9 Maintenance
9.1 Cleaning of the centrifuge
Attention!
• Pull the mains plug before cleaning.
• Before any cleaning or decontamination process other than that is recommended by the manufacturer,
the user has to ask the manufacturer if the planned process does not damage the device.
• For cleaning, water with soap or other water soluble mild detergent shall be used.
• One should avoid corrosive and aggressive substances. It is prohibited to use alkaline solutions,
inflammable solvents or agents containing abrasive particles.
• Do not lubricate the centrifuge motor shaft.
• The unused centrifuge should have cover opened.
Once a week
• Using wiping cloth, remove condensate or residues of the products from the rotor chamber.
Once a month
• Check the rotor clamping thread. In case of damage, replaced it.
• Check the centrifuging chamber whether it is damaged. In case of damage it cannot be longer put
into operation. Notify Service Center.
9.2 Maintenance of centrifuge elements
• The rotor pins shall be always lubricated with petroleum jelly.
• In this way, the uniform deflection of the buckets and quiet centrifuge operation is ensured.
Cleaning of the accessories
• In order to ensure safe operation, one shall carry out in
regular
way periodical maintenance of the
accessories.
• Rotors, buckets and round carriers have to withstand high stresses originating from the centrifugal
force. Chemical reactions as well as corrosion (combination of variable pressure and chemical
reactions) can cause destruction of metals. Hard to observe surface cracks increase gradually
and weaken material without visible symptoms.
Wipe rotor’s pins clean and dry with a paper towel after approx. 400 uses, cleaning or/and autoclav-
ing and then lubricate socket with the petroleum jelly.
• In case of observation of surface damage, crevice or other change, as well as the corrosion,
the given part (rotor, bucket, etc.) shall be immediately replaced.
• Clamping rotor, containers and reducer inserts must be cleaned regularly to prevent corrosion.
• Cleaning of the accessories shall be carried out outside of the centrifuge once every week or still
better after each use. For cleaning them one should use neutral agent of pH value 6÷8.
It is forbidden to use alkaline agent of pH > 8. Then, those parts shall be dried using soft fabric
or in the chamber drier at ca. 50°C.
• Angle rotor should be placed on a fabric with holes facing down, for effective drying.
• Do not use bleach on plastic parts of the rotor.
• In this way, the useful service life of the device is substantially increased and susceptibility to cor-
rosion is diminished. Accurate maintenance increases the service life as well and protects against
premature rotor failures.
Do not use bleach on plastic parts of the rotor.
According to laboratory standards, minimize the immersion time in each solution.
• Especially prone to the corrosion are parts made of aluminum.
• Corrosion and damages resulting from insufficient maintenance could not be subject of claims
lodged against the manufacturer.
• The unused rotor should have the lid removed.
HS accessories maintenance.
• Check the general condition of seals.
• Make sure that rubber O-rings are lightly coated with silicone grease. Use high vacuum grease.
• The rotor pins shall be always lubricated with
petroleum jelly
