Usage of 100 level purification bench

Purpose of class 100 purification bench: Class 100 purification bench is a laminar flow equipment, a closed operation bench and cabinet with filtered clean air, usually as a part of the cleaning laboratory In recent years, ultra clean bench has been widely used in biomedical research, pharmaceutical, space science and other operating environments that need clean air Through the filtration of the filter, the super clean bench can effectively eliminate the pollution of suspended particles, bacteria and mold in the air, so that the test results are more reliable and provide better results for the clinic Use method of 100 level purification workbench: 1 Connect the power supply; 2 Turn on the fan 20 minutes in advance 3 Turn on the UV lamp for sterilization 30 minutes in advance Precautions for use of class 100 purification bench: 1 Before using the newly installed or long-term unused ultra clean bench, it is necessary to clean the class 100 purification bench and the surrounding environment with ultra clean vacuum cleaner or fiber-free tools 2 It is forbidden to record on the working table, and it is necessary to avoid obviously disturbing the air flow when working 3 Do not store unnecessary articles on the 100 level purification work table in Wuhan air shower room, so as to keep the clean air flow in the work area flowing normally without interference Advantages and structure of 100 level purification working table: the advantages of purification working table are convenient and comfortable operation, high operation efficiency, short preparation time, operation after more than 10 minutes of startup, basically ready for use In the factory production, the inoculation operation is very large, and the purification station is an ideal equipment when it needs to be operated for a long time The cleaning stage is driven by a three-phase motor The power is about 145 to 260W, and the air is blown out through the super filter made of specially made Microcellular Plastic sheets It forms a continuous clean and sterile air purification laminar flow, the so-called "special air" It removes dust, fungi and bacteria spore greater than 0.31 m The flow rate of purified air is 24-30 M / min, which is enough to prevent the pollution caused by the air nearby Such flow rate will not hinder the burning and disinfection of instruments by alcohol lamp or Bunsen lamp Operators operate under such aseptic conditions to keep sterile materials free from contamination during transfer inoculation However, in case of power failure during operation, materials exposed to unfiltered air will not be immune from pollution At this time, the operation should be ended quickly and the 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 be transferred to rooting culture If it is a general production material, it can also be discarded because it is extremely rich If it is in the process of rooting, it can be reserved for later planting The power supply of purification operation platform mostly adopts three-phase four wire system, including one zero wire, which connects the machine shell and should be firmly connected to the ground wire The other three wires are all phase wires, and the operation voltage is 380V There is a certain sequence in the three wire access circuit If the wire head is wrongly connected and the wind opportunity reverses, the sound is normal or slightly abnormal at this time There is no wind on the front of the purification platform (the alcohol lamp flame can be used to observe the movement and static, and it is not suitable to test for a long time) The power supply should be cut off in time As long as the wire head of any two phases is exchanged and connected again, it can be solved If the three-phase line is only connected to two phases, or one of the three phases is in poor contact, the sound of the machine is very abnormal, and the power supply should be cut off immediately for careful maintenance, otherwise the motor will be burned Shangyu Star Instrument Equipment Co., Ltd is located in Daoxu Town, Shangyu District, Shaoxing City, Zhejiang Province It is an enterprise integrating production, product development, processing and trade The company's main products: drying box series, incubator series, laboratory muffle furnace series, distiller series, as well as clean workbench, air shower room, ventilation cabinet, biosafety cabinet and other complete sets of purification equipment The company has a strong technical research and development team, a strong after-sales service system, is the leading manufacturer of complete set of laboratory equipment in China, welcome to buy
