Sigma centrifuge maintenance and troubleshooting methods

How does sigma maintain the centrifuge:

I. Maintenance and maintenance of the experimental centrifuge:

1. Clean the rotor chamber and rotor with water or a mild detergent. Do not use alkaline solution or solvent that is abrasive to the material. Wash with clean water and dry the centrifuge chamber with a dry cloth.

2. Open the top cover when the centrifuge is not in use, keep the rotor chamber dry to avoid motor bearing wear.

3. Use a rag or tweezers to remove debris from the rotor chamber.

4. Special safety measures must be taken when centrifuging toxic, radioactive, and contaminated samples.

2. Maintenance methods for medical centrifuge accessories:

1. The centrifuge should keep a certain distance from other electrical equipment, and have good grounding measures, and conduct regular inspections.

2. Centrifuges and rotors must not be exposed to high levels of UV radiation or exposed to heat for extended periods of time. Apply a neutral detergent when cleaning.

3. The rotor can be replaced if needed. After reinstallation, tighten the turnbuckle screws.

4. If a centrifuge tube shows color change, deformation, leakage, etc., it must be stopped.

5. Do not screw on the cap when performing high temperature and high pressure sterilization on the centrifuge tube to avoid deformation of the tube. See the section of this user manual for the temperature tolerance of each centrifuge tube.

3. Maintenance method of medical centrifuge condenser:

1. The condenser is used to cool the refrigerant and is installed at the rear of the centrifuge, using air cooling.

2. The condenser should be cleaned of dust regularly to avoid heat transfer. It can be purged here with compressed air.

4. Maintenance method of the rotating pin of the medical centrifuge: the rotating pin should be lubricated with lubricating oil to ensure the smooth running of the centrifuge.

5. Sterilization and disinfection methods for medical centrifuge rotor chambers and accessories: All conventional disinfectants can be used. Since the centrifuge and accessories are made of different materials, the compatibility of the disinfectant must be considered.

6. The centrifuge of the medical centrifuge should ensure that the important parts of the centrifuge are intact, mainly: the motor suspension is stable, the rotor and accessories are not corroded, the shaft is not deviated, the screw connection is fastened and the grounding is good.

Centrifuge troubleshooting method:

1. The decrease in vacuum is a common failure. For high-speed, ultracentrifuges, most of them are equipped with a vacuum device, in order to make the centrifugal chamber in a medium or high vacuum state during operation, reducing friction on the rotor and making it stable. When the vacuum is lowered or the vacuum is not good, check the vacuum system. Generally, the oil is replaced and the vacuum is restored.

2, small or desktop centrifuge, often forget to take the rotor placed in the centrifuge cavity, take a long time, the rotor will be stuck on the shaft.

3. During the operation of the high-speed and ultra-speed centrifuge, there is a fault prompt on the panel, and the fault can be handled for the corresponding fault prompt. Proper operation and reasonable maintenance are the key to ensure the normal operation of the instrument and extend the service life of the instrument. Centrifuges with superior performance must be properly operated and routinely maintained. Usually, you should observe the running status, listen to the sound, diagnose regularly, and deal with it in time to reduce the failure rate and extend the service life, so that the centrifuge can exert its efficiency.
