The principle and use of large-capacity high-speed refrigerated centrifuge

1. Principle: Large-capacity high-speed refrigerated centrifuge is a special centrifuge that can be used to quickly freeze samples. Its principle is based on the principles of centrifugal separation and high-speed freezing.
First, the sample is loaded into the rotor of a centrifuge. When the rotor begins to rotate, the sample is subjected to centrifugal force, separated and deposited in the centrifuge tube. The centrifuge then uses a freezing gas (commonly liquid nitrogen or liquid argon) to quickly freeze the sample in the tube, bringing it to ultra-low temperatures quickly.
The rapidity and efficiency of the process make high-capacity high-speed refrigerated centrifuges a must-have for many laboratories, especially in analyzes and research involving plant materials, as the equipment can quickly preserve the viability of the sample and protect it from oxidation or Other injuries.

2. How to use:

1）Preparation: First clean the refrigerated centrifuge, confirm whether the centrifuge tube and rotor are clean and free of foreign matter, and assemble the centrifuge wheel and centrifuge tube.
2）Set parameters: Set the temperature, speed, time and other parameters according to the type of sample to be separated and the centrifugation parameter requirements.
3）Load the sample: Load the sample into a centrifuge tube and distribute it fully and evenly in the centrifuge tube, trying to avoid excessive gaps between tubes.
4）Load the sample: Insert the centrifuge tube containing the sample into the corresponding centrifuge hole in the centrifuge. Pay attention to the installation direction and the distance between the tubes.
5）Start the centrifuge: Press the start button, the centrifuge begins to accelerate and gradually reaches the set speed. During the operation, you can observe the operation of the centrifuge and pay attention to whether there are any abnormalities in the centrifuge.
6）End centrifugation: Stop the centrifuge after the set time, take out the centrifuge tube, take out the sample, and proceed to the next experiment or storage as soon as possible.
7）Clean the centrifuge: Clean the centrifuge tubes and rotors, and thoroughly remove residual samples and liquids to ensure that they are clean and free of foreign matter the next time they are used.
8）Turn off the centrifuge: After cleaning, turn off the power of the centrifuge and cut off the power to ensure the safe use of the centrifuge.
