　　Myth 1: The automatic cleaning machine is simple to operate, and the operators do not need special training.

　　With the continuous development of automatic control technology and programming technology, the control system of automatic cleaning machine is becoming more and more intelligent, and the human-computer interface is becoming more and more friendly.

　　The operation of the automatic cleaning machine becomes simple. Sometimes it is only necessary to press the power switch to complete a complete set of cleaning tasks from pre cleaning to drying. in truth. However, after all, the automatic cleaning machine is a complex electrical equipment. How to use, maintain and maintain it requires special training to ensure the safety of equipment and operators. Most automatic cleaning machines are equipped with programming function, which can set different cleaning and flushing procedures and adjust parameters such as cleaning temperature and cleaning time according to the cleaning object and residue type.

　　If operators receive special training, they can continuously optimize the process conditions by tracking and recording all cleaning parameters according to their actual conditions, so as to improve cleaning efficiency, reduce the consumption of cleaning agent and reduce energy consumption.

　　Myth 2: Automatic bottle washing machine is a powerful device, so any glassware can be washed.

　　Because the automatic washing machine can clean large quantities of glassware of the same/similar specifications one time, for example, the large automatic bottle washing machine can clean 300 or more Petri dishes, more than 1000 test tubes, or dozens of volumetric flasks. Considering that the glassware in the laboratory has different structures, sizes and capacities, if the glassware can be properly classified and equipped with appropriate device supports, the powerful cleaning ability of the automatic cleaning machine can be maximized. For some vessels or parts with complex or small shapes, other cleaning methods, such as ultrasonic, may be more efficient and effective. If the residues contain proteins that will coagulate when heated, special care should be taken when using the automatic cleaning machine. The proteins should be cleaned at room temperature, and then heated for cleaning. However, it is still possible for proteins to adhere to the inner surface of equipment or device surface after solidification, which is very troublesome to clean. Similarly, there are very adhesive polymers. In this case, appropriate pre-treatment may be necessary. In addition, limited by the scope of application of cleaning equipment and water-based cleaning agents, some water-based cleaning agents cannot wet the insoluble residues that penetrate or dissolve, such as the complex insoluble residues that remain when strong oxidizing acids are used to digest samples at high temperatures in some tests, and cannot be cleaned by automatic cleaning machines.

　　Mistake 3: The automatic cleaning machine has strong cleaning ability, with pressure, spraying and circulation. It can prepare cleaning solution at will without using special cleaning agent.

　　The well-designed automatic cleaning machine has a powerful circulating pump and well-designed nozzle, which can spray the cleaning solution evenly and continuously to the device surface to remove residues. A lot of residues can be cleaned by heat, the solubility of water itself to residues and jet pressure. However, due to the large surface tension of water, the cleaning ability of pure water is limited for some small particles and organic substances that are difficult to dissolve in water. Due to the circulation and spraying of the automatic cleaning machine, ordinary cleaning agents contain surfactants, which will form a large number of foam. On the one hand, these foam will overflow, on the other hand, it may also cause damage to the circulating pump, so the automatic cleaner can only use cleaning agents without foam or low foam.

　　The special cleaning agent contains not only alkali or acid, but also various active substances such as chelating agent and complexing agent. Through the synergistic action of these active substances, the residues can be better dissolved and dispersed. In addition, the cleaning solution should not only have the cleaning ability to remove residues, but also not damage the surface and pipeline of the equipment. When the equipment manufacturer recommends the cleaning agent, it can only be used after careful testing and evaluation to confirm that all conditions are met.

　　Self prepared equipment is easy to be damaged due to ignorance of the material characteristics of the equipment. The selection of stable and high-quality special cleaning agent can not only maximize the potential of the equipment, extend the service life of the equipment, but also ensure the stability and repeatability of the cleaning process to the greatest extent.

　　Myth 4: The automatic cleaning machine is made of stainless steel, which is sturdy and durable, without regular maintenance.

　　Due to frequent contact with acid and alkali, the automatic cleaning machine needs to have a good resistance to various chemicals. It is usually made of high-performance stainless steel materials.

　　Nevertheless, it is still necessary to maintain the equipment regularly. It can ensure that the equipment is available at any time and prolong the service life of the equipment.

　　This is because some frequently rotating parts, such as peristaltic pump and its hose, circulating pump, etc., need regular inspection and replacement of accessories to ensure that the detergent can be inhaled normally according to the set value and the equipment can operate normally. Long term shutdown may also lead to failure of some valves or blockage of pipes by impurities. Such maintenance can be completed by internal equipment engineers or outsourced to equipment manufacturers.

　　Regular maintenance of the automatic cleaning machine is conducive to long-term, efficient use of the equipment and maximum value of the equipment.
