Radiosynthesis of [1-11C]acetate is well described in literature, but all syntheses either require adaptations in complex commercial synthesizers or rely on closed-source hardware and software control. Arduino microcontrollers are ideal for the compact, flexible, and inexpensive control of low-complexity hardware, making them particularly suited for radiochemistry where operation in space-limited shielded hot cells is mandatory. We established a [1-11C]acetate radiosynthesis module for combination with a [11C]MeI module available in almost every lab working with 11C. Its small footprint even enables back-to-back production in a hot cell already occupied by other modules. Using this setup, we achieved a reliable and flexible supply of this tracer, with radiochemical yields of 51.4 ± 28.2% and radiochemical purities (RCPs) of 94.4 ± 6.7% ( n = 9) in a synthesis time of 15 minutes. Positron emission tomography (PET) and biodistribution analysis demonstrated low background uptake in healthy mice, with highest uptake in liver and kidneys. Arduino microcontrollers have become valuable and versatile tools in our lab for the automatization of low-complexity procedures not requiring full-blown commercial radiochemistry synthesizers, as showcased here for the production of [1-11C]acetate.
