FrontierTM Centrifuge FC5714/FC5718/FC5718R/FC5816/FC5816R EN-18- It is necessary to coat anodized aluminum parts with anti-corrosion oil regularly in order to increase their life-spans and reduce corrosion predisposition.- Due to humidity or not hermetically sealed samples, condensate may be formed. The condensate has to beremoved from the rotor chamber with a soft cloth regularly.The maintenance procedure has to be repeated every 10 to 15 runs, or at least once a week.- Connect the unit to the power supply, after the equipment is completely dry.- Do not carry out disinfection with UV-, beta- and gamma-rays or other high energy radiation.- Metal rotors can be autoclaved.- Rotor lid and adapters can also be autoclaved (max. 121°C, 20 min).- The tube racks are made of PP and cannot be autoclaved at 134°C.5.1.2 Cleaning and disinfection of the unit1. Open the lid before you turn off the unit. Disconnect it from the power supply.2. Open the rotor nut by turning the rotor key counter clockwise.3. Remove the rotor.4. For cleaning and disinfection of the unit and the rotor chamber use 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 to becoming brittle. Other components of the unit,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. Control the unit 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. Particularly 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.5. Dry the rotor cone with a soft, dry and lint-free cloth and look for damage. Do not grease the rotor cone.5.1.4 Disinfection of aluminum rotorsIn case of infectious material spilling into the centrifuge, the rotor and rotor chamber have to be disinfected directlyafter the run. Rotors may be autoclaved at a maximum temperature of 121°C.5.1.5 Disinfection of PP-rotorsAutoclavingThe 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 causereduction of the mechanical resistance of the plastic materialBefore autoclaving the PP-rotor and adapter must be thoroughly cleaned to avoid the burning in of dirty 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 notbe closed and must be totally unscrewedChemical sterilizationBottles, adapters and rotors may be treated with the usual liquid disinfectants.
