* This device is a gas -rugged device for the purpose of returning bacteria or vapor chemicals for bacterial chemicals. The test method is exposed to testing substances under the existence and non -existence of the metabolic activation system, then sowed in the minimum agar medium to a flat plate to cultivate appropriate periods. It is compared to the recovered variant of the recurrent variant colony and grows on a flat flat plate, and is set with a test material generator and a glass -dewed chamber.
