目的评价实验室生物安全柜对微生物污染控制的效果。方法采用人工染菌和采样检测方法,检测和评价实验室生物安全柜在交叉污染、产品保护和人员保护测试方面的防护效果。结果交叉污染测试结果,细菌总数分别≤1 cfu/次;产品保护测试结果,细菌总数≤1 cfu/次;人员保护测试结果,撞击式采样器采集到细菌总数为2cfu/次,狭缝式采样器采集到细菌总数均为≤1 cfu/次。结论本次检测的生物安全柜的安全性能指标符合国际通用要求,具有较好的安全性。
Objective To evaluate the effect of laboratory biological safety cabinet on microbial contamination control. Methods The methods of artificial contamination and sampling were used to detect and evaluate the protective effect of laboratory biological safety cabinets on cross-contamination, product protection and personnel protection testing. Results The results of cross-contamination test and total number of bacteria were ≤1 cfu / time respectively. The results of product protection test and total bacteria count ≤1 cfu / time. The results of personnel protection test showed that the total number of bacteria collected by impact sampler was 2 cfu / The total number of bacteria collected were ≤ 1 cfu / times. Conclusion The safety performance indicators of the biological safety cabinets tested in this test meet the international requirements and have good safety.
