Eppendorf 5702 RH Centrifuge - Manual (Page 17)

The outer surfaces of the centrifuge and the rotor chamber should be cleaned regularly with a mild cleaning agent. This is
for hygiene purposes and to prevent adhering impurities causing corrosion.
If material hazardous to health or aggressive material contaminate the device, the owner is responsible for appropriate
cleaning and decontamination.
Before cleaning, unplug the power plug with the lid open, unscrew the rotor using the rotor key supplied and clean it
separately. Use a mild cleaning agent for cleaning the accessible surfaces of the device. Choose disinfection methods that
correspond to the current legal regulations and guidelines for your area of application. Use, for example, alcohol (ethanol,
isopropanol) or alcohol-based disinfectants.
Do not allow any liquid to get into the gap at the motor shaft outlet. For this reason, the rotor chamber should be cleaned
only with a damp cloth.
You should also consult your laboratory safety officer with regard to a suitable method of cleaning and disinfecting. Before
any cleaning or disinfecting method other than that recommended by the manufacturer is used, please check with
Eppendorf that the intended method will not damage the device or its accessories. In order to ensure long-term, reliable
work with your centrifuge, please note that aggressive chemicals may damage the rotor and the chamber. Check your
device once a month for corrosion and damage.
The rubber seals in the rotor chamber should be rinsed off thoroughly with water and lubricated with glycerin or talc after
every clean to prevent them becoming brittle.
The rotors, buckets, tube holders and adapters should be cleaned once a month or when necessary with a neutral
cleaning agent to prevent residues of the material being centrifuged from changing the properties of the centrifuge and its
accessories. The rotor must be taken off for this.
Never place components in disinfectants or cleaning agents which contain sodium hypochlorite/chlorine or are oxidants.
This will cause the material to change. Disinfection with glutaraldehyde solution is possible. We recommend Cidex
®
activated glutaraldehyde solution. The plastic adapters and rubber plates are dishwasher safe.
Check the tube holders and buckets for residues and corrosion. For thorough cleaning, remove the rubber plates from tube
holders and buckets and clean all parts separately.
Then refit the rotor and bolt it into place with the supplied rotor key. Check the rotor, tube holders and buckets once a
month for mechanical damage.
All rotors, buckets, adapters, caps and tube holders can be autoclaved (121 °C, 20 min).
The aerosol-tight cap, including silicon sealing ring, rubber mats and rectangular bucket adapters are subject to normal
wear and must be replaced when a visual inspection reveals wear.
Do not unbolt the rectangular bucket adapters from each other.
On the swing-bucket rotor make sure, in particular, that the pegs and grooves of the buckets are free of dirt. They should
be lightly lubricated with pivot grease (provided with each swing-bucket rotor) so the buckets can swing freely.
The aerosol-tight buckets must not be stored with their caps sealed!
Clean condensation water and ice buildup regularly from the rotor chamber (by defrosting), using a soft, absorbent towel.
Regularly empty and clean the condensation water collector. Remove this from the left. Please clean the condensation
water drain regularly.
