Precautions when operating the electric centrifuge

The speed of the electric centrifuge is fast. Pay attention to safety. In particular, during the operation of the centrifuge, due to unbalance or aging of the test tube pad, the centrifuge will move while working, and it will fall from the test bed consistently or because the cover is not covered. After the centrifuge tube ruptured due to vibration, the glass fragments spun out and caused an accident. Therefore when using a centrifuge, the following actions must be taken into account.

1) The bottom of the centrifuge tube should be covered with cotton or test tube pad.

2) If there is noise or vibration of the body in the electric centrifuge, the power should be cut off immediately to eliminate the malfunction.

3) Centrifugal tubes must be placed symmetrically in the casing to prevent vibration of the fuselage. If only one sample tube is to be replaced with an equal mass of water

4) When starting the centrifuge, it should be covered with a centrifuge cover before it can start slowly

5) After the separation is completed, turn off the centrifuge first. After the centrifuge stops rotating, open the centrifuge cover and remove the sample. Do not force it to stop using external force.

6) Centrifugation time is usually 1 to 2 minutes. During this period, the experimenter must not leave to do anything else

Many of the commonly used low-speed centrifuges have also entered the laboratory. In the research institutes of enterprises or institutions, low-speed experimental centrifuges with rotation speeds of around 3,000 rpm have been commonly used, such as the 315-type filtration sedimentation integrated experimental centrifuge, and the 100-type experiment. Centrifuges, 200-type centrifuges, etc. These centrifuges are well-designed, have a low center of gravity, and are safe and stable. They have gained greater application in the analysis of pre-test samples in the chemical, food, and medical fields.
