分钟以上即可操作，基本上可随时使用。 The advantages of ultra-clean bench are easy to operate, relatively comfortable, high work efficiency, short preparation time, can be operated for more than 10 minutes, and it can basically be used at any time. ～ 260W左右，将空气通过由特制的微孔泡沫塑料片层叠合组成的“超级滤清器”后吹送出来，形成连续不断的无尘无菌的超净空气层流，即所谓“高效的特殊空气”，它除去了大于0.3 μ m的尘埃、真菌和细菌孢子等等。 The ultra-clean workbench is powered by a three-phase motor, with a power of about 145 to 260W . The air is blown out after passing through a "super filter" composed of a special micro-cellular foam plastic sheet laminated, forming a continuous dust-free. Sterile ultra-clean air laminar flow, the so-called "efficient special air", removes dust, fungi, bacterial spores, etc. that are larger than 0.3 μm. ～ 30m/min ，这已足够防止附近空气可能袭扰而引起的污染，这样的流速也不会妨碍采用酒精灯或本生灯对器械等的灼烧消毒。 The flow rate of ultra-clean air is 24 to 30m / min , which is enough to prevent possible pollution caused by nearby air. This flow rate will not prevent the use of alcohol lamps or Bunsen burners to burn and disinfect instruments. Workers operate under such aseptic conditions to keep sterile materials free from contamination during transfer vaccination.
The air inlet of the ultra-clean workbench is under the back or front. There is an ordinary foam plastic sheet or non-woven fabric in the metal mesh cover to block large particles of dust. It should be inspected, disassembled and washed frequently. If the foam is found to be aging, it should be replaced in time. Except for the air inlet, if there are air leakage pores, they should be closed tightly, such as sticking tape, stuffing cotton, sticking glue paper, etc. Inside the metal mesh cover on the front of the workbench is a super filter, which can also be replaced. If the dust particles are clogged and the wind speed is reduced due to long-term use, you can replace it with a new one.
The service life of the clean bench is related to the cleanliness of the air. Ultra-clean benches can be used in general laboratories in temperate regions, but in tropical or subtropical regions, due to the high amount of pollen or dusty areas in the atmosphere, ultra-clean benches should be placed in better indoor rooms with two doors. use. Under no circumstances should the air inlet hood of the clean bench be facing the open door or window, so as not to affect the service life of the filter.
酒精或0.5%苯酚喷雾降尘和消毒，用2%新洁尔灭抹拭台面和用具（70%酒精也可） ，用福尔马林（40%甲醛）加少量高锰酸钾定期密闭熏蒸，配合紫外线灭菌灯（每次开启15分钟以上）等等消毒灭菌手段，以使无菌室经常保持高度的无菌状态。 The sterile room should be regularly dusted and disinfected with 70% alcohol or 0.5% phenol spray, wipe the countertops and utensils with 2% Xinjieer (70% alcohol is also acceptable ) , and use formalin (40% formaldehyde ) plus a small amount of permanganic acid. Potassium is regularly sealed and fumigated, and disinfection and sterilization methods such as ultraviolet sterilization lamps ( more than 15 minutes each time ) are used to keep the sterile room always highly sterile. 分钟以上照射灭菌，但凡是照射不到之处仍是有菌的。 The inside of the inoculation box should also be equipped with an ultraviolet lamp, and the lamp should be sterilized by irradiation for more than 15 minutes before use. However, there is still bacteria in the place where it is not exposed. When the UV lamp is turned on for a long time, it can excite oxygen molecules in the air to associate with ozone molecules. This gas component has a strong sterilizing effect and can produce a sterilizing effect on the corners that are not directly exposed to ultraviolet rays. Because ozone is harmful to your health, you should turn off the ultraviolet light before entering the operation, and you can enter it more than ten minutes after turning off.
