Currently, the high-precision Penning trap mass spectrometer PENTATRAP is being built up at the Max-Planck-Institut für Kernphysik, Heidelberg, Germany. It aims at mass-ratio measurements of medium- to high-Z elements with uncertainties of a few parts in 1012. Mass-ratios will be determined by the measurement of cyclotron frequency-ratios in the strong magnetic field of the trap. The experiment will host five identical cylindrical Penning traps and will allow for simultaneous cyclotron frequency determinations in all measurement traps. It will feature access to highly charged ions provided by EBITs. Measurements at PENTATRAP will contribute to various fields of physics. For example, input parameters for neutrino mass determinations will be provided with measurements of Q-values of relevant β-transitions. The current status of the experiment will be outlined in the talk.
