(3) Items cannot be stacked on the purification workbench, and the air inlet should be kept unblocked. (2) The range of motion should not be too large or too intense, so as not to damage the workbench. Matters needing attention: (1) After the ultraviolet lamp is turned off, the fan must be turned on to dissipate the ozone before the experiment can be carried out, otherwise it cannot be carried out. (4) After the work is over, clean the work surface, turn off the fan and lighting switch, and use detergent and disinfectant to clean and disinfect the work table. (3) Before using the workbench, wipe it with an alcohol solution with an alcohol concentration of 75% for disinfection. (2) Unnecessary items cannot be stored in the purification work area to ensure the smooth and normal flow of airflow. After 30 minutes, turn off the UV lamp and start the fan. Operation method: (1) Before use, turn on the machine 50 minutes in advance, and then turn on the UV lamp to sterilize. It is also because some chemical and pharmaceutical companies will have some toxic and harmful gases during the experimental operation that will affect human health, so it seems more appropriate to choose the vertical laminar flow that blows downward instead of the water laminar flow. The difference in the place of use: horizontal flow is currently mainly used for food inspection, inoculation and tissue culture of flowers, saplings, and edible fungi vertical laminar flow is used in electronics, chemicals, hospitals, and pharmaceutical industries. When the vertical ultra-clean workbench is not in use, the baffle can be lowered and closed. Differentiation of sealing performance: the horizontal workbench is open, and the vertical ultra-clean workbench has a lifting glass baffle or plexiglass baffle in front of it. Distinguished by price: From the perspective of the complexity of materials and workmanship, the vertical ultra-clean workbench is more complicated, requires more materials and labor, and the price is slightly more expensive than the horizontal one, but the correlation is not great. If it can’t reach the ultra-clean table with 100-level purification, it is a defective product. All of them meet the 209E level 100 purification of the US federal standard. Distinction of cleanliness: the efficiency of horizontal ultra-clean benches and vertical ultra-clean benches is exactly the same, and there is no difference in cleanliness. To make a simple analogy, the ultra-clean table with horizontal laminar flow is like a desk fan placed on the table, and the clean bench with vertical laminar flow is like a ceiling fan hanging from the ceiling. The wind direction of the vertical ultra-clean table is vertical laminar flow, and the wind blows from top to bottom. Distinction of working principle: the working principle of the horizontal ultra-clean table and the vertical ultra-clean table are exactly the same, the difference is only the appearance from the literal meaning, the wind of the horizontal ultra-clean table is horizontal and flat. Each product is tested one by one in strict accordance with the US Federal 209E standard before leaving the factory, with quality assurance and high reliability. Light touch operation panel, step less speed regulation, easy operation 4. After testing, under the condition of the initial resistance of the high-efficiency filter, it can save energy by more than 50%, effectively reducing the operating cost 3. Adopt a direct-drive high-efficiency centrifugal fan, low noise, long life, and maintenance-free 2. The laminar airflow cabinet is divided into horizontal laminar airflow and vertical laminar flow hood.įeatures: 1. It is designed to protect both the operator and the sample from contamination by providing a constant flow of filtered air. This airflow creates a barrier between the work being done inside the hood and the outside environment.Ī laminar flow cabinet is a type of laboratory equipment that is used to provide a sterile working environment for various laboratory procedures. The laminar flow hood works by creating a constant flow of filtered air that moves in a uniform direction, from the top of the hood down to the work surface. Widely used in various industries and scientific research departments such as medical and health care, pharmaceuticals, tissue culture, laboratories, electronics, and precision instruments. It uses air-cleaning technology to make the space in a certain operating area reach a corresponding dust-free and sterile state. The laminar air flow chamber is a kind of local purification equipment that provides a dust-free working environment.
