Accident Prevention
WARNING If a hazardious situation occurs, turn off the power supply to the centrifuge
and leave the area immediately.
WARNING If the centrifuge is used in a manner nor specified in this manual, the
protection provided by the centrifuge may be impaired.
Prerequisite for the safe operation of the Sorvall Medilite is a work environment in
compliance with standards, directives and trade association safety regulations and proper
instruction of the user.
The safety regulations contain the following basic recommendations:
•Maintain a radius of at least 30 cm around the centrifuge.
•Implementation of special measures which ensure that no one can approach the
centrifuge for longer than absolutely necessary while it is running.
•The mains plug must be freely accessible at all times. Pull out the power supply plug or
disconnect the power supply in an emergency.
Remaining risk: Inproper use can cause damages, contamincation, and inju-
ries with fatal consequences.

P Precautions
Thermo Scientific Medilite Microcentrifuges iv
Precautions
In order to ensure safe operation of the Sorvall Medilite, the following general safety
regulations must be followed:
•The centrifuge should be operated by trained specialists only.
•The centrifuge is to be used for its intended use only.
•While handling centrifuge, rotor, and samples you must wear laboratory clothing (e.g.
gloves).
•Plug the centrifuge only into sockets which have been properly grounded.
•Do not move the centrifuge while it is running.
•Do not lean on the centrifuge.
•Use only rotors and accessories for this centrifuge which have been approved by Thermo
Fisher Scientific. Exceptions to this rule are commercially available glass or plastic
centrifuge tubes, provided they have been approved for the speed or the RCF value of
the rotor.
•Do not use rotors which show any signs of cracks.
•Use only with rotors which have been properly installed. Follow the instructions in
section “Rotor Installation” on page 4-2.
•Use only with rotors which have been loaded properly.
•Never overload the rotor.
•Never open the door until the rotor has come to a complete stop.
•Never use the centrifuge if parts of it are damaged or missing.
•Do not touch the electronic components of the centrifuge or alter any electronic or
mechanical components.
•Please observe the safety instructions.
Please pay particular attention to the following aspects:
•Location: well-ventilated environment
•Place the centrifuge on a clean, dry surface, to make certain that the suction feet at the
bottom grip the surface firmly.
•Especially when working with corrosive samples (salt solutions, acids, bases), the
accessory parts and rotor chamber have to be cleaned carefully.
•Always balance the samples.

PPrecautions
vMedilite Microcentrifuges Thermo Scientific
Centrifuging hazardous substances:
•Do not centrifuge explosive or flammable materials or substances which could react
violently with one another.
•The centrifuge is neither inert nor protected against explosion. Never use the centrifuge
in an explosion-prone environment.
•Do not centrifuge inflammable substances.
•Do not centrifuge toxic or radioactive materials or any pathogenic micro-organisms
without suitable safety precautions.
When centrifuging microbiological samples from the Risk Group II (according to the
Biosafety Manual" of the World Health Organization (WHO)), aerosol-tight biological
seals have to be used.
For materials in a higher risk group, extra safety measures have to be taken.
•If toxins or pathogenic substances have gotten into the centrifuge or its parts,
appropriate disinfection measures have to be taken (see “Disinfection” on page 5-3).
•Highly corrosive substances which can cause material damage and impair the
mechanical stability of the rotor, should only be centrifuged in corresponding protective
tubes.
Remaining risk: Inproper use can cause damages, contamincation, and inju-
ries with fatal consequences.
Remaining risk: Inproper use can cause damages, contamincation, and inju-
ries with fatal consequences.
