Abstract: Many samples of current interest in molecular physics and physical chemistry exist in the liquid phase and are vaporized for use in gas cells,diffuse gas targets, or molecular gas jets. For some of these techniques, the large sample consumption is a limiting factor. When rare, expensivemolecules such as custom-made chiral molecules or species with isotopic labels are used, wasting them in the exhaust line of the pumps isquite an expensive and inefficient approach. Therefore, we developed a closed-loop recycling system for molecules with vapor pressures belowatmospheric pressure. Once filled, only a few valves have to be adjusted, and a cold trap must be moved after each phase of recycling. Therecycling efficiency per turn exceeds 95%.
