The advantages of the ultra-clean workbench are that the operation is convenient and comfortable, the work efficiency is high, the preparation time is short, and it can be operated for more than 30 minutes after starting up, and it can basically be used at any time. In factory production, the inoculation workload is very large, and the clean bench is an ideal equipment when it needs to work for a long time. The ultra-clean workbench is powered by a three-phase motor with a power of about 145-260W. The air is blown out through a "super filter" composed of a special micro-cellular foam sheet laminated to form a continuous dust-free Sterile ultra-clean air laminar flow, the so-called "high-efficiency special air", removes dust, fungi and bacterial spores larger than 0.3μm, etc. 
The flow rate of ultra-clean air is 24~30m/min, which is enough to prevent pollution caused by possible disturbance of nearby air, and this flow rate will not prevent the use of alcohol lamps or Bunsen burners to burn and disinfect instruments. The staff operates under such sterile conditions to keep sterile materials free from contamination during the transfer inoculation process. But in the event of a power outage in the middle of an operation, materials exposed to unfiltered air are not immune to contamination. At this time, the work should be terminated quickly, and a mark should be made on the bottle. If the material in the bottle is in the proliferation stage, it will not be used for proliferation in the future and will be transferred to rooting culture. If it is a general production material, it can also be discarded because it is extremely abundant. If it is in the rooting process, it can be reserved for later planting.
Before using the ultra-clean workbench, apply UV light for 30-40 minutes, and check that various openable doors and windows around the operating area are in their working positions. The operation is carried out in the center of the operation area, which is a safer area by design. Before operating, you should have a preliminary understanding of the experimental materials, and at the same time understand the performance and safety level of the equipment you use. Strictly enforce laboratory safety procedures. The use of specific pathogens in any clean bench must be assessed for safety. If the experimental material will cause environmental pollution to the surrounding environment, it should be avoided in the model without exhaust filter plate, because operation in flowing air is no different from poisoning. Any advanced equipment cannot guarantee the success of the experiment. The use of the ultra-clean workbench in the animal quarantine laboratory is for the purpose of sterility and avoiding cross-contamination, so skilled operation and clear aseptic essentials are essential.
The ultra-clean workbench is a relatively precise electrical equipment, and it is very important to carry out regular maintenance and maintenance on it. First of all, it is necessary to keep the room dry and clean. The humid air will not only corrode the manufacturing materials, but also affect the normal operation of the electrical circuit. The humid air is also conducive to the growth of bacteria and mold. A clean environment also extends the life of the filter plates. In addition, regular cleaning of equipment is an important part of normal use. Cleaning should include routine cleaning before and after use and regular disposal. During fumigation, all gaps should be completely sealed. For example, the operation port is equipped with a type of ultra-clean workbench with a movable baffle cover, which can be sealed with plastic film. The filter plate and ultraviolet germicidal lamp of the ultra-clean workbench have a calibrated service life and should be replaced on schedule.
