Abstract

Pipette head (1; 86) having, for receiving a suspension by suction, at least one suction channel (3; 87) which can be connected to a suction means (43) and opens into a pipette opening (7; 88), wherein in the direction of suction flow before the pipette opening (7;88) at least one filter module (23, 29; 57) covering at least the pipette opening (7; 88) with an end side (27; 62) is detachably held in such a way that the suspension is passed during suction through a filter element (26, 32; 70) of the filter module (23, 29; 57), the pipette head (1; 86) having at least one flushing channel (14; 90) which can be connected to at least one flushing means (44) and the free end of which is associated with the end side (27; 57) of the filter module (23) in such a way that liquid and/or gaseous flushing medium conveyed through the flushing channel (14; 90) by means of the flushing means (44) flows through the filter element (26, 32; 70) of the filter module (23, 29; 57) counter to the direction of suction flow. Furthermore, the invention relates to a filter module (57), an automated pipetting device, the use of a pipette head (1; 86) and a method for operating a pipette head.
