[Chemical Knowledge]：Precautions for the use of centrifuges

Read： 753 Time：8months ago Source：Transform the World with Simplicity

Centrifuge is a commonly used equipment in the laboratory, mainly used for sedimentation, separation and acceleration of material centrifugation. In laboratory work, centrifuges are often used, but in the process of using centrifuges, special attention should be paid to some matters to ensure the accuracy and safety of the experiment. The following will introduce the use of centrifuges need to pay attention to matters.

When using the centrifuge, you must follow the instructions, read the instructions of the centrifuge carefully, and understand the function of each button and operation. In addition, to ensure that the rotating parts of the centrifuge are intact, check the centrifuge cup for cracks or damage. For high-speed centrifuges, special attention should be paid to the installation and fastening of the rotor to avoid serious accidents due to the loss of balance of the rotor.

when using a centrifuge to select the appropriate centrifuge tube. When filling the liquid, be sure to keep the inside and outside of the tube clean to avoid splashing when the liquid rotates at high speed.

the amount of liquid in the centrifuge tube must meet the requirements of the centrifuge, too much or too little liquid will affect the effect of centrifugation.

to keep the inside and outside of the centrifuge tube clean to avoid stains affecting the experimental results.

Third, pay attention to balance during the use of centrifuges. Different types of centrifuges need to maintain balance, especially high-speed centrifuges, high speed, centrifugal force, the balance of the rotor for the experimental results are more obvious. When using the centrifuge, ensure that the centrifuge is placed on a stable work surface, and it is strictly prohibited to move the centrifuge in operation.

In addition, pay attention to safety when using centrifuges. The high-speed rotation of the centrifuge will produce greater centrifugal force, so be sure to wear a lab coat and goggles when using it. In the process of operation, to avoid the hand a long time close to the rotating parts, so as to avoid danger.

after using the centrifuge to carry out timely cleaning and maintenance. After the experiment is completed, the power of the centrifuge should be turned off in time, and the centrifuge tube and the inside of the centrifuge should be cleaned. For high-speed centrifuges, the rotor should be regularly balanced and tested, and regular maintenance should be carried out to ensure the normal use of the centrifuge.

need to pay attention to a series of matters when using the centrifuge, including the correct operation, select the appropriate centrifuge tube, maintain balance, pay attention to safety and timely cleaning and maintenance. Only by doing these precautions can the safe use of the centrifuge and the accuracy of the experimental results be ensured. I hope everyone can pay more attention when using the centrifuge to ensure the safety of the laboratory and the accuracy of the experimental results.
