For your personal safety, please be sure to comply with
the following:
– The centrifuge 5702 must only be use for the specified applications (see Introduction). It
must not be operated in explosive atmospheres. Explosive or highly reactive substances
must not be centrifuged.
– When being moved from the cool room to a normal lab environment, the centrifuge must
either warm up for half an hour in the cool room first or it must warm up for at least 3 hours
in the lab before being connected to the supply system, in order to prevent damage by
condensation.
– The centrifuge must not be moved or knocked while in operation.
– Improperly installed or serviced centrifuges must not be operated. Repairs may only be
carried out by Service personnel authorized by Eppendorf. Use only original Eppendorf
spare parts and rotors.
– When handling toxic, radioactive liquids or pathogenic bacteria of risk group II (see World
Health Organization: Laboratory Biosafety Manual) comply with the relevant national
regulations. If such liquids are spilled in the rotor or rotor chamber, the centrifuge must be
thoroughly and professionally cleaned. Before using any cleaning or decontamination
method other than that set out in section 4, "Maintenance and cleaning", please consult
Eppendorf to ensure the intended method will not damage the device.
– Rotors must always be properly secured. The centrifuge may only be operated with the
rotor firmly tightened. For mechanical stability, all the places on the rotor must be fitted with
identical buckets.
– The rotor may only be loaded symmetrically. Opposing tubes should be of the same type
and be filled equally.
– Rotors showing clear signs of corrosion or mechanical damage must not be used. Check
the accessories regularly.
– Rotors are high-grade components which have to withstand extreme stresses and strains.
Aluminum rotors are largely protected from corrosion by the most common laboratory
chemicals by means of an anodized coating, though the protection is not unlimited. Protect
the rotors from mechanical damage. Even minor scratches or cracks can result in serious
internal material damage. Avoid weakening the rotors by the use of aggressive chemicals,
such as: strong and weak alkalis, strong acids, solutions of mercury, copper and other
heavy metal ions, chlorinated hydrocarbons, concentrated salt solutions and phenol. If the
rotor is contaminated by aggressive substances, clean it
immediately
with a
neutral
rinsing
solution.
– The material being centrifuged must not exceed a density of 1.2 g/ml at maximum rotation
speed. If the rotor is run for a lengthy period of time the sample tubes will become hot. Keep
within the limits specified by the tube manufacturers.
