The purpose and usage method of the hundred level laminar flow cabinet

Usage of Class 100 laminar flow cabinet:
A hundred level purification workbench is a laminar flow device that is a closed operating table or cabinet with filtered clean air, usually used as part of a clean laboratory. In recent years, ultra clean workbenches have been widely used in operating environments that require clean air, such as biomedical research, pharmaceuticals, and space science.     

By filtering through the filter, the ultra clean workbench can effectively eliminate suspended particles, bacteria, and mold contamination in the air, making the results of inspection operations more reliable and providing better clinical results.    
Instructions for using a hundred level purification workbench:
1. Connect the power supply
2. Turn on the fan 20 minutes in advance.     
3. Start the indoor ultraviolet lamp sterilization 30 minutes in advance.
Precautions for using a hundred level purification workbench:
1. Before using newly installed or long-term unused ultra clean workbenches, the Class 100 purification workbenches and surrounding environment must be cleaned with ultra clean vacuum cleaners or fiber free tools.     
2. It is forbidden to record on the workbench. During work, it is necessary to avoid making obvious movements that disturb the airflow as much as possible.    
3. Do not store unnecessary items on the level 100 purification workbench to maintain the normal flow of clean air in the work area without interference.   
Advantages and structure of a hundred level purification workbench:
The advantages of the purification operation platform are easy and comfortable operation, high operating efficiency, short preparation time, and can be operated in more than 10 minutes after startup. It can be used at any time. In factory production, when the inoculation operation volume is large and requires frequent and long-term operation, the purification table is an ideal equipment. The purification table 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 specially made microporous foam plastic sheets laminated together to form a continuous, dust-free and sterile laminar flow of purified air, the so-called "special air", which removes dust, fungi, bacterial spores, etc. larger than 0.3 μ m. The flow rate for purifying the air is 24-30m/min, which is sufficient to prevent pollution caused by possible air disturbance nearby. Such a flow rate will not hinder the use of alcohol lamps or Bunsen lamps for burning and disinfecting equipment. The operators operate under such sterile conditions, ensuring that the sterile materials are not contaminated during the transfer and inoculation process. But if there is a power outage during operation, the materials exposed to unfiltered air will be difficult to avoid contamination. At this point, the operation should be quickly terminated and marked on the bottle. If the material inside is in the proliferation stage, it will no longer be used for proliferation and will be transferred to rooting culture in the future. If it is a general production material, it can also be discarded due to its extreme abundance. If it is in the process of rooting, it can be left for future planting.
The power supply for the purification workbench often adopts a three-phase four wire system, with one neutral wire connected to the machine casing and firmly connected to the ground wire. The other three wires are all phase wires, and the operating voltage is 220V. There is a certain order in which the three wires are connected to the circuit. If the wire end is connected incorrectly, the fan will reverse, and the sound will be normal or slightly abnormal. There is no wind on the front of the purification workbench (you can observe the movement with an alcohol lamp flame, and it is not advisable to test for a long time). The power supply should be cut off in a timely manner. Just swap the wire ends of any two phases and connect them again to solve the problem. If only two phases are connected to the three-phase line, or if one phase of the three-phase line has poor contact, the machine sound is very abnormal. The power should be cut off immediately and carefully inspected, otherwise the motor will be burned.
