On July 25, 2017, Shenzhen Kangfeng Environmental Technology Development Co., Ltd. medical air disinfection and purification equipment YKJ1000F-A01 conducted a sterilization rate test in the Ou Guangshuo laboratory of the School of Life Sciences, Tsinghua University.

        Tsinghua University's scientific research strength is second to none in the country, and it has a pivotal role in the world. Ou Guangshuo laboratory is the top laboratory in China. The laboratory focuses on nematode Q neural precursor cells to study how the cytoskeleton and signal transduction proteins regulate the development of the nervous system. An in vivo fluorescence microscopic imaging method was established to record the Q cell development process in real time at the organelle and molecular level.

        For disinfection methods, Ou Guangshuo laboratory currently uses a dual disinfection and sterilization method of laminar flow technology and ultraviolet lamp irradiation. Even after such treatment, the average number of colonies in the environment is still 0.75cfu/15min·Φ60mm.

        The number of colonies in the environment is 0 when the air disinfection and purification equipment of Kangfeng Environment is running for 30 minutes, and it is still 0 when running for 60 minutes, and it has been maintained. The sterilization ability that is so stronger than the laminar flow plus UV lamp is benefited from Kangfeng Environmental's core patented technology AOP-KF® solid base. The ability of the solid base to disinfect and sterilize and remove microorganisms is currently leading the world. There are many sterile laboratories, in addition to bacteria are also plagued by mold. Kangfeng's solid alkali technology has a good killing effect on these bacteria, molds and spores. After all, in a sterile laboratory, the best means of disinfection and sterilization should be used, right?

experiment procedure

1) Put the sterilizing and purifying machine (YKJ1000F-A01) into the cell room, close the door and window, select the collection plate and place it, and collect the plate after 15 minutes, as the test sample before the test.

2) Turn on the medical disinfection and purification machine, and start timing. After 30 or 60 minutes, press 1) to place the collection plate. After 15 minutes, collect the plate and use it as a test sample after the test. Turn off the machine.

3) Follow the steps 1) and 2) outside the cell to perform laboratory decontamination and sterilization tests without closing the doors and windows.

4) During sampling, the collection plates are placed evenly and placed at a height of 0.8 m from the ground.

5) Take 4 unused batches of the same batch of culture medium and culture them with the sampled samples at the same time as a negative control.

6) Place the petri dish in a 37±1℃ constant temperature incubator for 48 hours and then take it out to check the number of colonies.
