GENERAL INFORMATION 7
1. IMPORTANT INFORMATION
The following general instructions, and the precautions regarding the
prevention of corrosion in rotors and accessories, as described under
MAINTENANCE, must be noted and carefully observed.
The maximum load should always be checked before commencing any operation. If
the sample has a relative density greater than 1.2, the maximum permissible speed of
the rotor should be calculated as given in this publication, and applied.
Any liquid spilt in the centrifuge should be removed immediately because corrosion is
a major cause of failure in centrifuges. Where particularly corrosive solutions are used,
the samples should be placed in sealed containers and all necessary precautions
observed. The following list gives some examples of corrosive liquids used, particularly
in the biochemical field:
Phenol/cresol/water, chloroform/isoamyl alcohol, salt solutions (especially ammonium
sulphate), solutions of ammonium hydroxide and solutions of acids such as
hydrochloric, trichloroacetic and perchloric acids.
It should be noted that many other substances used in different fields are often equally
corrosive. Users should always check whether or not a substance being used is
corrosive in order to take suitable precautions.
NOTE: The following materials are prohibited:
Flammable or explosive materials
Materials which chemically interact vigorously
The load must be distributed symmetrically round the rotating assembly so that it is
evenly balanced and complies with the manufacturer's instructions in this respect.
After use the sleeves and adaptors in centrifuge rotors should be removed to allow
thorough cleaning of rotors and accessories and so prevent corrosion.
Special care is necessary when using infective material in centrifuges. Containers,
when used with such materials, should be closed while being centrifuged and sterilised
immediately after use, using non-corrosive means.
NOTE: Sealed containers and related components are intended to be part of
biosafety systems such as are specified in international and national
biosafety guide lines, and cannot be relied on as the only means of safeguarding
workers and the environment when handling pathogenic
micro-organisms.
Care should be taken to preserve intact, sets of accessories which have been supplied
as sets, in which all the members possess closely similar weights.
It is advisable to have the centrifuge checked by a competent engineer, preferably the
manufacturer's representative, at least every six months.
Carbon brushes, whilst being of the highest quality obtainable are expressly excluded
from the guarantee. A spare set is included in the accessory pack. The method of
replacement is detailed in section 6.7 of this manual.

GENERAL DESCRIPTION 8
2. GENERAL DESCRIPTION
The Centaur 2 centrifuge is CE marked in line with required European Directives
for Electromagnetic and Low Voltage Compatibility, see “Declaration of
Conformity” for EC Directive/standard used.
120v units designed for CSA approval to the following standards:
CAN/CSA C22.2 No. 1010.1-92
CAN/CSA C22.2 No. 1010.2.020-94
INDEPENDENT SPEED SENSING - 120 volt Machines only
To comply with certain USA standards the 120 volt machines are fitted with a
small window in the cover. This permits independent speed check directly from the
rotor with use of an optically coupled tachometer.

GENERAL DESCRIPTION 9
2.1 Controls And Indicators
Figure 1.
Control Panel of the Centaur 2 Centrifuge
1. The Power On rocker switch, when on (switch illuminated) connects power
through to various circuits and components within the centrifuge.
2. The Fuse Holder carries a 20mm long, 5 Amp glass cartridge fuse. It is easily
removable.
3. The Timer control allows a run period up to 30 minutes-selected by turning the
knob clockwise. When the time selected has run out, the rotor will automatically
run down to a stop. If required, the knob may be returned (anti-clockwise) to a
lesser time or to the Off position at will. It cannot be turned anti-clockwise
between the 'Hold' and '30' 'positions. The Hold position switches the centrifuge
for continuous running until manually reset to Off.
4. The Rev/min indicator is a digital display giving continuous read-out of the
rotational speed of the rotor, rounded off to the nearest hundred rev/min, e.g.
2500, 3200.
5. The Speed control allows selection of any speed between 300 rev/min and the
maximum allowed for the rotor in use (see section 4.5 Rotors And Accessories
Tables) as indicated on the Rev/min digital display.
6. The Imbalance indicator lamp (Red) when on, gives warning that the rotor is
misloaded to a marked degree. In this event, drive to the rotor will cease and
the rotor will run down to a stop. Loading and balance must be checked and
corrected before re-starting the centrifuge.
7. The Lid Unlocked indicator lamp (Amber) when on, indicates that the rotor is
at a standstill and the lid may be opened safely. When the rotor is spinning the
lamp remains off and the lid is locked.

GENERAL DESCRIPTION 10
2.2 Centrifuge Bowl
The centrifuge bowl is easily removable for cleaning or disinfection purposes see
section 6 (Maintenance).
2.3 Opening Lid Manually
An electrical interlock prevents the lid being opened while the rotor is turning, or
when the power is disconnected. If access to the rotor is required during a power
failure, insert the Lid Lock Release Key (supplied with accessories) to its fullest
extent, into the small hole on the top of the lid, near the front; move the point
towards the rear against a slight spring pressure to actuate the lid lock
mechanism. Press the lid actuator to the right and open the lid.
The lid is friction-controlled, to remain open at any intermediate position desired.
