Biosafety Laboratory
Microbiological safety laboratory control system mainly includes a constant-temperature and constant-humidity control system, an air supply and exhaust control system, a room differential pressure and differential pressure gradient control system, a disinfection control system, an illumination control system, a sound-light alarm system, a monitoring system, etc.
Microbiological safety laboratory refers to a microbiological laboratory meeting the requirements of microbiological safety through protective barriers and management measures, which includes a main laboratory and its auxiliary rooms. Microbiological safety laboratory is divided into four levels, BSL-1, BSL-2, BSL-3 and BSL-4, according to the biological hazard degree and protection measures taken for the processed objects in the laboratory. The basic task of a microbiological laboratory automatic control system is automatic adjustment at any moment to ensure the correctness of key parameters of biosafety laboratory, so that experimenters cannot be threatened by the experimental environment, and pathogenic microorganisms cannot be leaked to the external environment.
