Abstract: A pipetting device comprising a head and a nozzle with a longitudinal axis mounted to the head is disclosed. An actuator member is arranged around and partially covering the nozzle and coupled to the head or to the nozzle. The actuator member and the nozzle move with respect to each other along the longitudinal axis. A contact member is coupled to and arranged around and partially covering the actuator member. The contact member and the actuator member move with respect to each other. The contact member comprises a rim for contacting a container. The actuator member comprises a rim for opening a cap of the container when the contact member is in contact with the container. The actuator member and the contact member move with respect to each other creating a passage through the cap when the nozzle and the actuator member move with respect to each other.
