在醫療器械行業，通風柜是潔凈實驗室設備中不可或缺的一部分。為了防止實驗室工作人員吸入或吞咽一些有毒的、致病的或未知的化學物質和生物，實驗室應通風良好。為了防止吸收一些蒸汽、氣體和顆粒，必須通過通風柜、通風櫥或局部通風除去污染物。

　　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.

　　潔凈工作臺(超凈平臺)是為保護實驗產品或產品而設計的。垂直或水平的層流空氣吹過工作區域，可以防止測試產品或產品被工作區域外的灰塵或細菌污染，對提高產品成品率、精度、穩定性和可靠性有顯著作用。

　　通風柜的目的是保證實驗的安全，也是排出有害氣體不可缺少的一部分。為了防止實驗室工作人員吸入一些有毒的、致病的或未知的化學物質和生物，實驗室內應有良好的通風。為了防止吸收一些蒸汽、氣體和顆粒，必須通過通風柜、通風櫥或局部通風除去污染物。
