What is the difference between a biological safety cabinet and a clean bench?
What is the difference between a biological safety cabinet and a clean bench?1, biological safety cabinet is a microbiology, biomedical, genetic recombination, animal experiments, biological products, biosafety laboratories, and other laboratory biological safety protection isolation equipment, widely used in scientific research, teaching, clinical testing, and production. The main function of the biological safety cabinet is to protect the staff, laboratory environment, and experimental products from exposure to infectious aerosols and spills that may be generated during the operation of primary cultures, bacterial strains diagnostic specimens, and other experimental materials with infectious properties. Its purpose is to protect the experimental process, operators, and the environment from harm.2, the biological safety cabinet is a negative pressure purification bench, the correct operation of the biological safety cabinet, can * protect staff, and test samples and prevent the occurrence of cross-contamination; and the purification bench is only to protect the operation of the object and not to protect the staff and the laboratory environment of the purification bench. Therefore, in microbiology and biomedical research, teaching, clinical testing, and production should choose and use the biological safety cabinet, but can not choose and use the purification bench. 3, purification bench is designed to protect the experimental materials, through the fan will be inhaled air into the primary filter, and through the static pressure box into the high-efficiency filter filtration, the filtered air to the vertical or horizontal airflow state to sent out, so that the operation of the region to achieve the degree of purification of 100, to ensure that the production of environmental purity requirements. Once the microbiological samples are placed in the work area, laminar flow air will be with microbial media air blown to the front of the staff and the danger, so the ultra-clean bench only protects the samples, not protect the operator, the advantages of purification of the workbench is easy to operate, more comfortable, high efficiency, short preparation time, more than 10 minutes after the start can be operated, can be used at any time. |
