4. Cleaning and Maintenance
Rotor
If a rotor is exposed to acid or basic liquid, it gets damaged. In case rotor weight is imbalanced due
to corrosion, serious vibration and noise can happen when high speed rotating. Furthermore, it can
damage a drive shaft.
Rotor has good corrosion resistance in the atmosphere but its corrosion can be influenced by humidity,
salt content and impurities volume in the atmosphere.
Rotor is resistant to neutral aqueous solution such as carbonate, chromate, acetate and sulfide,
but it is not well resistant to chloride solution.
Also, its corrosion is getting faster due to increase in hydrogen ion concentration and it is eroded by
sulfuric acid and phosphoric acid and especially it is eroded faster by hydrochloric acid.
1. Corrosion of rotor and surface treatment
2. Rotor maintenance
Cleaning : In case a rotor is exposed to sample coming out of tube, clean it with a soft cloth soaked with
warm water immediately. At this moment, make sure do not scratch the surface treated specially.
Drying : Keep a narrow groove of a rotor dry with care. Hair dryer will be more effective for drying.
Keeping : Keep a rotor on a clean and dry place. Especially, a lid of angle rotor should be separated and
keep its body upside down.
Check sealing condition before use.
In case a lid screw of aerosol-tight rotor and sealing ring in pit parts are worn out, replace a rotor lid.
Check a sealing ring periodically to protect a rotor.
Keep aerosol-tight rotor with its lid loosened.
3. Aerosol-tightness
Rotor, its lid and bucket can be autoclaved (121
℃
, 20mins).
4. Rotor sterilization and disinfection
Drive shaft
1. To keep efficiency of refrigeration system, radiator should be protected from dust or other contaminant.
Otherwise, it can cause decline in refrigeration function.
You should clean radiator once every three months.
Waste disposal
1. This centrifuge should not be scraped for household and you are forced to comply with local wastes law.
