Biosafety laboratory refers to a series of protective barriers and management measures to avoid or control the hazards of pests and factors that are operated, so as to meet the requirements of biosafety, so that the laboratory can be used to carry out research in the fields of microbiology, biochemistry, biomedicine, animal experiments, etc., because the samples of biosafety level 3 and 4 laboratories (BSL-3/4) test are highly contagious and virulent infection to humans and sounds, in order to ensure that the laboratory is always in a state of standby without pathogenic bacteria, In the past, formaldehyde purification would cause long-term pungent odors, white crystals that were difficult to remove and corrosion risks, so more and more biosafety laboratories used dry hydrogen peroxide for purification.

        Specifically, the disinfection of biosafety laboratories, especially the disinfection of work surfaces, plays a very important role in the good operation of biosafety laboratories and the protection of staff. On the one hand, laboratory workers need to be exposed to infectious pathogens, which can easily cause laboratory infection events; On the other hand, it is difficult to avoid the generation of aerosols in the experimental operations of pathogenic microbiology laboratories, such as sample mixing, suction and blowing, centrifugation and transfer, and opening bottle (tube) caps, which may contaminate the operating environment, resulting in cross-contamination between test samples and affecting the reliability of test results.

Traditional disinfectants such as 84 disinfectant, new Jieer extinguishing and other chemical disinfectants have a good disinfection effect on the laboratory work surface, and the bacterial killing rate can generally exceed 95%, but 84 disinfectant and new Jieer disinfection will produce residues after disinfection, and the laboratory will have a certain pungent odor after use. When the new Jieer extinguishes the disinfection of the work table, one will only disinfect the front and the visible side, resulting in the bottom of the workbench and the position that is not easy to disinfect will leave a disinfection dead end, which will affect the overall disinfection effect and bring potential safety hazards, hydrogen peroxide solution is chemically active, easy to decompose into oxygen and water, no residual toxicity, so hydrogen peroxide disinfection will not cause secondary pollution to the environment, known as the cleanest disinfectant, in addition to being widely used in the field of biochemistry as a strong oxidant, The super oxidation ability of hydrogen peroxide can also destroy the protoplasm in the microbial body, so as to achieve the effect of killing microorganisms, and it has a good killing effect on bacterial propagules, fungi and bacterial spores.

Therefore, as a new type of laboratory disinfection equipment, the vaporized hydrogen peroxide generator can vaporize the liquid peroxide gas in accordance with the specified disinfection procedures to complete the laboratory disinfection, and the vaporized hydrogen peroxide generator adopts food-grade peroxide gas, and the disinfection process is automated, so it is non-toxic and harmless to the staff, and will not cause damage to the laboratory workbench and experimental instruments, and at the same time disinfect the laboratory workbench thoroughly and leave no dead ends. Among them, the mobile gasification hydrogen peroxide space purification system has the advantages of easy mobility, real-time monitoring of the purified environment (temperature, humidity, hydrogen peroxide concentration), and compliance with various laws and regulations, and is widely used by BSL-3/4 in Chinese and foreign countries.
