Breakage of rotors can be caused evenby slightest damages.In case of rotors, buckets or tube racks getting in touch with corrosive substances the concernedspots have to be cleaned carefully.Corrosive substances are for instance: alkalis, alkaline soap solutions, alkaline amines,concentrated acids, solutions containing heavy metals, water-free chlorinated solvents, salinesolutions, e.g. salt water, phenol, halogenated hydrocarbons.Cleaning – units, rotors, accessories:- Turn the device off and disconnect it from the power supply before you beginany cleaning or disinfecting. Do not pour liquids into the housing interior.- Do spray disinfectant on the device.- Thorough cleaning not only has its purpose in hygiene but also in avoidingcorrosion based on pollution.- In order to avoid damaging anodized parts such as rotors, reduction plates etc.,only pH-neutral Detergents with a pH-value of 6-8 may be used for cleaning.Alkaline cleaning agents (pH-value > 8) must not be used.- After cleaning, please ensure all parts are dried thoroughly, either by hand or ina hot-air cabinet (max. Temperature + 50°C).- It is necessary to coat anodized aluminium parts with anti-corrosion oil regularlyin 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 be removed from the rotor chamber with a soft clothregularly.The maintenance procedure has to be repeated every 10 to 15 runs, but atleast 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-raysor other highenergy 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 can not be autoclaved at 134°C.
