Quality Control of Biological Safety Cabinet

Objective To ensure the safety and reliability of using biological safety cabinet(BSC) based on analyzing the quality and performance of BSC.Methods According to the correlative domestic and international criteria,the BSC performance testing content and key projects were analyzed and compared.Results Physical and biological performance tests of BSC included at least leak-tightness of carcass,integrity of high efficiency particulate air(HEPA) filter,airflow velocity of down -flow,airflow velocity of in -flow,airflow pattern,person protection,product protection and cross contamination protection.Conclusion The government should institute laws to regulate quality control of BSC.The laboratory should establish quality management system for periodic checking of BSC.
