At present, the laboratory is commonly used desktop electric centrifuges, desktop electric centrifuges fast rotation, pay attention to safety, in particular, to prevent the centrifuge during operation, due to imbalance or aging test tube, while the centrifuge while moving, Caused by falling from the test bench, or because the lid is not covered, the centrifugal tube ruptures due to vibration, and the glass fragments fly out and cause an accident. Therefore, when using the desktop motorized centrifuge, the following must be noted:
(1) Put cotton or test tube pad on the bottom of the sleeve.
(2) If there is noise or vibration of the fuselage, 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 body. If only one sample tube is to be replaced by another water of equal quality.
(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.
Bench-top electric centrifuges are widely used in biochemical, pharmaceutical, agricultural science, animal husbandry, food hygiene, environmental protection, pharmaceutical products and other production and research institutes, to separate particles of different densities; platelets, serum, plasma, urea, etc. for qualitative Analysis, ideal equipment for radioimmunoassay.
