Abstract: A device, comprising a unit for taking up a fluid, a unit for emitting electric pulses, wherein said unit for taking up a fluid and said unit for emitting electric pulses are connected with each other via lines so as to form a circuit, wherein there are provided connections for connecting the lines arranged at said unit for taking up a fluid with the lines arranged at said unit for emitting electric pulses in a releasable, hygienic and leakage-free manner. An apparatus comprising the aforementioned device, and a method for treating cells performed with the device or the apparatus, are also disclosed.

Abstract: An antenna (24) for minimizing reception of undesirable signals below a predetermined frequency band includes a first and a second terminal (A, A′) connectable to at least a receiver (22). The antenna components are connected to the first and second terminals, and a filter (26) is integrally connected across the first and second terminals (A, A′). The filter matches an impedance value of the antenna components with an impedance value of the receiver. Moreover, the filter effectively forms a short circuit at the undesirable frequency to minimize reception of undesirable signals below the predetermined frequency band.
