“Close system” and “flow system” are proposed as the test methods for fumigation against the microorganisms.
When the “close system” is employed, the volume of fumigation vessel used for the test should be 1 to 2 liter and the fumigants should be injected into this vessel at the gasphase. When the above method is in operation, the gas distribution in this vessel becomes even immediately.
Therefore, the quantitative expression of a sterilization effect is possible. When the “flow system” is employed for the test of a fumigant with a low boiling point, the apparatus to be used is shown as Fig. 2. On the other hand, the apparatus illustrated in Fig. 3 is used for fumigants with higher boiling points.
These apparatuses of Fig. 2 and 3 are recommended for quantitative expressions such as comparison of the sterilization effect of various fumigants or microorganisms and the probabilitical study of sterilization mechanisms.
