三级生物安全柜
Class III cabinets are leak-tight, totally enclosed but ventilated cabinets, where all air that either enters or leaves through the facility pass through a HEPA filter.
The cabinets are provided with rubber gloves that are attached to the system to be used during operations in the cabinet. This is why these cabinets are also termed ‘glove boxes’.
The cabinet even has a transfer chamber that facilitates the sterilization of materials before they leave the glove box.
Even though the gloves restrict the hand movement of the operator inside the cabinet, it prevents direct contact between the operator and the samples.
The exhaust air is treated with double HEPA filters or HEPA filters in combination with incineration.
These cabinets can be used for all four Biosafety levels (1, 2, 3, and 4). But these are the most important for the manipulation of biological materials in the Biosafety level 4.
These cabinets are mostly custom-built for specific laboratories with lab equipment built inside the chamber.
All of these structural and design features provide maximum protection to the operator, the environment, and the sample against the high-risk group 4 pathogenic organisms.

一级生物安全柜
一级生物安全柜保护操作人员和环境免受生物危害的暴露。它不能防止在机柜中处理的样品接触到可能存在于室内空气中的污染物。
二级生物安全柜
二级生物安全柜同一级生物安全柜一样,气体也是从外部流入二级生物安全柜,通常称为进流。进流能够防止微生物操作时产生的气溶胶从安全柜前面操作窗口逃逸到实验室内。
三级生物安全柜
III级机柜是漏气密封、完全封闭但通风的机柜,所有进入或离开设备的空气都要通过高效空气过滤器。
