MERLIN (refrigerator)

• MERLIN is cooled using Thermoelectric elements, and can be cooled to -20 °C while using ISS water supply or -10 °C while only being air cooled. Resistive heating elements are used to provide an incubation capacity up to 48.5 °C.
• MERLIN contains temperature sensor connections inside the payload volume, for monitoring sample temperature, for up to 12 sensors.
• The internal sample volume is ~0.65 cubic feet (0.018 m³).

MERLIN is one of multiple units available for storage on the ISS and/or transportation to and from the ISS.
