The advantage of the ultra-clean workbench is that it is easy to operate, comfortable, work efficiency, short preparation time, and can be operated after 10 minutes or more of operation. Basically, it can be used at any time. In factory production, the inoculation work is very large, and when it is necessary to work long hours, the ultra-clean workbench is an ideal equipment. So what problems do you need to pay attention to when using the ultra-clean workbench? Let's analyze it for everyone. Precautions for using the ultra-clean workbench : The ultra-clean power supply adopts three-phase four-wire power, one of which has a zero line, which is connected to the machine casing and should be connected to the ground line. The other three lines are phase lines, and the working voltage is 380V. There is a certain order in the three-wire access circuit. If the wire is connected incorrectly, the wind is reversed. At this time, the sound is normal or slightly abnormal. The front of the clean bench is windless (can be observed with alcohol lamp flame, it should not be tested for a long time). Turn off the power in time, and only connect the wire ends of any two of them to the position and connect them. If the three-phase line is only connected to two phases, or one of the three phases is in poor contact, the machine sound is abnormal. You should immediately cut off the power supply and carefully repair it, otherwise the motor will be burnt. These common senses should be explained to the staff when they start using the ultra-clean platform. The exemption should not cause accidents and losses. The air inlet of the ultra-clean platform is below the back or the front side. There is a common foam sheet or non-woven fabric in the metal mesh cover to block large particles of dust. It should be inspected and removed frequently. If the foam is aging, replace it in time. In addition to the air inlet, if there is a leaking pore, it should be tightly sealed, such as tape, cotton, glued paper, etc. The metal mesh cover on the front of the workbench is a super filter. The super filter can also be replaced. If it is used for a long time, the dust particles are blocked, the wind speed is reduced, and the aseptic [1] operation cannot be guaranteed. of. The length of service life of the clean bench and the cleanliness of the air are available. In the temperate zone, the clean bench can be used in general laboratories. However, in tropical or subtropical regions, in areas with atmospheric pollen or dust, the clean bench should be placed in a good indoor room with double doors. . Under no circumstances should the inlet hood of the clean bench be facing the open door or window to avoid affecting the service life of the filter. The sterile room should be periodically dusted and disinfected with 70% alcohol or 0.5% phenol spray, wiped with 2% chlorhexidine and utensils (70% alcohol is also available), and formalin (40% formaldehyde) plus a small amount of potassium. Regularly closed fumigation, with UV sterilization lamps (opening for more than 15 minutes each time) and other means of sterilization, so that the sterile room is often maintained aseptic. The inside of the inoculation box should also be equipped with an ultraviolet lamp. It should be sterilized by turning on the lamp for more than 15 minutes before use. However, it is still bacteriay where it is not exposed. When the UV lamp is turned on for a long time, the oxygen molecules in the air can be excited to form ozone molecules. This gas has a strong bactericidal effect and can sterilize the corners where the ultraviolet rays are not directly irradiated. Since ozone is harmful to health, you should remove the UV lamp before entering the operation, and you can enter it after more than ten minutes. Ultraviolet lamps can also be hoisted on the ultra-clean workbench, but should be installed outside the illuminator and staggered the arrangement of the illuminators so that they do not interfere with the lighting during operation. If the UV lamp is placed inside the lighting cover (glass plate), it is useless. The ultraviolet light cannot penetrate the glass. Its lamp is quartz glass instead of silicate glass. The vaccination room is intended to be simple, and items that are not directly related to the work of the room cannot be placed in order to maintain sterility. The air in the inoculation room should be absolutely isolated from the outside air, and the reserved ventilation holes should be sealed as much as possible. The venting channel can be provided with upper and lower louvers, and the area of ​​the louver should be slightly larger. It is necessary to cover 4 layers of gauze for simple dust filtering. After a day's work, you can open the window to fully ventilate and then close it. In short, it is clean, dust-free and sterile, and the air is fresh and suitable for work. The gauze covering the ventilation window should be changed frequently. However, the above various measures are only ideal design schemes, and it is often difficult to fully implement them. In fact, only strict aseptic operation procedures are used. In the open windows and doors, there is a clean bench protection, and the pollution rate of inoculation is still controllable in production. level.
