6 Preparation of Rotor
WARNING:
•This centrifuge is not explosion-proof. Never use explosive or flammable samples.
•There are restriction on the usage of biological samples and radioactive
substances that require biological isolation such as pathogens and recombinant DNA
for safety purposes. User must prepare necessary safety measures before treating with
samples containing such substances.
1) Prepare the sample
2) Put the sample into tubes or bottles
CAUTION: Sample may leak from the gap between the bottle and its cap if the
bottle is fully filled up.
◼Do not exceed the capacity specified in the instruction manual.
3) Balance the centrifuge tubes or bottles
CAUTION: There are some cases where samples of different composition due in
different precipitation levels by centrifugation even if they are equal in volume, and such
operation may increase the level of imbalance. Properly arrange the tubes or bottles so
that the same sample is placed symmetrically.
◼See Table 6.1 for imbalance tolerance of each rotor.
◼Recommend that you use this centrifuge in a well-balanced condition to prolong its
life expectancy.
◼Never intentionally run the centrifuge under unbalanced condition even though the
allowable imbalance tolerance is not exceeded.
4) Inspect the rotor
CAUTION:
⚫If any abnormality such as corrosion or scratches is found, stop using the rotor and
contact our service representative.
⚫Only use the rotors we recommended.
◼Check whether the rotor have corrosion or scratch before using.
5) Set balanced tubes or bottles symmetrically on the rotor
CAUTION: Make sure that the cover is put on the rotor and fixed securely.
Otherwise, the rotor or its cover may be dropped off while the instrument is running.
That might damage the centrifuge or the rotor.
