1. The electric centrifuge is a conventional laboratory centrifuge. The instrument has the advantages of large capacity, small temperature rise, low noise, convenient operation, safety and reliability. It is widely used for experimental teaching and research in various fields such as higher education, agricultural science and technology, petrochemical industry, biochemistry, health and epidemic prevention, life science, biological products, pharmaceuticals, and environmental protection. 2. Safety instructions for electric centrifuges: 1. If you find that the power indicator does not light up when starting up, you should stop it for inspection immediately. 2. No-load operation without rotor is strictly prohibited. 3. Check the rotor for corrosion damage before running. 4. Do not open the centrifuge cover when the rotor is running, and do not touch the running rotor. 5. It is strictly forbidden to operate the rotor under unbalanced loading. 3. Instructions for use of electric centrifuge: 1. The working table of the centrifuge should be flat and firm, and the working room should be neat and clean, dry and well ventilated. 2. Open the centrifugal cover and install the test tubes of the same weighing. 3. Close the centrifuge cover.
