Centrifuge is one of the basic equipment commonly used in scientific research experiments. Today, we will follow Jiapeng technicians to learn about the precautions in the use of centrifuges. A centrifuge is a machine that uses centrifugal force to separate liquid and solid particles or components of a mixture of liquid and liquid. The centrifuge is mainly used to separate the solid particles in the suspension from the liquid, or separate the two liquids of different density and incompatible liquid in the emulsion (for example, separating the cream from the milk); it can also be used to exclude Liquid in wet solids, such as wet clothes in a washing machine; special ultra-speed tubular separators can also separate gas mixtures of different densities; use different density or granularity of solid particles to set different velocity in liquid, some sedimentation Centrifuges can also classify solid particles by density or particle size. Centrifuge notes: 1. In order to ensure safety and centrifugal effect, the instrument must be placed on a solid horizontal surface. No items should be placed on the engineering plastic cover door; the samples must be placed symmetrically and the nut must be tightened before starting the machine. 2. Before use, check the rotor for any flaws, corrosion, etc. At the same time, check the centrifugal cup for cracks, aging, etc. If you find any doubt, stop using it immediately and contact the factory; be sure to tighten the rotor before starting the machine. Press the nut to prevent the high-speed rotating rotor from flying out and causing an accident. 3. The speed setting must not exceed the maximum speed to ensure the safe operation of the machine. 4. If 0.00 or other digits appear during use, the machine will not run, shut down and power off, restart after 10 seconds. After the set speed is displayed, press the operation button again, the machine will run as usual. 5. If the specific gravity of the sample to be separated exceeds 1.2 g/cm 3 , the maximum speed N must be corrected as follows: N = NMAX * (1.2 / sample specific gravity) 1/2, NMAX = rotor limit speed. 6. Do not open the door during the operation of the machine or the rotor is not stopped to avoid accidents. 7. The centrifuge cup must be filled with the same amount of sample. Do not run the rotor under unbalanced conditions. 8, the centrifuge should not be more than 60 minutes at a time. 9. The centrifuge must be grounded reliably; if the machine is not in use, unplug the power cord. Dear Customer: Thank you for your interest in Shanghai Jiapeng's products.
