What is the difference between a laboratory and a clean room
What is the difference between a laboratory and a clean roomI. Different needs for a clean environmentClean laboratory and clean room the specific needs of a clean environment is different. Laboratory decoration includes a wide range of general laboratories and clean laboratories. Clean laboratories and clean rooms are on the cleanliness of certain requirements, according to the removal of the number of particles contained in the air, are divided into different levels, that is, cleanliness However, some specific clean laboratories such as testing laboratories, and biological laboratories in addition to the cleanliness requirements are more concerned about the organization of the airflow, that is, the direction of airflow, which is to ensure that the samples and personnel will not be contaminated with harm. II. What are the requirements of a clean laboratory Laboratories often use a clean environment, generally based on different types of laboratories, the core of the control is different. The first is to achieve the later production and investment in research and development laboratories, such as drug development, electronics research, and development, etc. The core of control is the same as a clean room, it is all about controlling microorganisms or particulate matter. Another large category of labs that use clean environments is biological labs, especially biosafety labs. These labs don't require much in the way of a clean environment per se. Although they are all microbiological experiments, they are usually for certain samples and airborne microorganisms have little effect. Of course the better the environmental conditions the more favorable they are, and they pay more attention to the airflow organization in the room. Preventing dangerous samples from diffusing outward to affect the outside world during operation, as opposed to sample contamination, preventing diffusion is the main point of control. For this type of laboratory, a reasonable arrangement of the room air supply and exhaust vents, a reasonable choice of air outlets, and a reasonable arrangement of the equipment in the room and the operating area, through these operations, ensure that the indoor air is always flowing from the clean area to the contaminated area, the airflow will not destroy the airflow distribution of the operating area, which is the core point of the entire design. III. What are the requirements for the clean room According to the different types of clean rooms, the control parameters in the air will be different, such as electronic rooms, the main control of the impact of particles, as well as pharmaceuticals, food, operating theatres, and so on. All prevent the influence of microorganisms. Because microorganisms are attached to the particles, removing the particles gets rid of the microorganisms. The general size of microorganisms is also micron level, so for the control of microorganisms, the level of clean environment requirements will not be particularly high. Compared to the control of the electronic room, the electronic room generally needs to control to the nanometer level, the required environmental requirements will be higher, while the control of microorganisms generally only needs to the micron level. Both microorganisms and particles are controlled through the principles of cleanliness, i.e. dilution and extrusion, to achieve the control requirements of their indicators. |
