When a laboratory operator operates the sterilizing device of the present invention, firstly, the cylinder 2 is put into a container (for example, the following outer cup 1) for holding sterilizing liquid, then, experimental materials are put into the cylinder 2, then, sterilizing liquid is injected into the outer cup 1, after the injected sterilizing liquid reaches a certain height, the movable filter screen sheet 3 is put into the cylinder 2 through the operating member 4 until the experimental materials are fully immersed into the sterilizing liquid, then, the movable filter screen is lifted up by pulling the wire, then, the experimental materials are put down, and the operation is repeated for several times, so that the experimental materials are fully sterilized (first sterilization) in a short time. After the first disinfection is finished, the movable filter screen sheet 3 is kept in a state of being parked in the cylinder body 2, the disinfection liquid in the outer cup body 1 is poured out, then new disinfection liquid is continuously injected into the outer cup body 1, and the second disinfection is started when the experimental material is fully immersed into the new disinfection liquid. After the sterilization work is completed completely, under the condition that the verification material is not overflowed out of the cylinder 2 due to floatation (for example, the height of the cylinder 2 is set high enough so that the liquid level of the sterilization liquid is always in the cylinder 2, or the cylinder 2 together with the movable filter screen sheet 3 is lifted upwards so that the liquid level of the sterilization liquid is not higher than the upper opening of the cylinder 2), the movable filter screen sheet 3 is pulled out of the cylinder 2 through the operation member 4 and the movable filter screen sheet 3 is kept in a state of leaving the cylinder 2, then the cylinder 2 is taken out, the verification material is taken out, and finally the sterilization liquid in the outer cup 1 is poured out. During disinfection, the movable filter screen 3 can press the experimental material below the liquid level of the disinfection liquid, so that the experimental material can be blocked by the movable filter screen 3 and cannot be poured out along with the disinfection liquid when the disinfection liquid is poured out. In addition, after the sterilization work is completed, the experimental materials are usually sorted by using the apparatus by one hand, and the placing vessel by the other hand, so that the movable filter screen sheet 3 needs to be kept away from the cylinder 2, so that the sorting work can be performed by two hands of an operator.

The operation member 4 may be provided in various forms as long as it is capable of keeping the movable filter screen 3 away from the cylinder 2 when necessary, and for example, the operation member 4 may take the form of: the operating member 4 is a rod-shaped member having a first end and a second end, the first end being disposed above the cylinder 2, the second end being disposed outside the cylinder 2; a stay wire is arranged at the first end, one end of the stay wire is connected with the movable filter screen piece 3, and the other end of the stay wire is provided with a circular ring; the second end is provided with a hook matched with the circular ring; the ring has a hooked state in which it is connected to the hook and brings the operating member 4 into a locked state, and an unhooked state in which it is disconnected from the hook and brings the operating member 4 into an unlocked state. When the operator pulls the ring, the movable filter screen sheet 3 moves away from the cylinder 2 and finally leaves the cylinder 2, and in order to keep the movable filter screen sheet 3 in a state of leaving the cylinder 2, the ring is hung on the hook after the movable filter screen sheet 3 leaves the cylinder 2, so that the ring cannot return to the initial position, that is, the movable filter screen sheet 3 cannot return to the cylinder 2 any more. It should be understood that the length of the pull wire should be set to: when the ring is hung on the hook, the movable filter screen 3 is in a state of leaving the cylinder 2.

It can be seen that the cartridge 2 must be placed in a container capable of holding a sterilizing liquid in order to soak the test material therein in the sterilizing liquid, and therefore, as shown in fig. 2 and 3, it is preferable that the sterilizing device comprises an outer cup 1 having an upper opening and capable of being placed in the cartridge 2, and that the upper opening of the cartridge 2 is provided with a first handle 21 which is stopped against the upper opening of the outer cup 1 when the cartridge 2 is placed in the outer cup 1. After the sterilization is completed, the cylinder 2 can be taken out of the outer cup 1 by holding the first handle 21 by hand, and the effect of preventing contamination can be achieved without using tools such as tweezers.
