Preface
Before starting to use the centrifuge, read through this
instruction manual carefully and follow the instructions.
The information contained in this instruction manual is the
property of Fisher Scientific; it is forbidden to copy or pass on
this information without explicit approval.
Failure to follow the instructions and safety information in this
instruction manual will result in the expiration of the sellers
warranty.
Scope of Supply
If any parts are missing, please contact your nearest Fisher
Scientific representative.
Intended Use
• This centrifuge is designed to separate sample mixtures
of different densities like chemicals, environmental
samples and other non-human body samples.
Accident Prevention
Prerequisite for the safe operation of the Centrifuge GT 2/2R
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.
Precautions
In order to ensure safe operation of the Centrifuge GT 2/2R,
the following general safety regulations must be followed:
• Do not manipulate the safety devices.
• The centrifuge should be operated by trained specialists
only.
• The centrifuge is to be used for its intended use only.
• 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 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 corrosion
and/or cracks.
• Do not touch the mechanical components of the rotor
and do not make any changes to the mechanical
components.
• Use only with rotors which have been properly installed.
Follow the instructions on the Auto-Lock in section Rotor
Installation.
• Use only with rotors which have been loaded properly.
Follow the instructions given in the rotor manual.
• Never overload the rotor. Follow the instructions given in
the rotor manual.
• Never start the centrifuge when the lid is open.
• Never open the lid until the rotor has come to a complete
stop and this has been confirmed in the display.
• The lid emergency release may be used in emergencies
only to recover the samples from the centrifuge, e.g.
during a power failure (Refer to Mechanical Emergency
Door Release).
• Never use the centrifuge if parts of its cover panels are
damaged or missing.
• Do not touch the electronic components of the centrifuge
or alter any electronic or mechanical components.
• Observe the safety instructions.
Pay particular attention to the following aspects:

2 | Centrifuge GT 2/2R
• Location: well-ventilated environment, set-up on a level
and rigid surface with adequate load-bearing capacity.
• Rotor installation: make sure the rotor is locked properly
into place before operating the centrifuge.
• Especially when working with corrosive samples (salt
solutions, acids, bases), the accessory parts and vessel
have to be cleaned carefully.
• Always balance the samples.
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 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 Bio-safety 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 (Refer to section Disinfection).
• Highly corrosive substances which can cause material
damage and impair the mechanical stability of the rotor,
should only be centrifuged in corresponding protective
tubes.
IF A HAZARDOUS SITUATION OCCURS, TURN OFF
THE POWER SUPPLY TO THE CENTRIFUGE AND
LEAVE THE AREA IMMEDIATELY.
This symbol refers to general hazards.
CAUTION: means that material damage could
occur.
WARNING: means that injuries or material
damage or contamination could occur.
This symbol refers to biological hazards.
Observe the information contained in the
instruction manual to keep yourself and your
environment safe.

Centrifuge GT 2/2R Introduction and Description | 3
Introduction and Description
Characteristics
Several rotors with a wide range of tubes can be used.
The set speed is reached within seconds. The maintenance-
free induction motor ensures quiet and low-vibration
operation even at high speeds, and guarantees a very long
lifetime.
The user-friendly control panel makes it easy to pre-set the
speed, RCF value, running time, temperature, and running
profile (acceleration and braking curves). You can choose
between the display of speed and RCF or the entry mode.
These settings can be changed even while the centrifuge is
running.
With the help of the PULSE key , you can also centrifuge
a sample for just a few seconds, if called for.
The Centrifuge GT 2/2R is equipped with various safety
features:
• The housing and rotor chamber consist of steel plate, the
interior of armour steel, while the front panel is made of
high-impact resistant plastic.
• The lid is equipped with a view port and a lock.
• The lid of the centrifuge can only be opened while the
centrifuge is switched on and the rotor has come to a
complete stop. The centrifuge cannot be started until the
lid has been closed properly.
• The integrated rotor detection systems ensures that no
inadmissible speed settings can be preselected.
• Electronic imbalance recognition
• Lid emergency release: For emergencies only, e.g. during
power failures (Refer to the section Mechanical
Emergency Door Release)
