Preparation of biological samples in space: the experiment preparation unit

The Experiment Preparation Unit (EPU) is a facility that prepares biological samples for their upcoming experiment within Biolab (Columbus). For logistical reasons and to avoid the influence of the heavy launch loads and the microgravity environment before the actual initiation of the experiment, biological samples will be sent cryogenically frozen to the International Space Station. The Experiment Preparation Unit will prepare those samples by thawing and extracting the cryogenic fluid automatically after minimal crew intervention for set-up of the system. The EPU can be tele-operated directly from ground and consists of three major subsystems to guarantee its functionality: Functional Platform, Base and Control Panel.
