5-4. Preparing Sample Tubes
WARNING
Do not use the MX-307, 207 and 107 to
centrifuge flammable or explosive samples.
● Failure to do so may damage the instrument,
thereby resulting in death or serious injury to
laboratory personnel. The MX-307, 207 and 107
are not an explosion-proof model.
Do not use the MX-307, 207 and 107 to
centrifuge infectious samples.
● Failure to do so may cause serious or potentially
lethal diseases to laboratory personnel. The
MX-307, 207 and 107 are not abiohazard safety
model.
CAUTION
Do not use any damaged, deformed, or
corroded tube.
●
Otherwise, it may be broken during spinning,
resulting in an unbalanced load and causing the
rotor to fall off.
Ensure that the maximum allowable RCF of
the tube.
● Failure to do so may break the tube and cause the
rotor to fall off during spinning.
Do not exceed the actual maximum achieved sample capacity for the
centrifuge tube.
● An excessive capacity may cause the sample to spill during spinning and much
less capacity may cause deformation of the tube, resulting in an unbalanced
load. It may apply excessive force to the motor shaft, thereby causing the rotor
to fall off.
When the mass density of the sample exceeds 1.2 g/cm
3
, the revised
maximum allowable speed of the rotor should be calculated
respectively.
●
An excessive speed may damage the rotor, bucket or rack, thereby causing the
rotor to fall off.
