Light: Special structure: Sufficient light is required to observe the small colonies cultured in capsules, flagella, and pili, as well as the agglutinating particles in serum tests. According to the specific requirements of experimental equipment, the power distribution engineering of the clean laboratory is designed by professional designers, which is very different from ordinary buildings. Because the circuit requirements of laboratory instruments and equipment are relatively complex, not as people usually think, as long as they meet the requirements of voltage and power. In addition to conventional lighting, the surgical area also requires the installation of a surgical table lamp to ensure correct judgment of experimental results.

通风:由于各种致病菌和污浊空气的集中，实验室要求保持在一排生物安全柜内。疾控中心实验室仪器布局设计是实验室设计的和难点之一。实验仪器的布置看似简单，其实要考虑的因素很多。实验室仪器是否能安全、良好地运行，是否能得到妥善的保护，是否能减少环境的影响，是否相互影响，实验室人员是否能方便地使用等等，都是在考虑实验室仪器放置时需要注意的问题。

Ventilation: Due to the concentration of various pathogenic bacteria and polluted air, the laboratory requires to be kept in a row of biosafety cabinets. The layout design of laboratory instruments in the Center for Disease Control and Prevention is one of the key and difficult points in laboratory design. The arrangement of experimental instruments may seem simple, but there are actually many factors to consider. Whether laboratory instruments can operate safely and well, whether they are properly protected, whether they can reduce environmental impact, whether they interact with each other, whether laboratory personnel can use them conveniently, and so on, are all issues that need to be considered when placing laboratory instruments.

温度和湿度:由于无菌操作的要求，实验过程中经常使用酒精灯，所以微生物实验室不能安装吊扇。为了达到适合实验的温度，特别是满足一些仪器的温度和湿度要求，实验室应配备空调。

Temperature and humidity: Due to the requirements of sterile operation, alcohol lamps are often used during the experiment, so ceiling fans cannot be installed in the microbiology laboratory. In order to achieve a suitable temperature for the experiment, especially to meet the temperature and humidity requirements of some instruments, the laboratory should be equipped with air conditioning.

电源:要求提供电压稳定、频率恒定的电源；根据仪器设备的要求，必要时应提供不间断电源。

Power supply: It is required to provide a stable voltage and constant frequency power supply; According to the requirements of the instrument equipment, an uninterrupted power supply should be provided when necessary.

水源:水源应设置在洁净实验室作业区。用于标本处理的水槽不应与工作人员洗手的水槽混合使用。

Water source: The water source should be located in the clean laboratory operation area. The sink used for specimen processing should not be mixed with the sink where staff wash their hands.
