Claim 0:
1. A dispenser cassette (11) that releasably attaches to a peristaltic pump, said dispenser cassette comprising:
an output cartridge (13) that is adapted to be mounted to the peristaltic pump;
an intake cartridge (15) that is adapted to be mounted to the peristaltic pump;
pumping tubes (19), which are accommodated in the dispenser cassette (11) such that an output end of each pumping tube is inserted in the output cartridge and an intake end of each pumping tube is inserted into the intake cartridge;
an elastic connector (33) connected between the output cartridge and the intake cartridge such that the output cartridge and intake cartridge are able to move in relation to one another, said pumping tubes between the output and intake cartridges being shorter than the elastic connector such that the elastic connector is located apart from the pumping tubes and lies outside of the pumping tubes; and
nozzles for dispensing liquid from the pumping tubes, wherein each nozzle is attached on the output end of the respective pumping tube inside the output cartridge;
wherein, when the dispenser cassette is attached to the peristaltic pump and rotors in the peristaltic pump are rotating to pump liquid, the pumping tubes are stretched over the rotors and liquid is conveyed through the pumping tubes by external deformation of the pumping tubes by the rotors without pressing the pumping tubes against a wall, and the liquid is dispensed through each pumping tube through the respective nozzle.
