FrontierTM Centrifuge FC5707 EN-173. Remove the rotor.4. Cleaning and disinfect the unit and the rotor chamber using the above mentioned cleaner.5. Clean all accessible areas of the device and its accessories, including the power cord with a damp cloth.6. Wash the rubber seals and rotor chamber thoroughly with water.7. Rub the dry rubber seals with glycerol or talc to prevent these from becoming brittle. Other components of theunit, e.g. the lid lock, motor shaft and rotor must not be greased.8. Dry the motor shaft with a soft, dry and lint-free cloth.9. Check the equipment and accessories for damage.Make sure that the centrifuge is turned off the unit and disconnect the unit from the power supply. Then removeadherent dust from the ventilation slots in the centrifuge by using a soft brush. Do this at least every six months.5.1.3 Cleaning and disinfection of the rotor1. Clean and disinfect the rotors, rotor lids and adapters with the above mentioned cleaner.2. Use a bottle brush to clean and disinfect the rotor bores.3. Rinse the rotors, rotor lid and adapter with clear water. Particular the drillings of angle rotors.4. For drying of the rotors and accessories set them on a towel. Place the angle rotors with bores down, to drythem to.5. Dry the rotor cone with a soft, dry and lint-free cloth and look for damage. Do not grease the rotor cone.6. Put the dry rotor back on the motor shaft.7. Fix the rotor by turning the rotor nut clockwise.5.1.4 Disinfection of aluminum rotorsIn case of infectious material spilling into the centrifuge, the rotor and rotor chamber have to be disinfected rightafter the run. Rotors may be autoclaved at a maximum temperature of 121°C.5.1.5 Disinfection of PP-rotorsAutoclavingDuring autoclaving, it´s quite possible that plastic parts, i.g. rotor, can become deformed!The recommended time for autoclaving: 15 – 20 min at 121°C (1 bar)ATTENTION:The sterilization time of 20 min. must not be exceeded. Repeated sterilization will cause reduction ofthe mechanical resistance of the plastic materialBefore autoclaving the PP-rotor and adapter must be thoroughly cleaned to avoid the burning in ofdirty residues.You can disregard the consequences of some chemical residues to plastic materials at ambient temperatures. Butat the high temperatures during autoclaving those residues may corrode and destroy the plastic. The objects mustbe thoroughly rinsed with distilled water after the cleaning but before the autoclaving. Residues of any cleaningliquids may cause fissures, whitening and stains.Gas sterilizationAdapters, bottles and rotors may be gas sterilized with Ethylenoxyd. Make sure to air out the items after thesterilization and before using them again.ATTENTION:Because the temperature may rise during the sterilization, rotors, adapters and bottles must not beclosed and must be totally unscrewed.Chemical sterilizationBottles, adapters and rotors may be treated with the usual liquid disinfectants.ATTENTION:Before applying any other cleaning or decontamination method than recommended by themanufacturer, contact the manufacturer to ensure that it will not damage the unit or the rotor.5.1.6 Glass breakageWith high g-values, the rate of glass tube breakage increases. Glass splinters have to be removed immediatelyfrom rotor, buckets, adapters and the rotor chamber itself. Fine glass splinters will scratch and therefore damagethe protective surface coating of a rotor. If glass splinters remain in the rotor chamber, fine metal dust will build up
