CARS was a large, comprehensive space station with a functional focus on scientific research, and storage of dangerous cargo. Besides the large containers used to hold the First Borns, several large laboratories on the lower decks of the space station could be used for routine researches. The samples collected from the First Borns as well as the weird stuff collected from other worlds could all be scanned and analyzed there. Hao Ren did not have to worry about the limited function of the on-board laboratory in the Petrachelys.
