Differences among biosafety cabinet, super clean workbench and ventilation cabinet

Differences among biosafety cabinet, super clean worktable and ventilation cabinet product protection operator protection sample protection environment biosafety cabinet yes no super clean worktable Whether the fume hood is clean air type fume hood is air isolation device or not It can be seen that the biosafety cabinet, as a kind of safety protection product, has strong protection strength and is suitable for high-risk experiments The fume hood is suitable for the experiment that the sample is not afraid of cross infection, and the super clean table is suitable for the experiment that the sample is harmless to human body Specific differences I biosafety cabinet biosafety cabinet (secondary biosafety cabinet) is used to protect the operator, laboratory environment and experimental materials when operating infectious experimental materials such as primary culture, bacterial strains and diagnostic specimens To avoid exposure to infectious aerosols and splashes that may occur during the above operations Type: Class III 6854 operating room, first aid room, diagnosis and treatment room equipment and appliances II Clean bench is designed to meet the needs of modern industry, photoelectric industry, biopharmaceutical and scientific research and test fields for the cleanliness of local work area The super clean workbench can only protect the reagents operated in the workbench from pollution and does not protect the workers The air supply mode of super clean worktable is mainly vertical flow air and horizontal flow air! ① Horizontal flow: it is a kind of universal local clean working table, which is widely used in electronics, national defense, precision instruments, instruments, pharmaceutical industry, etc ② Vertical flow: the vertical unidirectional flow super clean bench is widely used in areas requiring local cleaning Laboratory, biopharmaceutical, photoelectric industry, microelectronics, hard disk manufacturing and other fields Type: Class II 6857 disinfection and sterilization equipment and apparatus of medical device products; III fume hood or fume hood With exhaust function, it can reduce the contact between the experimenter and the harmful gas, prevent the harmful gas, odor, moisture and flammable, explosive and corrosive substances produced in the experimental operation from causing harm to the experimenter, so as to protect the laboratory staff Type: normal
