Class I and class II biosafety cabinets of important laboratory equipment

The secondary biosafety cabinet is manufactured by technology, and all functional indexes are strictly tested In order to avoid accidents caused by non professional personnel or improper operation, please strictly follow the following requirements: before any personnel who need to operate and maintain the secondary biosafety cabinet need to receive professional training or authorized permission to operate the instrument, the user must use the language that can be read by the operator and instrument cleaning personnel according to the user manual, use safety records and other technical regulations, Make simple and clear written operation instructions, especially important ones: ● disinfection and cleaning methods of secondary biosafety cabinet and accessories; ● protection measures taken when using special reagents; ● emergency measures to deal with accidents The secondary biosafety cabinet is an important equipment in the microbiology laboratory, which is widely used in the research, teaching, clinical test and production of Microbiology, biomedicine, gene recombination, animal experiment and biological products, especially in the occasions where the operators need to take protective measures It adopts the current advanced air purification technology and negative pressure box design to realize the protection of environment, personnel and samples, such as medical treatment, pharmacy, scientific research, etc to provide a sterile, dust-free and safe working environment for bacterial culture; the secondary biosafety cabinet can be divided into single-sided, double-sided, single-sided according to the use function, and the exhaust mode can be divided into half exhaust and full exhaust; the secondary students The material safety cabinet is made of steel and wood structure The whole machine is designed with humanization and plug-in The secondary biosafety cabinet is a kind of negative pressure filter ventilation cabinet to protect people, products and environment The front opening of the inward air flow plays a protective role for people The vertical downward HEPA (ULPA) filter layer air flow can protect products, and the polluted air flow can protect the environment after being filtered by HEPA (ULPA) filter When it is used in microbial experiments with trace volatile toxic chemicals and trace radionuclides as adjuvants, it needs to connect the exhaust hoods with appropriate functions
