Abstract
An automated cell culture system with one or more pumps configured to operate on a duty cycle prevents excess heat generation, allowing the cell culture system to operate inside a conventional incubator without overheating. The duty cycle involves switching the pump between on and off modes. By running pumps for a short period of time and then shutting them off, less heat is produced. To account for the reduced pumping time during the cycle, the pump can be run at a higher flow rate while it is on, so that the average flow rate over the course of the cycle is not reduced. Systems of the invention employ duty cycles in which the on-cycle is shorter than the off-cycle, and particularly where the on-cycle is less than 20% of the duration of the entire duty cycle.
