在医疗器械行业，通风柜是洁净实验室设备中不可或缺的一部分。为了防止实验室工作人员吸入或吞咽一些有毒的、致病的或未知的化学物质和生物，实验室应通风良好。为了防止吸收一些蒸汽、气体和颗粒，必须通过通风柜、通风橱或局部通风除去污染物。
Difference between fume hood and biosafety cabinet and ultra-clean table
Fume hoods, biosafety cabinets and clean bench are common operating equipment in laboratories. Although they seem to have similarities in structure and appearance on the surface, they are actually three types of devices with different functions. Therefore, it is necessary to know the difference between fume hood, biosafety cabinet and clean bench in laboratory construction.
Biosafety cabinet is a kind of equipment widely used in medical treatment, scientific research, clinical trials and other fields, which realizes the protection of environment, personnel and samples, and is the basic safety protection equipment in the first-class protective barrier of laboratory biosafety.
洁净工作台(超净平台)是为保护实验产品或产品而设计的。垂直或水平的层流空气吹过工作区域，可以防止测试产品或产品被工作区域外的灰尘或细菌污染，对提高产品成品率、精度、稳定性和可靠性有显著作用。
通风柜的目的是保证实验的安全，也是排出有害气体不可缺少的一部分。为了防止实验室工作人员吸入一些有毒的、致病的或未知的化学物质和生物，实验室内应有良好的通风。为了防止吸收一些蒸汽、气体和颗粒，必须通过通风柜、通风橱或局部通风除去污染物。
