Containers utilizing economical gas-permeable, ultra-thin dense skin polydimethylsiloxane membranes incorporating porous substrates as passive contaminant barriers in containment systems for research, breeding, housing, and shipping of animals, including fish, birds, and mammals, and plants, or animal, plant or microbial cells. These membranes protect the animals from airborne pathogens while permitting exchange of respiratory gases and metabolic heat, as well as protect laboratory personnel, mail handlers, and others who come in contact with or transport the animals from animal borne allergens and infectious agents.
