Q&A about centrifuge

Oct 25, 2019

Proper use of the centrifuge can extend its life, minimize damage, and reduce our experimental progress. We may have the following doubts.

Question 1: What should I pay attention to when placing the centrifuge?

A: Centrifuges are generally placed in a dry place away from direct sunlight. Centrifuge heat dissipation is relatively large, do not pile up debris around, surrounded by walls, baffles and other airtight, heat-dissipating items at least 10cm. At the same time, the centrifuge should be placed in a room as far as possible. Never put organic reagents or flammable materials around. As shown in Figure 1 above, the centrifuge is damaged and the air waves are generated, causing the medicine cabinet to oscillate. Fortunately, the organic reagents Did not spill, otherwise the consequences will be more serious.

Question 2: What is the most important thing when using the centrifuge, what is the most critical step?

A: After the start of the centrifuge work, it is similar to a pistol. It is similar to a bomb. Therefore, in the event of an accident, it is quite dangerous. The high-speed or ultra-high-speed rotating rotor flies out and can almost penetrate everything. So nothing is the most important and crucial.


Question 3: What should we pay attention to as a user?

A: As a user, we should use a special centrifuge tube for the liquid containing organic reagents according to the centrifuge tube required for the experiment; select the appropriate rotor, the speed is absolutely prohibited to exceed the maximum speed indicated by the rotor, in the above figure The accident was caused by a mistake in the use of the rotor. The correct use of the centrifuge tube and the rotor is critical, especially the symmetrical placement and weight trimming of the centrifuge tube. At the same time, the maximum weight of the centrifuge tube and the rotor can be taken care of. The liquid can hold up to 3/4 of the full volume of the centrifuge tube. Many accidents are caused by improper use of the rotor and the centrifuge tube.
