前言二级生物安全柜的一个基本功能就是提供对实验样品或生产产品的保护。它可以保证安全柜外部的污染物不能进入安全柜的工作区域内以及减少对安全柜内使用的其它设备的气溶胶污染。本实验就是在安全柜的前方开口处雾化高浓度的微生物气溶胶来模拟当实验室受到污染时,验证其对实验样品的保护能力。且美国疾病控制与预防中心(CDC)规定Ⅱ级安全柜在BL3级以下生物安全实验室使用要每12个月检测一次,在BL4级实验室使用要每8个月检测一次。由此可见对生物安全柜生物防护性能检测的重要性。
Preface One of the basic functions of a secondary biological safety cabinet is to provide protection for experimental or manufactured products. It ensures that contaminants outside the safety enclosure can not enter the work area of the safety enclosure and reduce aerosol contamination of other equipment used in the safety enclosure. This experiment is to atomize the high concentration of microbial aerosol in front of the safety cabinet to simulate the protection of the experimental samples when the laboratory is contaminated. And the United States Centers for Disease Control and Prevention (CDC) Class II safety cabinets in the BL3 level below the biosafety laboratory to be used every 12 months to test once in the BL4 level laboratory to be tested once every 8 months. This shows the biological safety cabinet biological testing the importance of performance testing.
