Abstract

A fluid manipulation head (200) for aspirating and / or dispensing a fluid, comprises at least a first needle (201), a second needle and a sealing structure for sealing a first and a second needle receptacle (521) of a cleaning station (500), when the first needle (201) and the second needle are accommodated in the first and the second needle receptacle (521) respectively. The sealing structure comprises an opening, wherein a first longitudinal axis of the first needle (201) and a second longitudinal axis of the second needle extend through the opening of the sealing structure. A cleaning station (500) for cleaning a needle of a fluid manipulation head (200) comprising a first opening for a first receptacle (521) and a second opening for a second needle receptacle, wherein the cleaning station (500) further comprises a counter sealing structure for interacting with a sealing structure of a fluid manipulation head, wherein the counter sealing structure comprises an opening, wherein a first longitudinal axis of the first needle receptacle (521) and a second longitudinal axis of the second needle receptacle extend through the opening of the counter sealing structure. A method for cleaning at least a first needle (201) and a second needle of a fluid manipulation head (200) using an arrangement comprising a fluid manipulation head (200) and a cleaning station (500), the first needle (201) and the second needle are accommodated in a first and a second needle receptacle (521) of the cleaning station, wherein the first and a second needle receptacle (521) of the cleaning station (500) are sealed by contacting the counter sealing structure with the sealing structure.
