Corvane ships small, valuable batches for clinical trials that must stay between 2 and 8 °C and arrive on a fixed day. We collect in validated boxes, screen the freight in our own shed at the airport and book it on the evening flight. Our Chicago broker files the entry while the aircraft is over the Atlantic, and a courier meets it on the apron. The median time from the lab door to the clinic is 36 hours, and every box travels with a logger.
