There is a growing need for detailed laboratory data in order to understand and model the formation and destruction of matter in a variety of environments, ranging from very cold dense interstellar clouds via planetary atmospheres to the high temperatures of circumstellar environments. In this report we summarize recent progress made with special instruments the central devices of which are specific ion or nanoparticle traps. Today, temperature variable 22-pole traps are used routinely in several laboratories in the fields of reaction dynamics and spectroscopy. Recent results from such experiments are briefly mentioned including reactions with carbon radicals or slow hydrogen atoms and isotope fractionation. Traps are also well suited for studying matter at temperatures of several thousand K. In the second part of this contribution we report results from rf traps, in which an ensemble of charged particles is exposed to the radiation of a pulsed or continuous laser. First successful tests have been performed with C60+. Besides thermal stability of hot interstellar grain equivalents the method allows to explore their growth in a suitable gaseous environment.
