An Exhaust Hood for Animal Perfusions.

Animal perfusion is a common technique in the physiology research laboratory and typically involves the use of aqueous formaldehyde. Depending on the specific procedure conducted, the animal studied, and availability and efficiency of local ventilation systems, these procedures may create occupational over-exposure to formaldehyde, a regulated carcinogen. We report the design and performance of a local exhaust hood specifically developed for primate and small mammal perfusion.
