前言二级生物安全柜除了提供对实验样品或生产产品的保护和对操作人员的保护以外。它还应该对安全柜内使用的其它仪器或器材减少气溶胶的污染。即在安全柜内一边产生的污染气溶胶不致扩散到另一边。通过这个实验可以验证安全柜内垂直平行流的气流情况。本实验就是在安全柜内的两侧分别发生气溶胶来检测当柜内产生高浓度的微生物气溶胶时,安全柜对在其内部使用的其它仪器或器材的保护能力。材料方法1、喷雾悬液的制备:制备方法同人员保
Foreword Class II biological safety cabinets in addition to providing experimental samples or product protection and protection of the operator outside. It should also reduce the aerosol pollution of other instruments or equipment used in safety cabinets. That is, the aerosol generated inside the safety cabinet will not spread to the other side. Through this experiment can verify the safety cabinet vertical parallel flow of air conditions. In this experiment, aerosols respectively occur on both sides of the safety cabinet to detect the protection ability of the safety cabinet against other instruments or equipment used internally when the cabinet produces high concentrations of microbial aerosols. Material Method 1, the preparation of spray suspension: preparation method with the staff Paul
