The advantage of the ultra-clean platform is that it is easy to operate, comfortable, high 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 vaccination workload is very large, and when it is necessary to work for a long time, the ultra-clean platform is an ideal equipment. The ultra-clean platform is driven by a three-phase motor with a power of 145-260W. The air is blown out through a “super filter†consisting of a special micro-porous foam sheet, which forms a continuous dust-free. The ultra-clean air laminar flow of bacteria, the so-called "high-efficiency special air", removes dust, fungi and bacterial spores larger than 0.3 μm. The flow rate of the clean air is 24 to 30 m/min, which is enough to prevent the pollution caused by the nearby air, and the flow rate does not hinder the burning and disinfection of the device by the alcohol lamp or the Bunsen burner. The staff is operated under such sterile conditions to keep the sterile material uncontaminated during the transfer inoculation process. However, in the event of a power outage in the middle of the operation, materials exposed to unfiltered air will not be immune to contamination. At this time, the work should be completed quickly, and the bottle should be marked. If the material inside is in the stage of proliferation, it will not be used for proliferation and then transferred to rooting culture. If it is a general production material, it can be discarded because it is extremely rich. If it is in the rooting process, it can be left for later planting.
The ultra-clean power supply adopts three-phase four-wire system, 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). To cut off the power supply in time, just replace the wire ends of any two of them and connect them to solve the problem. 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, exempting accidents and losses that should not be caused.
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 found to be aging, it should be replaced 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 when the aseptic operation cannot be guaranteed, it can be replaced with a new one.
The length of service life of the clean bench is related to the cleanliness of the air. In the temperate zone, the ultra-clean bench can be used in general laboratories. However, in tropical or subtropical regions, due to the high level of pollen or dusty areas in the atmosphere, the ultra-clean bench should be placed in a good indoor room with double doors. use. Under no circumstances should the inlet hood of the clean bench be placed against an open door or window to avoid affecting the 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 permanganic acid. Potassium is periodically sealed and fumigation, combined with UV sterilization lamps (opening for more than 15 minutes each time), etc., so that the sterile room is always kept highly sterilized. 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 ultraviolet lamp is turned on for a long time, it can excite oxygen molecules in the air to form ozone molecules. This gas component has a strong bactericidal effect and can sterilize the corners where the ultraviolet rays are not directly irradiated. Since ozone is harmful to health, the UV lamp should be turned off before entering the operation, and it can be inserted after more than ten minutes.
Ultraviolet lamps can also be hoisted on the ultra-clean workbench, but should be placed outside the illuminator and staggered in parallel so that the lighting does not interfere with the work. If the UV lamp is placed inside the lighting cover (glass plate), this is useless because the ultraviolet light cannot penetrate the glass, and its lamp is made of quartz glass instead of silicate glass.
The vaccination room is intended to be simple, and any items that are not directly related to the work of the room can not be placed in order to maintain sterility. The air in the inoculation room should be 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 necessary to clean the 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, as long as the strict aseptic operation procedures are carried out, there is a clean bench in the open room and window, and the pollution rate of the inoculation can still be controlled in production.
