The clean bench is a laminar flow device that is a closed console and cabinet with clean filtered air, usually as part of a cleaning laboratory. Anhui People and Purification pointed out that in recent years, ultra-clean workbench has been widely used in biomedical research, pharmaceutical, space science and other operating environments that require clean air.

Through the filtration of high-efficiency filters, the ultra-clean workbench can effectively eliminate the pollution of suspended particles, bacteria and mold in the air, making the results of the inspection operation more credible and providing better results for the clinic.

Precautions for cleaning the workbench:

1. Newly installed or long-term unused clean benches Before use: Clean the Class 100 clean bench and the surrounding environment with a clean vacuum cleaner or fiber-free tool.

2. It is forbidden to record on the work surface, and work should be avoided as much as possible to avoid the disturbance of airflow.

Purification workbench advantages and structure

The advantages of the purification operation table are that it is convenient and convenient to operate, comfortable, high in operation efficiency, short in preparation time, and can be operated after being turned on for more than 10 minutes, and can be basically used at any time. In factory production, the inoculating operation is very large, and when it is necessary to operate for a long time, the purification station is an ideal device. The clean bench is driven by a three-phase motor with a power of 145-260W. The air is blown out through a “super filter” composed of special microporous foam sheets to form a continuous dust-free sterilizing. The laminar flow of purified air, the so-called "efficient special air", removes dust, fungi and bacterial spores larger than 0.31 m and the like. The flow rate of the purified 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 operator operates 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 operation 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 purifying operation station 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 operating voltage is 380V. There is a certain order in the three-wire access circuit. If the wire head is wrong, the wind is reversed. At this time, the sound is normal or slightly abnormal. The front of the clean bench is windless. (Alcohol light flame can be used to observe the movement and static, it should not be tested for a long time). Turn off the power, 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.
