At this time, the three-way valve 11 is opened to the Hepa filter 9 side and the blower 12 is driven. and,
While the rotor 4 is rotating, the air in the rotor chamber 3 is forcibly exhausted to the outside through the Hepa filter 9 as shown by the arrow in the figure, thereby maintaining the pressure in the rotor chamber 3 below atmospheric pressure. During the centrifugal separation operation by the rotor 4, the solenoid valve 17 maintains a closed state. After the centrifugation operation is completed, the solenoid valve 17 is opened and external air is sent into the rotor chamber 3 through the dust filter 18, while aerosols in the dirty air are captured by the Hepa filter 9. As a result, the inside of the rotor chamber 3 is ventilated and cleaned with fresh air. Next, when sterilizing the inside of the rotor chamber 3, the solenoid valve 17 is closed and the three-way valve 11 is switched to the sterilizing gas generator 13 side. Then, a sterilizing gas such as formalin is generated from the sterilizing gas generator 13 and supplied to the rotor chamber 3, and is circulated as indicated by the dotted line arrow in the figure to sterilize various germs in the rotor chamber 3. The interior of the rotor chamber 3 may be sterilized by the sterilizing gas generator 13 depending on the sample. In addition,
Depending on the sample, the sample and the like in the rotor 4 may be taken out after being cleaned with air or after being sterilized with sterilizing gas. The sample leaked from inside the rotor 4 into the rotor chamber 3 during centrifugation is treated with disinfectant solution 1.
The sample aerosol is sterilized when the sterilizing gas passes through the sealed container 14.

とができる。 As described above, according to the centrifugal separator according to the present invention, during centrifugation operation using the rotor, the air in the rotor chamber is forcibly exhausted to the outside through the Hepa filter by the blower, and the pressure in the rotor chamber is reduced to atmospheric pressure. In other words, since it is maintained in a negative pressure state,
There is no risk of aerosol leaking directly from the rotor chamber to the outside. On the other hand, since aerosols in the air in the rotor chamber exhausted by the blower are completely captured by the Hepa filter, biological damage to the operator can be completely prevented. Furthermore, since the rotor chamber can be maintained at a pressure slightly lower than atmospheric pressure, centrifugation can be performed under almost the same conditions as in the atmosphere. Furthermore, since the sterilizing gas can be supplied to the rotor chamber by simply switching the switching valve, the inside of the rotor chamber can be sterilized without opening the rotor chamber. At this time, the pipe on the blower side is closed, so the sterilizing gas circulates between the sterilizing gas generator and the rotor chamber to sterilize the rotor chamber, so there is a risk that the sterilizing gas will be wasted during sterilization. There is no such thing. In addition, during the centrifugation operation,
In the unlikely event that a sample leaks from inside the rotor into the rotor chamber, it will be discharged into a sealed container containing disinfectant and sterilized, and the aerosol of the sample will be completely sterilized as sterilizing gas passes through the sealed container. Therefore, compared to conventional centrifuges, more reliable sterilization can be performed.
