Ultra-clean bench power adopts two-phase three-wire system, in which there is one zero line, which connects the machine housing and should be connected to the ground. The other two lines are phase lines and the working voltage is 220V.
The inlet of the super-clean bench is at the bottom of the back or front. There is an ordinary foam sheet or non-woven fabric inside the metal mesh cover to block large particles of dust. It should be inspected, removed and washed frequently. If the foam is found to be aging, it must be replaced promptly. In addition to the air inlet, if there is air leak, it should be blocked, such as adhesive plaster, plug cotton, paste glue paper and so on. The metal mesh cover on the front of the worktable is an ultra filter. The super filter can also be replaced. If the filter is used for a long time, the dust particles will be blocked and the wind speed will be reduced. If aseptic operation cannot be guaranteed, it may be replaced with a new one.
The length of life of a clean bench is related to the cleanliness of the air. Ultra-clean benches can be used in general laboratories in temperate regions. However, in tropical or sub-tropical regions, due to high levels of pollen or dusty areas in the atmosphere, super-clean benches should be placed in better indoor rooms with double doors. use. In any case, the inlet hood of the clean bench should not be facing the open door or window, so as not to affect the service life of the filter.
The sterile room should be regularly dusted and disinfected with 70% alcohol or 0.5% phenol spray, and wiped with 2% benzalkonium chloride. Table tops and utensils 70% alcohol can also be regularly sealed with formalin 40% formaldehyde plus a small amount of potassium permanganate Fumigation, with the UV sterilization lamp turned on more than 15 minutes each time disinfection and sterilization methods, so that the sterile room often maintain a high degree of sterility. The inside of the inoculation box should also be equipped with a UV lamp. Before use, the lamp should be turned on and sterilized by irradiation for more than 15 minutes. However, if there is no radiation, it can be sterilized. When the UV lamp is turned on for a long time, oxygen molecules in the air can be excited to associate with ozone molecules. This gas component has a strong bactericidal effect and can sterilize the corners where the ultraviolet rays do not directly reach. Because ozone is unhealthy, turn off the UV lamp before entering the operation and allow it to enter for more than 10 minutes.
Ultraviolet lamps can also be mounted on clean benches, but they should be mounted outside the lampshade and staggered with the lamps arranged in parallel so that they do not interfere with lighting during operation. If an ultraviolet lamp is installed in a lampshade or glass plate, this is useless because ultraviolet rays cannot penetrate the glass. Its lamp tube is quartz glass, not silicate glass.
