Now the country attaches great importance to the safety of drugs and food, and people begin to care about their own safety. For example, relevant departments require that the results of pathological studies be reliable, and even animals used for detection must be raised and reproduced in a clean environment. In order to ensure the accuracy of the experimental results, it is also a protection of the laboratory environment, to keep employees away from possible infections, such as laboratory purification, experts say, from the point of view of microbial safety control is very high, to meet the requirements of laboratory purification biology laboratory, can be divided into the following four grades.
四级实验室 技术实现 指标:
Level IV Laboratory Technical Indicators:
There is no requirement of grade 1 cleanliness. Minimum ventilation frequency, window opening frequency, minimum negative pressure difference between adjacent outdoor rooms, temperature 18-28 C, relative humidity < 78百分比, noise < 60 dB, minimum illumination 200;
There is no requirement of level 2 cleanliness. Minimum ventilation frequency, window opening frequency, minimum negative pressure difference between adjacent outdoor rooms, temperature 18-27 C, relative humidity 30-60百分比, noise < 60 dB, minimum illumination 300;
三级洁净度:7级或8级;低通风:15或12;小负压差:-10为与相邻客厅相连的露天客厅;温度:℃年龄在18岁至25岁之间;相对湿度:30 - 60百分比;噪音≤60分贝;低照度:350;
Level 3 cleanliness: Level 7 or 8; Minimum ventilation: 15 or 12; Minimum negative pressure difference: - 10 is an outdoor room connected with adjacent rooms; Temperature: - 18 to 25 years old; Relative humidity: 30 - 60百分比; Noise < 60 decibels; Minimum illumination: 350;
Level 4 cleanliness: 7 or 8, minimum ventilation times: 15 or 12, minimum negative pressure difference of adjacent outdoor rooms: -10, temperature: 18-24 C, relative humidity: 30-60百分比, noise < 60 dB, minimum illumination: 350.
The above four types are the division of laboratory purification grade, I hope it will be helpful to you.
