber configured for receiving the fluid, the reservoir chamber having a fluid outlet and a cover with a first bearing; and a stirring assembly comprising a stirrer located inside the reservoir chamber, the stirring assembly comprising a shaft connected to the stirrer. The stirring assembly can be moved between first and second positions, wherein in the first position the stirring assembly can seal the fluid outlet, the stirring assembly in the first position being configured to form a second bearing with the reservoir chamber or the fluid outlet such that the stirrer can be rotated about an axis defined by the first and second bearing, and wherein if the stirring assembly is in the second position the fluid can pass through the fluid outlet, the shaft being configured to transmit rotational power to the stirrer.
