ALLWEILER What are the operation modes of centrifuge

1. When using various centrifuges, it is necessary to carefully balance the centrifuge tube and its contents on the balance in advance. When balancing, the difference between the components shall not exceed the range specified in the instructions for each centrifuge. Each centrifuge has its own allowable difference for different turns. It is certain that odd number of tubes cannot be loaded in the turn. When the turn is only partially loaded, It is necessary to place the pipes symmetrically in the head so that the load is evenly distributed around the head.

2. To centrifuge at a temperature lower than room temperature. Before use, turn back should be placed in the refrigerator or in the turn back room of the centrifuge for precooling.

3. Do not leave at will during the centrifugation process. Observe whether the appearance of the centrifuge works normally at any time. If there is abnormal sound, stop the machine immediately to check and remove the fault in time.

4. Each turn back has its own high allowable speed and cumulative time limit for use. When using turn back, refer to the instruction book, and do not use too fast. Every turn back must have an application file to record the accumulated application time. If the high operation limit of the turn back is exceeded, the speed must be reduced according to the rules.

5. When loading the solution, it should be carried out according to the specific operation instructions of various centrifuges. Appropriate centrifuge tubes should be selected according to the nature and volume of the liquid to be centrifuged. Some centrifuge tubes have no caps, and the liquid should not be loaded too much to prevent throwing out during centrifugation, forming back imbalance, rust or corrosion. However, it is often necessary to fill the centrifuge tubes of the preparatory ultracentrifuges with liquid, Avoid the deformation of the upper part of the plastic centrifuge tube during centrifugation. After each use, it is necessary to carefully check the turning back, clean and dry it in time. Turning back is a key part of the centrifuge that needs to be protected. When moving, be careful not to collide to avoid the formation of scars. When turning back for a long time, apply a layer of polish protection. It is prohibited to use centrifuge tubes that are significantly deformed, damaged or aged.

ALL WEILER Alveller centrifuge is an instrument for separating samples, which is widely used in biomedical, petrochemical, agricultural, food hygiene and other fields. It uses the difference in the precipitation speed of different substances in the centrifugal force field to achieve the separation of samples. It is an indispensable test equipment for the sample pretreatment process. Correct use and maintenance can ensure the smooth progress of the test, thus improving the power of the laboratory.

Daily maintenance of centrifuge

Before centrifuge operation, cut off the power supply and release the brake of the centrifuge. You can manually test rotate the drum to see if there is any biting brake condition;

Check whether other parts are loose and abnormal;

Turn on the power supply and start the car clockwise (it usually takes about 40-60 seconds from static state to normal operation);

Generally, each equipment must operate for about 3 hours without load after arriving at the factory, and can operate without abnormal conditions;

Materials shall be placed evenly as far as possible;

It is necessary to assign special personnel for operation, and the capacity shall not exceed the quota.

It is forbidden to operate the machine over speed to avoid affecting the service life of the machine;

After the machine is started, if there is any abnormal condition, it is necessary to stop the machine for inspection, and if necessary, it is necessary to disassemble, clean and repair it;

ALLWEILER centrifuge is operated at high speed, so you must not touch its drum with your body to prevent accidents;

The mesh number of the filter cloth should be determined according to the size of the solid particles of the separated material, otherwise the separation effect will be affected. Filter cloth shall be installed when other filter cloth is installed; The sealing ring is embedded in the drum sealing groove to prevent materials from running in;

To ensure the normal operation of the centrifuge, please refuel and maintain the rotating parts every 6 months. Check the smooth operation of the bearing and check whether there is wear; Check whether the parts in the braking equipment are worn, and replace them if serious; Whether the bearing cover has oil leakage; After the machine is used, clean it and keep it tidy;

Do not separate non anti-corrosion centrifuge from highly corrosive materials; Others shall be operated in strict accordance with equipment requirements and rules. Non explosion proof centrifuges must not be used in flammable and explosive places.
