The Minus Eighty Degrees Celsius Laboratory Freezer for ISS [International Space Station](MELFI) is a fully integrated rack facility, hosted in an ISPR [International Standard Payload Rack], to condition, freeze and store life sciences and biological samples aboard the Space Station. MELFI will also be used to transport frozen specimens to/from the Station flying fully powered inside the Mini-Pressurised Logistic Module aboard the Space Shuttle.... MELFI characteristics :[a] Volume : 300 litres total in 4 independent dewars(minimum configuration 1 dewar at-80 °C; 2-4 dewars in combinations of 3 modes : below-68 °C,-37 °C to-23 °C, +0. 5 °C to +6 °C; [b] Temperatures maintained for 8 hours without power Sample storage : cell culture 1-10 ml, fluids(blood, media, etc.) 1-500 ml, tissue 2-10 ml, whole specimens 10-500 ml Cooling time(from +23 °C to-68 °C) : 2 ml 18-25 min; 10 ml 44-56 min; 500 ml 460 min.

MELFI [Minus Eighty degree celsius Laboratory Freezer for ISS] est un congélateur/réfrigérateur destiné à la Station spatiale internationale et plus particulièrement aux modules américains (USLab) et japonais (Japanese Experiment Module : JEM). MELFI permet le refroidissement et le stockage d'une large variété d'échantillons (de 2 à 1000 ml) issus des différentes expériences de science de la vie menées à bord de l'ISS [International Space Station]. Le volume de stockage des échantillons est de 300 litres répartis en quatre enceintes froides (dewars) pouvant fonctionner indépendamment et à trois niveaux de température différents (+4 °C, -26 °C et -80 °C). La production de froid est assurée par une machine cryogénique fonctionnant selon le cycle thermodynamique de Brayton [...] Un circuit d'azote permet d'assurer la distribution du froid vers les enceintes froides.

The Material Science Laboratory(MSL) offers a multi-user capability to support scientific research in solidification physics, crystal growth with semi-conductors, measurement of thermophysical properties and the physics of liquid states. MSL occupies about half of an ISPR [International Standard Payload Rack] in the US Lab, and one ISPR in the Columbus Laboratory. The two MSL versions are identical except for minor rack interface differences. Each MSL comprises a core element consisting of a sealed process chamber in which interchangeable furnace inserts are hosted. These inserts process the samples. The sample cartridges are manually loaded into one of the furnaces. The furnace can be moved over the sample cartridge to displace the thermal gradients. Diagnostic systems provide scientific data on the facility and sample cartridge during operations. As the furnaces are modular, they can be upgraded or replaced according to utilisation needs. Additional MSL units complete the accommodation and operational interfaces to the laboratory.

CONT

The MSL will be developed in two versions: Facility 1, to be accommodated within the US Laboratory Module of the International Space Station; and Facility 2, to be accommodated on board the European Columbus Laboratory. These two facilities are very similar to each other; the main differences being that the US Laboratory version of MSL is accommodated inside the NASA Materials Science Research Rack. This rack is equipped with the Active Rack Isolation System ARIS, which provides a modicum of isolation from microgravity disturbances.
