The frozen high-speed centrifuge is a microcomputer-controlled, DC brushless motor. It is a special equipment for rapid separation of mixed liquids. It can be widely used in scientific research, genetic engineering, genetics, life science, biochemistry, medical and other units, and conducts biochemical tests for separation of suspensions. . The machine is easy to operate and has a fast cooling speed. It is suitable for experiments with low separation, high centrifugal requirements and low temperature.
Freezer high speed centrifuge operating procedure
1. Place the centrifuge on a flat table or platform, visually measure it to be in a horizontal state, and gently shake the centrifuge by hand to check if the centrifuge is placed smoothly.
2, open the door cover, gently put the rotor on the motor shaft, tighten the nut to make the rotor and the motor shaft tightly connected (note that the action should be careful and gentle, avoid large and large shaking and pull-up pressure, so as not to damage the motor Flexible support), after gently rotating the rotor body by hand, the rotor should be flexible.
3. Place the centrifuge tube into the test tube and place it in the test tube hole. The centrifuge tube must be placed in even symmetry, and the test solution in the tube must be uniform to ensure balanced operation of the instrument.
4. Turn on the power and turn on the power switch on the right side of the control panel.
5, set the temperature: press the temperature button, the temperature display window, the digital tube flashes, press the â–³ â–½ button to set the temperature, then press the temperature button, the time window digital display, and then press the temperature button to exit. At this time, the compressor starts to start cooling. When cooling, the centrifuge speed can be set to about 2000r/min to start at no load. After cooling to the set temperature, put it into the centrifuge tube, centrifuge at high speed and time, and press the start button.
6. Speed, time setting: Press the speed window â–³ â–½ key to set the speed, press the time window â–³ â–½ key to set the time, press the start key, the centrifuge slowly starts to set the speed. During the operation timing, the buzzer beeps and the machine stops working. In case of emergency during operation, press the stop button, the centrifuge stops running, and the buzzer does not ring.
7. When the rotor is completely stopped, the door can be opened and the centrifuge tube removed carefully to complete the separation process.
8. Turn off the power switch and turn off the power to the centrifuge.
Frozen high speed centrifuge notes
1. To ensure safety and centrifugal effects, the instrument must be placed on a sturdy, shock-proof, level surface and ensure that the four corners are balanced.
2. The centrifuge tubes must be placed symmetrically. The solution in the tubes must be uniform and the screws connecting the rotor and the motor shaft must be tightly tightened.
3. Do not move the centrifuge during the operation. Do not open the door.
4. Do not open the door when the motor and rotor are not completely stopped.
5, the instrument must have a reliable grounding.
6. After the separation is finished, the instrument should be wiped clean in time, and the power switch of the instrument is turned off and the power plug is unplugged.
7. When removing the rotor, you must use the special handle provided with the machine, or gently tap the rotor body with a non-metallic tool (such as a screwdriver handle), and repeat until the connection between the loose rotor and the motor shaft. Do not loosen. After the nut is directly pulled up by hand, so as not to damage the flexible support of the motor.
8. Before each operation, carefully check the rotor and the centrifuge tube for cracks, aging, etc., and replace if necessary.
9. If there is water in the cavity of the centrifuge, dry it with a dry cloth to keep the cavity clean.
