What are the Common Operations to Prolong the Life of a Refrigerated Centrifuge

 

Centrifuges, also known as precipitators, include separation-type centrifuges for quickly separating suspended substances in liquids, large-scale preparative centrifuges for concentrating and purifying particles, and low-speed analysis centrifuges for experimental analysis. Although there are different types of centrifuges, the functions can be categorized as separation, concentration, purification and analysis.

 

Nine ways to prolong the life of the refrigerated centrifuge.

 

  • After centrifugation, the water in the centrifugal chamber should be wiped dry, and a little neutral lubricating grease should be applied to the cone surface of the motor spindle every week to prevent the shaft from resting. If the refrigerated centrifuge is not used for a long time, the rotor should be taken out, wiped clean and placed in a dry place to prevent rust.

 

  • The main power plug should be removed when the instrument is not used for a long time or when it is being repaired. Otherwise, the instrument will be electrified, and safety accidents may occur especially during maintenance.

 

  • In order to protect the refrigeration compressor of the refrigerated centrifuge, the interval between the instrument disconnection and power-on must be greater than 3minutes, otherwise the compressor will be damaged.

 

  • When the rotor is not in use, in should be taken out of the centrifuge chamber, cleaned and dried with neutral detergent in time to prevent chemical corrosion, and stored in a dry and ventilated place. It is not allowed to scrub the rotor with non-neutral detergent, and it is not allowed to dry the rotor with electric hot air. A little grease should be applied to the center hole of the rotor for protection.

 

  • In order to ensure the freezing effect, when the ambient temperature is higher than 30℃, the rotor and the centrifugal chamber should be pre-cooled, and the rotor should be operated at a speed of 15% less than the original speed.

 

  • The centrifuge tube should be updated regularly, and it is strictly forbidden to use the centrifuge tube that is on the verge of rupture.

 

  • Before each use, pay attention to check the rotor for corrosion points and micro-cracks. It is forbidden to use the rotor that has been corroded or cracked, and use the rotor that has exceeded the shelf life to ensure personal safety.

 

  • When using the centrifuge rotor, make sure that the set rotor number is correct. If the rotor number is set incorrectly, it will cause the rotor to be used at overspeed or it will not achieve the desired centrifugation effect. In particular, the vicious accident that the rotor may burst when the rotor is used at excessive speed should not be neglected.

 

  • Polypropylene (PP) centrifuge tubes or bottles cannot be used in contact with aqua regia, toluene, benzene, gasoline, kerosene, etc. Ultra-clean workbench polycarbonate (PC) centrifuge tubes or bottles cannot be mixed with hydrofluoric acid, hydrochloric acid (30%, 50%), sulfuric acid (10%), potassium hydroxide, magnesium hydroxide, ammonium hydroxide, fluoride contact use of aluminum, ammonium sulfide, ammonium acetate, ammonium carbonate, chromic acid (50%), toluene, benzene, gasoline, acetaldehyde, acetone, ethanol, isobutanol, cresol, etc. Polyethylene (PE) centrifuge tubes or bottles cannot be used in contact with sulfuric acid (50%, 75%), benzene, gasoline, kerosene, etc.
