ABSTRACT:
A hose cartridge for a peristaltic pump comprises a cartridge housing provided with a lateral recess. The recess is delimited at least partially by an element having essentially the shape of a segment of a circle. A roller wheel of the peristaltic pump can engage that recess once the cartridge is attached to the peristaltic pump. The cartridge housing is provided with two support arms, and a groove extends from one of the support arm along three outer side faces of the cartridge housing to the other support arm. The ends of the support arms are provided each with a hose take-up member for retaining stoppers attached to a hose section. Such a hose cartridge is of very compact design ensures an easy handling.
