• Rotor installation: verify that the rotor is locked in position before
use.
• Cleaning of the accessories and of the rotor chamber is particularly
necessary when corrosive products are present in the samples
(saline, acids, bases).
• Load balancing.
IF ANY DANGEROUS EVENT OCCURS, KEEP YOURSELF FAR
AWAY FROM THE INSTRUMENT AND SWITCH OFF THE
MAIN POWER SOURCE
A view port located on the lid allows the measurement of the actual
speed by a phototachometer.
Once a year, check for correct r.p.m. readout and speed control setting
which should be within 100 r.p.m. of the actual.
The T3/G3 series of centrifuges and their associated rotors offer a high
level of RCF performance. In some cases the maximum possible RCF
will exceed the one sustainable by the sample container.
The rotor RCF performance displayed is the maximum available in the
rotor pockets. Depending on the sample containers or on other
application needs, the maximum RCF which must be used is to be
determined by the operator.
The centrifuge is not explosion proof.
Using this centrifuge with explosive samples is entirely at the user’s own
risk. Do not under any circumstances use the centrifuge in an explosive
environment.

Due to the action of the turbulence created in the bowl, a centrifuge is
an aerosol generator.
A ventilated centrifuge (like the T3/G3 exhausts, into the room, air
which has passed through its bowl.
Thus the risk of the spread of aerosols is significant in a ventilated
centrifuge.
In the case of samples presenting a biological or chemical risk, the
operator must take suitable precautions to prevent or reduce this risk.
