High speed desktop centrifugeIt is a core equipment in the fields of biological experiments, clinical testing, etc. Its internal cavity, rotor and other components directly contact the sample, and incomplete cleaning and disinfection can easily cause cross contamination. Improper storage can shorten the service life of the equipment. Establishing a standardized system of "immediate cleaning after use, regular deep disinfection, and scientific storage when idle" is the key to ensuring reliable experimental results and stable equipment operation.

Daily cleaning should focus on "no residue, anti-corrosion" throughout the entire experimental process. After each centrifugation, turn off the power and wait for the rotor to come to a complete stop before removing the sample tube. Use a clean absorbent paper or dust-free cloth to wipe the surface and inner cavity of the rotor for any residual sample liquid or condensate. If there are any viscous residues such as proteins, gently wipe with a gauze dipped in 20% ethanol to avoid damaging the rotor surface by hard scraping. The inner wall of the centrifuge chamber needs to be cleaned once a week, wiped with a soft cloth soaked in neutral detergent solution (such as 0.1% detergent), and then wiped with pure water to remove residual detergent. Finally, open the hood and ventilate for 30 minutes until the inner chamber is dry. Wipe and disinfect the operation panel and body shell with 75% medical alcohol to prevent fingerprints and stains from accumulating and affecting operation.

Deep disinfection should be implemented according to the classification of pollution levels, with a focus on preventing and controlling microbial contamination. For centrifuges used in routine experiments, ultraviolet disinfection should be performed once a month. The ultraviolet lamp should be placed inside the centrifuge chamber, and the machine cover should be closed and irradiated for 30-60 minutes. After disinfection, ventilation should be carried out for 20 minutes to remove ozone residues. If you have come into contact with high-risk samples such as pathogenic microorganisms and blood samples, chemical disinfection should be carried out immediately: soak the rotor and basket in a chlorine containing disinfectant containing 500mg/L effective chlorine for 30 minutes, remove them, rinse them with sterile water, and dry them; Spray the inner wall of the centrifuge chamber with the same concentration of disinfectant spray, wipe it with sterile gauze after 20 minutes, and then carry out ultraviolet disinfection. After disinfection, it is necessary to record the disinfection time, pollutant type, and operator to form a traceable file.

Standardized storage is an important part of long-term maintenance of equipment. When idle for a short period of time (1-2 weeks), it is necessary to ensureHigh speed desktop centrifugeThe inner cavity is dry and free of debris. After cleaning and drying the rotor, put it back in place, turn off the power and unplug the plug. Cover the body with a dust cover and place it in a ventilated and dry corner of the laboratory to avoid direct sunlight. When idle for a long time (more than one month), comprehensive maintenance is required: disassemble the rotor and basket, clean and disinfect them, apply rust proof oil to the metal parts, and store them separately in a dedicated packaging box; Place moisture-proof agent inside the centrifuge chamber, leave a 5-10cm gap on the machine cover for air circulation, and prevent mold growth; Regularly (every 2 weeks) power on and run for 5 minutes to avoid dry and rusty motor bearings.

Special circumstances handling and precautions cannot be ignored. If the sample tube ruptures, immediately shut down the machine and cut off the power. Wear gloves and goggles, pick up the broken glass with tweezers, wipe the contaminated area with gauze dipped in disinfectant, and finally use a vacuum cleaner to remove small glass debris. Direct contact with hands is strictly prohibited. When cleaning and disinfecting, it is necessary to avoid water infiltration into the motor and circuit interfaces. If water accidentally enters, professional maintenance personnel should be contacted immediately. The rotor needs to be regularly inspected for wear. If surface scratches, corrosion, or loose threads are found, they should be replaced in a timely manner to prevent breakage accidents during high-speed operation.

　　High speed desktop centrifugeThe core of the cleaning, disinfection, and storage standards lies in "immediate handling, regular reinforcement, and scientific protection". Strictly following this specification can effectively avoid cross contamination, ensure the accuracy of experimental data, and extend the service life of equipment, providing a solid guarantee for the safe and efficient operation of the laboratory.
