Before purchasing an imported autoclave, you first need to know that imported autoclaves, especially imported autoclaves of 50 liters or more, are special equipment in China. Before use, users need to check with local special equipment. The institution (or the inspection office or the technical supervision bureau, according to the actual situation of each place) handles the use permit. The certificates that need to be submitted when applying for a license to use include:
1. "Import Pressure Vessel Production License", referred to as pressure vessel license. This certificate is applied to the China Quality and Technical Supervision Bureau by the manufacturer of the pressure vessel. Each instrument will be randomly brought with a pressure vessel production license of the same fuselage number;
2. "Import and Export Boiler and Pressure Vessel Safety Performance Inspection Certificate", this certificate shall be declared by the importer at the time of customs import, and the customs shall notify the relevant special equipment testing institutions to carry out import declaration inspection. In some areas, the user may also The goods will be applied to the local special equipment testing agency within 30 days. This certificate is a charge item.
Third, the user needs to remove the pressure gauge and pressure reducing valve on the autoclave, and send it to the local measurement department to obtain the measurement certificate.
The three certificates are available to obtain the pressure vessel use permit in compliance with the law and to be regularly inspected by the local technical supervision bureau. If there is no license, the autoclave is a black household, and it is illegal to use an unlicensed autoclave.
It can be seen that the domestically produced autoclave has no "Import Pressure Vessel Production License" and "Import and Export Boiler Pressure Vessel Safety Performance Inspection Certificate", which can distinguish which products are imported autoclaves, which The product is actually the domestically produced or domestically assembled product under the banner of the original imported autoclave.
Second, consider the safety performance of the autoclave. The principle of the autoclave (autoclave) is basically the same as that of the autoclave. Therefore, safety must first consider explosion protection. Advanced imported autoclave usually relies on a temperature sensor to control the temperature, and has a pressure sensor. When the temperature or pressure is abnormal, the power is automatically cut off to ensure safety. Compared with the pressure gauge, the internal pressure is not required. Control, security is higher.
More advanced configuration, such as the CLG series autoclave produced by ALP Japan, has built-in dual temperature and pressure sensors, which can automatically sense the relationship between temperature and pressure, ensuring that there will be no abnormal pressure and safety. . Imported autoclave, such as the CL series autoclave of ALP Company of Japan, adopts mechanical lock and electronic lock double lock device. If the lock fails or the cover is not covered, the instrument will not start; after sterilization is completed, the instrument It needs to be lowered to below 80 degrees and normal pressure, and the electronic lock can be opened to prevent accidental burns. At the same time, a good imported autoclave does not directly expose the stainless steel on the inner surface of the metal cavity, but has an insulating coating to prevent electric leakage and injury. Other safety features, such as water shortage protection against dry burn, electrode fault indication, abnormal time indication, etc. A detailed look at the safety performance of your instrument prior to purchase can help you understand the performance of your instrument.
The third point is to understand the performance of the instrument. Usually imported autoclaves can automatically complete the heating - exhaust - valve closure - sterilization - exhaust. The fully-automated imported autoclave also provides a separate melting-heating procedure. This single procedure is ideal for laboratories that require hygienic testing for the melting of media. Low-end, economical sterilizers usually do not have this feature.
Then, depending on the needs of the actual application, you need to determine if additional features are needed. For example, data printing is a basic requirement of the current GLP lab. Don't forget to choose a printer or data logger for your autoclave. If you need rapid cooling of the sample or a large amount of sterilization, you need to save the sterilization time, you can choose an autoclave with a cooling fan. If it is used for sterilization of clothing, if you want to dry the sample or clothing directly after sterilization, you can choose an autoclave with warm air drying. If the actual temperature requirements in the sterilization chamber are strict, you can choose to add a temperature probe to ensure that the sterilization is completely under the set conditions, especially for the treatment of samples with poor thermal conductivity.
Finally, it is also important to note that if you are using an autoclave in a sanitation or biochemical laboratory, you will be required to perform aseptic discharge. Please choose an autoclave with an air filter. If it is used for sterilization of clean space protective clothing, because the air between the clothes is difficult to discharge the autoclave during the heating process, the presence of a large amount of air may cause an explosion hazard due to abnormal pressure. It is best to equip with a high pressure with pre-vacuum function. Sterilizer. However, there are very few autoclaves that can be equipped with air filtration or pre-vacuum. According to the survey, only the CLG series produced by ALP in Japan currently sells in China.
Of course, in addition to the above certificates and functional factors, it is also very important to choose the right supplier. It is generally best to find an agent for the product, which can guarantee the best price, fast delivery and excellent service. Take the imported Japanese ALP autoclave as an example, the product is exclusively represented by Southeast Science and Technology Company. Headquartered in Guangzhou, Southeast Science and Technology has branches in Beijing, Shanghai, Hangzhou, Chengdu, Xi'an and Shenzhen, which can provide product sales and technical support. It is of course reassuring that such special instruments are found by companies that are officially authorized by the factory.
