6 Preparation (Rotor)
WARNING:
This centrifuge and the rotor are 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 that is specified in the instruction manual.
3) Balance the centrifuge tubes or bottles
CAUTION:
The samples with different composition but same volume have different
sedimentation during centrifugation and will cause imbalance. Due to this, the sample
with same composition should be placed symmetrically.
See Table 6.1 or the rotor specification for imbalance tolerance of each rotor.
Although this centrifuge can accept eye balancing sample, we recommend that the
sample are well-balanced to prolong its service life.
Never intentionally run the centrifuge under unbalanced condition even though the
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 Dynamica service representative.
Other brand or type of rotor is forbidden on the instrument.
Check the rotor and the buckets for corrosion or scratch before use.
Check whether the swinging bucket rotor swings smoothly by slightly spinning the
rotor manually. Perform periodic maintenance on the rotor.
5) Set balanced tubes or bottles symmetrically on the rotor or rotor frame
