Device for Inhalation Exposure of Animals to Spores

Summary

A culture flask with 10 side arms is converted by insertion of a unit for blowing air across a fungus culture into an exposure chamber. Ten mice or other animals can be exposed simultaneously with minimal contamination to an atmosphere containing dry spores. The design can be adapted to exposure of larger animals and to use with dusts, mists and gases. Superior features of the device are: it is small and portable, it is simple in construction and operation, it is a closed system, and contamination of fur of animals is minimal.
