生物安全柜性能解疑

“生物危害（Biohazard）”定义生物性的传染媒介通过直接感染或间接破坏环境而导致对人类、动物或者植物的真实或者潜在的危险。“实验室生物安全”一词用来描述那些用以防止发生病原体或毒素无意中暴露及意外释放的防护原则、技术以及实践。

摘要 在2000年5月，欧洲标准化委员会(CEN)颁布了生物安全柜欧洲标准EN12469:2000，正式替代了德国DIN 12950、英国BS5726和法国NF X-44-201等欧盟成员国生物安全柜的标准，成为欧盟区域内生物安全柜的统一标准。 NSF49在上世纪70年代就已经出现，被公认为目前生物安全柜领域最完善的标准。在2002年，ANSI/NSF49正式获得了美国国家标准学会（American National Standard Institute, ANSI）的官方认可，成为美国生物安全柜的统一标准。 EN12469和NSF49是目前世界生物安全柜领域最重要的标准，在这篇文章中，我们会着重介绍和讨论两项标准之间的区别，以供业内人士参考。

The Esco Formalin Vaporizer (FVP-00X) is a microprocessor-controlled unit that simplifies and automates the decontamination process for all sizes and makes of biohazard safety cabinets. This also increases safety for the decontamination operator and laboratory personnel since no manual intervention is required during the entire process. The unit enables decontamination to be accomplished by the standard protocol as recommended in EN12469 (European standard for microbiological safety cabinets) with formalin and ammonia solutions. ANSI/NSF49 (American standard for Class II cabinets) recommends decontamination using paraformaldehyde and ammonium bicarbonate which is a similar protocol but with agents in the solid (instead of liquid phase), and as such this vapouriser can also be said to be in compliance with the ANSI/NSF49 recommended decontamination protocol.
