CAUTION
Do not move the MX-307, 207 and 107
with a rotor being mounted.
Otherwise, the motor shaft may bend,
thereby causing the rotor to fall off during
spinning.
Ensure that there is no damage or
foreign material on the motor shaft.
Otherwise, the rotor cannot be mounted
properly on the motor shaft, thereby
causing the rotor to fall off during spinning.
Ensure that there is no damage,
deformation or corrosion in rotors
and racks.
Otherwise, the rotor cannot be mounted
properly on the motor shaft, thereby
causing the rotor to fall off during spinning.
Ensure that there is no foreign
material in the rotor or in the
chamber before operating the MX-
307, 207 and 107.
If any, it may break a sample during
spinning and its broken pieces may scatter,
resulting in a serious accident. Or an
unbalanced load may occur, thereby
causing the rotor to fall off.
Ensure that the rotor is installed
securely on the motor shaft.
Otherwise, the rotor may come off during
spinning.
Do not use any damaged, deformed,
or corroded rotors, buckets, racks,
adapters or tubes.
Failure to do so may cause an unbalanced
load and may allow the rotor to drop off
during spinning.
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 sample to
spill during spinning and result 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/cm3, 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 during spinning.
Load the rotor symmetrically around
the motor shaft. Opposing adapters,
tubes and samples should be of the
same type and tubes should be filled
equally.
Otherwise, it may cause an unbalanced
load and apply excessive force to the rotor,
thereby causing the rotor to fall off.
Ensure that no water drop or foreign
material is inside the tube hole.
Otherwise, unbalanced load may occur,
applying excessive force to the motor shaft,
thereby causing the rotor to fall off.
Ensure that the load of the tube or
sample is appropriately balanced.
Otherwise, unbalanced load may occur,
applying excessive force to the motor shaft,
thereby causing the rotor to fall off.
Be sure to attach the rotor lid to the
rotor if it is provided and make sure
it is surely secured and closed.
Otherwise, it may cause the rotor to fall off
during spinning.

CAUTION
Never run the MX-307, 207 and 107
with the rack sticking out the rotor.
Otherwise, the rack may come off during
spinning.
Check the type of the rotor and rack
before use to ensure the correct
combination is set.
Otherwise, it may cause damage to the
instrument. Please refer to the table of
“Rotor Rack Compatibility for Rack-in-
Rotor” in this Operator's Manual for proper
combination.
Ensure that the same type of buckets
are correctly mounted into all four
positions on the swing-out rotor.
Otherwise, it may apply excessive force to
the rotor, thereby causing the damage to the
rotor.
Ensure that all buckets on the swing-
out rotor are allowed to move freely
after loading sample tubes.
Otherwise, unbalanced load may occur
during spinning, applying excessive force
to the motor shaft, thereby causing the rotor
to fall off.
Do not exceed the maximum
allowable RCF of the tube.
Failure to do so may break the tube and
cause the rotor to fall off during spinning.
When the mass density of the sample
exceeds 1.2 g/cm3, do not centrifuge
at speed exceeding the maximum
allowable speed of the rotor which is
respectively calculated.
An excessive speed may damage the rotor,
bucket or rack, thereby causing the rotor to
fall off during spinning.
Avoid touching sharp edges on the
heat exchanger.
Otherwise, it may cause an injury.

1-3. Expected Lifetime of Rotors and Buckets in Years or Cycles
WARNING
Do not use rotors or buckets beyond their expected lifetime in years or
cycles.
●Failure to do so may result in the rotor or bucket breaking during spinning.
The table below shows the expected lifetime of rotors and buckets for use in the MX-307, 207
and 107 in terms of years or cycles. When the rotor or bucket reaches the end of its expected
lifetime in years or cycles, stop its operation immediately and contact your dealer or local TOMY
representative. Operating environment can create abnormalities such as damage, deformation
or corrosion, which may reduce the lifetime of the rotor or bucket. If any signs of damage,
deformation or corrosion are present, stop using the rotor or bucket and contact your dealer or
local TOMY representative.
♦Expected lifetime in years:When the number of years listed in the table below has passed after delivery.
※Information on the lifetime is engraved on the rotor and bucket marked with an asterisk in the table.
Engraved mark example:[ Exp.08/2025 ] … It indicates the expiration date is August, 2025.
♦Expected lifetime in cycles:When the number of run cycles has reached the number of cycles listed in
the table below.
※When the rotor or bucket approaches its run cycle limit, error messages appear on the display.
Please refer to “9-2. Error Code Table.”

2. GENERAL INFORMATION
2-1. Operating Principles
MX-307, 207 and 107 High Speed Refrigerated Micro Centrifuge are a device which separates a
sample solute from a solvent by way of the centrifugal force resulting from its rotation.
When the MX-307, 207 or 107 starts operation, the motor begins to drive and accelerate the
rotor, while the timer starts simultaneously. When the centrifuge reaches its set rotation speed,
it maintains the speed until the set operation time ends. The separation of samples is attained
by introducing centrifugal force generated by this rotor rotation. When the preset time elapses,
the motor starts deceleration. When the rotor stops rotation, the centrifuge emits a signal tone
and lights up the “STOP” lamp to indicate the centrifugation is finished.
While the centrifuge is powered on, it maintains the set temperature by cooling down inside
chamber using the refrigerator.
When an abnormality occurs in the centrifuge, it may return to a safer operation status and a
signal tone will sound and an error code will display.
