The IGISOL facility at the Department of Physics of the University of Jyväskylä (JYFL) is delivering radioactive beams of short-lived exotic nuclei, in particular the neutron-rich isotopes from the fission reaction. These nuclei are studied with the nuclear spectroscopy methods. In order to increase the quality and sensitivity of such studies in a meaningful way the beam should undergo beam handling: cooling, bunching and isobaric purification. For this purpose an ion trap system, JYFLTRAP, was constructed. The first two processes are performed with the use of an RFQ cooler/buncher. The isobaric purification is made by a Penning trap placed after the RF-cooler. This will yield a substantial background reduction in the nuclear decay spectroscopy experiments and enable studies of very exotic nuclei, like the ones belonging to r-process path. This contribution describes the current status of the Penning trap project including the results of its off-line and on-line tests.
