6. MAINTENANCE
Please use safety gloves for the following work
6.1 General cleaning of the centrifuge
Before cleaning the centrifuge, users are advised to wear safety gloves to minimise the risk of
irritation. For general cleaning, water mixed with a mild detergent is sufficient. Do not use any
corrosive substances or abrasive cloths to clean the centrifuge. Do not use alkaline solutions,
flammable solvents or agents containing abrasive particles.
6.2 Cleaning of the accessories
It is recommended that rotors are regularly cleaned to ensure optimum performance and
prolong their life. This should be done with a non-corrosive cleaning agent (between 6 and 8pH)
as these can weaken the rotor. When cleaning the rotor please pay particular attention to the
holes of the rotor.
If cracks appear in the rotor, we recommended that the rotor be replaced immediately. Rotors
have to withstand high stresses of centrifugal force and therefore any slight damage would be
made worse during operation and inadvertently cause damage to the machine.
All accessories used in the centrifuge, such as sample containers, should be clean and free of
debris. The sample tubes should also be dry before use in the centrifuge.
6.3 Sterilisation and disinfection of the bowl and accessories
When sterilising the bowl and rotors, users should take into account the material of these items
and be sure that the chemicals in the cleaning agents will not react with them. Furthermore,
when autoclaving the rotors, users should consider the temperature resistance of the material
used in construction. The optimum temperature for autoclaving rotors used in this centrifuge is
between 121ºC and 124º C. When autoclaving users should also make sure not to exceed 215
kPa (2.15 bar) of pressure. The recommended time for autoclaving is 15 minutes.
The user is responsible for proper disinfections of the centrifuge, particularly if some dangerous
material is spilled inside or outside of the centrifuge. During above mentioned works you must
always wear safety gloves.
MSE appointed engineers or workshop personnel should not touch the centrifuge unless it has
been de-contaminated and a certificate is signed by some one in authority to that effect.
6.4 Tube cracking
It is recommended that users operate in a clean environment to reduce the risk of any debris
entering your centrifuge system. Debris can crack tubes and rotors and also damage the
centrifuge itself.
