Definition
：
g Force
The measurement for samples undergoing the stress of
acceleration in a centrifuge.
RCF
（
Relative Centrifugal Force
）
RCF is the centrifugal force that the samples undergoes which
relies on the speed of rotation
（
N
）
in rpm and the rotating radius
(cm)
（
R
）
. The rotating radius is measured from the center axis of
rotor to the extreme end of the centrifuge tubes.
Formula:RCF = 11.18 x R x ( N / 1000)²
A-0815: Ø 21.1cm;
A-1215:Ø 22.7cm

TUBES
Round bottom
：
Have a uniform wall thickness and provides a better fit in a rotor
than conical bottom tubes. Round tubes withstand higher
g-forces.
Conical bottom
：
Ideal for cell culturing and ammonium sulfate precipitations.
1. All centrifuges have come with the tube holders, in which a rubber
cushion is installed inside the tubes.
2. The tube adaptor is applied to the volume either 10ml or 15ml.
3. Do not place the cushion upside down or in a slant position.
4. Replace the cushion once the glass tube is broken.
5. Be sure the tube adaptors are placed into the rotor completely.
3

Grounding
This centrifuge is installed with a 3-pin electric cable. Be sure to well
connect the grounding wire to the terminal.
WARNING:
Do not connect the grounding pin to the following areas:
1. Gas piping or faucet
Explosion or fire may occur
2. Other wires of lighting
Electric shock or fire may occur
3. Other electrical applicants.

HOW TO INSTALL TESTING TUBES
The balance of rotor has been well calibrated in house thoroughly
before delivery, the user is again requested to install the testing tubes
in the correct way carefully prior to spinning this centrifuge as depicted
below:
1. Place the testing tubes into the tube adaptors diagonally and
symmetrically to balance the rotor. Please refer to the figure.
2. Place the testing tubes gathering on one single side will create
imbalance of rotor, which will possibly cause vibration of rotor.
3. If odd number of testing tube is used, supplement another dummy
tube to remedy the problem.
5

OPERATION:
-Check the specification label located on back of this equipment.
-Plug cord in a properly grounded outlet.
-Place the test tubes into the tube adaptors. Be sure to place the
tubes diagonally and symmetrically to keep the rotor balanced.
-Close the cover completely. NOTE, Locking latch is optional.
-Dial preset your desired time by turning the control knob for any
spin interval from 0 –60 minutes. This equipment is working by
timer-activated operation.
-When turn clockwise the timer, the pilot lamp will light up at the
same time, which indicates the power up.
-Adjust the control knob of speed regulator to bring speed to your
desired operation speed and centrifugal force.
-This centrifuge does not include the speed indicator, the reference
of speed and RCF is depicted below. Nevertheless, the user is
recommended to measure the speed by a hand held LCD
tachometer in order to achieve a correct speed and RCF.
-Speed and RCF varies slightly centrifuge to centrifuge.
-The bell rings and power will shut out automatically when the set
time has elapsed and the pilot lamp will distinguish simultaneously.
WARNING
：
-Do not open the lid only until the rotor has stopped completely.
-Do not stop the rotor by hand. There is possibility of personal injury.
-Gemmy will not ensure the responsibility if user violate the above
regulation.

Recalibration Procedure for Speed:
This centrifuge was initially set by its speed from 1000 –4500 rpm (or
4000 rpm for PLC-05) in house. Supposed that the min/max speed is
varied, the control can be recalibrated as depicted below:
1
、
Remove the bottom plate, switch power on by turning control knob
of timer. CAUTION:Electrical Shock
2
、
Turn knob of speed regulator to the extreme LOW position. Adjust
part of SVR P2/204 (for the low 1000 rpm control) right/left to get
the desired speed of 1000rpm.
3
、
To recalibrate the speed for 4000 or 4500rpm, turn speed regulator
to the extreme HIGH position, then adjust SVR (P1/104) right/left
slightly until it reaches 4000 or 4500 rpm.
4
、
The calibration of LOW or HIGH speed can influence each other;
thus the user is recommended to use the digital speed indicator
and measure the result of the recalibration. Repeat the above
procedure until the final speed indication meets your requirement.
5
、
Switch off the power and assemble the bottom plate.
6
、
Glue the parts of SVR (P1/104 and P2/204) after the speed
recalibration is finished. The transportation and vibration may
probably loosen the electronic parts and fasteners.
WARNING:
Electric shock and Personal injury. Always proceed with caution.
7

Speed and RCF Indication
The speed and RCF may be varied centrifuge to centrifuge caused by
its surrounding power consumption, which will result in a fluctuation of
speed. To assure an accurate rpm and its corresponding RCF, do not
place this equipment in the draft, sunlight or near a piece of equipment
that emits heat as well as Electromagnetic conduction emission.
1. Motor 67W (Average values from 5 random samplings)
2. Motor 90 W (Average values from 5 random samplings)
-Confidence interval: ± 95%
-User is recommended to measure speed and RCF by digital speed
indicator to achieve the practical values.

MAINTENANCE & SERVICING
：
To avoid electrical shock, always disconnect from power supply
prior to maintenance & Servicing.
People other than the qualified personnel or licensed engineers
are strictly prohibited from maintenance and servicing.
Always use a properly grounded electrical outlet of correct voltage
and current handling capacity.
Always inspect the rubber supports, replace the new one when
required in order to keep the balanced rotor.
Clean the chamber and rotor after use of this equipment.
Do not drop this equipment. Do not place this equipment upside
down.
The drive motor and linkage assembly do not require lubrication.
Always inspect the balance and speed at least once a month.
Inspect and replace the carbon brushes yearly or according to the
operation frequency or whenever it needs.
Use compressor to clean the dust inside the chamber that is
generated by the carbon brushes. Wearing the musk while
cleaning the dust to protect your respiratory system.
Carbon brushes are required from the origin of supplier. The
nature of carbon brushes, such as hardness and dimension, is
connection with the motor design. The carbon brushes out of the
origin of supplier will damage the motor.
The life of carbon brushes depends on the using frequency.
Always inspect the carbon brushes status and replace new ones
when required.
Inspect micro-switch and see if the function of automatic shutout
safety device is working.
A 5A.-fuse is equipped inside the circuit board to encounter the
abuse of voltage, so as to protect the electronic parts and motor
from burnout.
Inspect the speed indicator and see if its variable is accurate or not.
Calibrate the speed indicator if it can’t match the practical value.
