Centrifuge use precautions

Centrifuge is an instrument that separates samples, and can be widely used in medical, biological, agricultural and other instruments, and can be divided into high-speed centrifuges, refrigerated centrifuges, ultra-high-speed centrifuges.

At present, laboratories often use electric centrifuges to rapidly rotate electric centrifuges, and they must pay attention to safety. In particular, during the operation of centrifuges, it is necessary to prevent centrifuges from moving while they are working due to imbalance or aging of the test tubes. When the table falls off or the lid is not covered and the centrifuge tube breaks due to vibration, the glass fragments fly out and cause an accident. Therefore when using a centrifuge, the following actions must be taken into account.

(1) The bottom of the centrifuge tube should be filled 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 immediately.

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

(4) When starting the centrifuge, the top cover of the centrifuge should be covered before it can be started slowly.

(5) After the separation is completed, close the centrifuge first. After the centrifuge stops rotating, open the centrifuge cover and take out 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.
