The vertical low-speed large capacity centrifuge is an important technological innovation in the laboratory field in recent years, which has high efficiency and stable centrifugal force, and can meet the centrifugal needs of large capacity samples. The vertical design makes sample separation more uniform and reduces sample loss during centrifugation. Meanwhile, low-speed operation reduces the heat generation of the sample and protects the integrity of the thermosensitive sample.

The correct use of a vertical low-speed large capacity centrifuge can ensure the accuracy and reliability of experimental results. The following is a detailed explanation of the correct usage method.

1. Choose appropriate rotational speed and centrifugal force: Before use, it is necessary to first understand the centrifugal force and rotational speed required for the experiment. Select appropriate parameter settings based on the properties of the sample and experimental requirements. Ensure that the speed and centrifugal force do not exceed the rated values of the equipment to avoid equipment damage or sample breakage.

2. Sample preparation: Before conducting centrifugation experiments, ensure that the sample is ready and properly labeled. Place the sample in a centrifuge tube and ensure that the lid is tightly closed to prevent leakage or contamination of the sample during centrifugation.

3. Balanced sample: Before placing the sample into this device, ensure that the sample is evenly distributed in the centrifugal rotor. If the centrifugal rotor is adjustable, ensure that the sample is in the symmetrical position of the rotor. If the centrifugal rotor is not adjustable, balance can be achieved by placing equal weight samples in opposite relative positions.

4. Close the hood: Before placing the sample, ensure that the hood is properly closed and locked. This can ensure the safety and stability of the centrifuge during the centrifugation process.

5. Set centrifugal parameters: According to experimental requirements, set the rotational speed and centrifugal time. Make sure to choose the appropriate centrifugation mode, such as pre cooling mode or heating mode, to meet the experimental requirements.

6. Start the centrifuge: After confirming that all parameter settings are correct, start the equipment. Ensure that there are no abnormal noises or vibrations during the startup process. If any abnormal situation is found, it should be stopped immediately and the cause checked.

7. Operation after centrifugation: After centrifugation, wait for the machine to stop running, and then carefully open the hood. Use gloves and other appropriate personal protective equipment, carefully remove the centrifuge tube, and transfer the sample to another container.

8. Cleaning and maintenance: Clean the centrifugal rotor and interior promptly after use. Follow the cleaning and maintenance guidelines provided by the manufacturer to ensure normal operation and longevity.

Vertical low-speed large capacity centrifuge is a powerful experimental tool, but the correct usage method is crucial. Following the above steps can ensure the success and safety of the centrifugation experiment. Before use, it is essential to read and understand the operating manual of the equipment, and follow the relevant safety operating procedures.
