Ultra clean worktable is a one-way flow type air purification equipment that provides a local dust-free and sterile working environment. It is widely applicable to the scientific research and production departments that need local clean and sterile working environment, such as medicine and health, biopharmaceuticals, food, medical science experiments, optics, electronics, aseptic room experiments, aseptic microbial testing, plant tissue culture and inoculation. It can also be connected into an assembly line with the advantages of low noise, mobility, etc. It is a kind of air purification equipment with strong universality to provide local high cleanliness working environment. Its use has good effects on improving process conditions, improving product quality and increasing yield.
Note: The clean bench is different from the biosafety cabinet.
The ultra clean worktable can only protect the reagents operated in the worktable from pollution, and does not protect workers. The biosafety cabinet is a negative pressure system, which can effectively protect workers.
Its working principle is that the air is sucked into the prefilter by the fan, filtered by the high efficiency filter through the static pressure box, and the filtered air is sent out in the form of vertical or horizontal airflow, so that the operating area can reach the 100 level cleanliness and ensure the production requirements for environmental cleanliness. The ultra clean worktable can be divided into vertical flow ultra clean worktable and horizontal flow ultra clean worktable according to the direction of air flow. It can be divided into unilateral operation and bilateral operation according to the operation structure. It can also be divided into ordinary ultra clean worktable and biological (medical) ultra clean worktable according to its use.
The principle of ultra clean worktable is that in a specific space, the indoor air is initially filtered by a pre filter, pressed into the static pressure box by a small centrifugal fan, and then filtered by an air HEPA filter. The clean air flow from the air outlet of the air HEPA filter has a certain and uniform cross section wind speed, which can eliminate the original air in the work area and take away the dust particles and biological particles, so as to form a sterile and highly clean working environment.
From the airflow direction, it can be divided into: vertical flow ultra clean workbench and horizontal flow ultra clean workbench; The ultra clean worktable is divided into single worktable and double worktable according to the number of operators; The ultra clean worktable is divided into conventional type, new type push-pull type and self circulating loop type (only for vertical DC) in structure.
The ultra clean worktable is divided into vertical flow ultra clean worktable and horizontal flow ultra clean worktable according to the direction of air flow. The vertical flow worktable is noisy because the fan is on the top, but the vertical wind is mostly used in medical engineering to ensure human health; The horizontal flow worktable has less noise than the wind, so it is mostly used in the electronics industry, and has little impact on health. According to the operation structure, it can be divided into unilateral operation and bilateral operation. According to its use, it can also be divided into ordinary ultra clean workbench and biological (medical) ultra clean workbench.
