1-2-3 Safety devices
(1) Protection of rotor chamber
Should the rotor spinning at high speed fails (or comes off the drive shaft), the safety of the operator is
ensured by the thick protector (Protection steel tube) enclosing the cooling bowl (Fig. 1-2-2).
(2) Imbalance detector
If during operation the vibration of the rotor becomes excessive due to serious imbalance or improper
bucket setting, the imbalance detector detects the situation and decelerates the rotor immediately.
However, the ultracentrifuge is designed to tolerate imbalance associated with visual balancing-it is
equipped with an imbalance tolerant drive. (For more information on the balancing of rotors, see
Section 2-1-2 "Preparing tubes/bottles and rotor".)
(3) Door lock system
The chamber door automatically locks for safety while the rotor is spinning. When the power supply is
off, the door remains locked. The door can only be opened and closed when the rotor is at rest and the
rotor chamber is vented. To open the door in the event of a power failure, see Section 2-5 "Emergency
recovery from power failure".
(4) Overspeed detector
This ultracentrifuge incorporates a detector designed to prevent the rotor from spinning at a speed
exceeding the maximum allowable speed.
Two independent microprocessors (CPUs) check the rotor for overspeed, thus increasing safety further
(dual CPU overspeed preventive mechanism).
The first CPU detects overspeed and performs control and display. Should the rotor be set to a speed
exceeding the permissible speed, this CPU detects an alarm massage of “SPEED” from the low speed
range (about 2,000 rpm), and stops the rotor.
(But this second CPU does not display an alarm message, because it is not connected to the display-
performing CPU. Should the alarm device be activated, pressing START button will not run the
instrument. Turn off the POWER switch, wait for several minutes, turn the POWER switch on again,
then pressing START button.)

WARNING：1. This centrifuge is not explosion-proof. Never use explosive or flammable samples, or
materials that chemically react vigorously. Do not centrifuge such materials in this
instrument nor handle or store them near the instrument.
2. Take all necessary safety measures before using samples that are toxic or radioactive,
or blood samples that are pathogenic or infectious. You use such samples at your
own responsibility.
CAUTION ：Do not place containers holding liquid in the rotor chamber, on the centrifuge, or near the
centrifuge. If spilt, liquid might get into the instrument and damage electrical and
mechanical components.

2-1-2 Preparing tubes/bottles and rotor
The CS150NX allow you to balance, by eye, tubes or bottles containing a sample solution and then centrifuge
them. Make sure that the approximate difference between meniscus levels of sample solution in tubes or
bottles is within 5 mm (See fig. 2-1-2).
Fig. 2-1-2 Balancing tubes/bottles containing a sample solution
CAUTION ：Do not run the ultracentrifuge in an extremely imbalance condition. This might cause a
mechanical failure. When balancing tubes or bottles by eye, alarm message
“IMBALANCE” might appear. Balance tubes or bottles more accurately again if alarm
message “IMBALANCE” appears.
Depending on the type of tube or rotor combined with this machine, an excessively low liquid level may limit
the speed or crush the tube.
• When sealed tubes are used, fill the tubes with liquid to the full level.
CAUTION ：1. Before using a rotor, read the rotor instruction manual carefully.
2. Do not use any corroded, scratched, cracked, or otherwise damaged rotor or bucket.
Before operation, always check if there is no corrosion and damage on the rotor
surface.
3. Before running a swing rotor, make sure that each bucket is hooked on a pin securely.
Poor setting might seriously damage the instrument. Even though all of them are not
used, make sure to install all buckets at any time. Make sure that all the rotor buckets
are of the same type.
4. Some tubes and adapters are inapplicable at the maximum speed of the rotor.
Refer to the rotor instruction manual carefully.
5. The S58A rotor, S55A rotor, and S50A rotor can handle sample whose mean density is
1.2 g/ml or less.
Do not rotate this rotor at its maximum speed when using a sample whose mean
density is over 1.2 g/ml. Refer to the rotor instruction manual (Part No. S999276) for
how to limit the maximum speed when using a sample whose mean density is
over 1.2 g/ml.
