An animal cage is described suitable for automated use in a vivarium. The cage comprises a study animal; bedding; pathogens; a wireless, a sterilizable scale comprising a sterile case comprising a flexible, penetrated membrane; and a penetrating fastener penetrating the membrane. The comprises four internal volume areas with respect to pathogen content: (1) volume between the membrane and a weighing platform, free of bedding; (2) a sterile volume inside the scale case below the membrane; (3) a vertical channel fluidly connecting the inside of the cage with the first volume; and (4) the inside of the cage outside of the above three volumes. These four volumes are sterilely isolated from air outside the cage. Electronics in the scale communicate wirelessly, through the cage, to cage-associated electronics outside the cage, using narrow beam communications free of device-ID specific protocol. The scale may be disassembled, sterilized in a fluid, re-assembled, and re-used in a different cage.

The invention provides an animal cage. The animal cage comprises a bottom plate, a cage body and a food and drink bowl. The cage body comprises an outer screen frame, an inner screen frame, isolation screen frames, a screen frame cover and a base. The base is mounted on the bottom plate and provided with multiple grooves. Animal excrements fall into the bottom plate through the grooves. The isolation screen frames divide the cage body into multiple small cages, so multiple animals can be raised simultaneously. The food and drink bowl comprises a food inlet, a water inlet, bubblers, food outlets and a food and drink bowl body. The food and drink bowl body is of a double-layer structure, food is placed in the inner layer, and water is placed in the outer layer, so feeding of the animals is facilitated; the food and drink bowl is detachable and convenient to clean. The animal cage is simple in structure, attractive in appearance and capable of raising multiple animals simultaneously.

A sterile scale is described suitable for automated use in animal cages. A case is covered by a flexible membrane that provides both sealing against pathogens and mechanical compliance for transfer of weight on an above weighing platform through a single sealed penetration in the membrane to a load cell in the case. The membrane comprises a perimeter that is attached and sealed to the case with a membrane frame, a penetration area, penetrated by a rigid weight-bearing element, and an isolating compliance area. A skirt on the weighing platform surrounds the case, protecting detritus from entering from below onto the membrane, while providing open-air movement. The weighing platform and case are easily separated permitting fluid-based sterilization of both. The weight-bearing element may contain an electrical connection from the case to the platform, through the membrane.

Heat exchanger assemblies and methods are provided for cooling the interior of an enclosure (e.g., electrical cabinets, computer server racks, chemical chambers, and animal cages). Heat is transferred via thermal conduction from a first plurality of surfaces positioned inside the enclosure to a second plurality of surfaces positioned outside the enclosure. The first and second plurality of surfaces remain in thermal contact with one another during use. Heat is dissipated from the second plurality of surfaces to the ambient air outside the isolated environment without the ambient outside air mixing together with the air inside the enclosure. This, in turn, inexpensively removes heat from the air inside the enclosure and prevents contaminants from entering the enclosure.
