(Ⅱ) ROTOR AND ACCESSORY
1. Centrifugal force calculation: Use its speed and radius to calculate force as following
formula.
RCF= (rpm)
R: radius (cm)
RCF: Relative Centrifugal Force ( xg )
2. Acceptable speed and load:
Please refer to the form (Ⅱ-4) to see the max. speed each model of rotor and tube carrier
can be load. The load weight including: rotor, tube carrier, washer, samples, and so on.
3. Sterilizing and cleaning rotor:
Rotor is made of stainless steel or steel or aluminum with high density coating and highly
resistant to corrosion, but not fit to alkaline and strong acid substance.
Note: Don’t heat the rotor to a high temperature (100℃) to clean or sterilize it.

(Ⅲ) INSTALLATION
1. When you take out centrifuge from carton, please check if there is any scratch, press
trace and damage on knob or not. If yes, please contact local dealer immediately.
2. Please install the centrifuge on a horizontal and stable tab le o r bench. If not, it will
affect anti-vibration efficiency.
3. Please use power voltage as following range. To avoid electric shock please make sure
to connect ground wire to the ground terminal.
Power voltage Acceptable voltage range
100V / 110V 90V ~ 110V / 99V ~ 121V
220V / 240V 198V ~ 242V / 216V ~ 264V
4. Keep it away from dusty and moist working place.
5. Avoid the same power source with the large electric consumption machine at same time.
6. After dismantle or clean rotor, please must screw it tightly.

(Ⅳ) OPERATION
1. Tube & Sample Setting
(1) The tubes in use must be placed in even number such as 2, 4, 6, 8. Glass tube must be
placed in carrier completely which are positioned symmetrically toward rotor center.
When you use tubes in odd number, it is necessary to put same volume of water in a
separate tube and then place such tubes into carrier for dummy use.
(2) Please consider the speed and centrifugal force the tubes can bear or not, or it will
cause the tubes easy broken from rotation.
(3) Please note tube length, if it is too long than the top of tube will hit the rotor and break.
If you have to put longer tubes in angle rotor, please place an interval between tubes.
(4) Adapter is available for tube’s diameter much smaller than carrier’s, it can prevent tube
broken from rotation.
c correct ² incorrect Adapter
50cc→15cc 15cc→6cc
Caution:
a. Adapter should be placed into tube carrier properly, if it is slanted, then tube is
difficult to take out from carrier. If glass tube is broken or if rotor elapsed over
one year, then rotor needs to be renewed. Damaged rotor or rotor containing
broken glass will cause glass tube broken easily.
b. Carrier should be placed onto rotor properly, if not, it will be imbalanced and
destroy centrifuge, meanwhile to check if carriers swing normally by hand first.
c. Stainless steel tube carrier can be used for acidity and alkalinity tube
samples. (please purchase separately)

2. Door Lock & Cover
r
(1) Please close cover tightly, otherwise rotor can not rotate, cover can not be opened
during rotation.
(2) Plug in the socket and switch it on, then press【Manual safe button】to open cover.

4. Operation Procedure:
(1) Turn the speed to be “0” then plug in the centrifuge.
(2) Press【Manual Safe Button】and cover can be opened.
(3) Place sample into carrier.
(4) Close cover.
(5) Adjust timer to the desired time.
(6) Turn the speed to the required rpm, rotor begins to rotate and goes up to desired speed.
(7) Time is up, then press【Manual Safe Button】to open the cover and power cut off at the
same time.
Caution:
1. Please don’t open cover during rotation.
2. During rotation, please don’t exceed the max. speed of the centrifuge (refer to page 3) and
don’t place substandard rotor.
3. The centrifuge is without anti-explosion, so please don’t explosive material.

1. Checking before and after operation
* Check to see if there is any material or water inside chamber and keep it clean.
* Check to see if the rotor is loose or not; if yes, after screw it then use it again.
* Check if carriers can swing smoothly, if not, please clean the rotor.
* Check if carrier is hung well, if not, then stop it and contact with local distributor.
* Check if cover is properly close and screws fixed or not; if not, then stop it and contact
with local distributor.
* Check if the ground wire is connected well, lamps and switch are available.
2. Daily checking:
Clean stain in chamber, check if there is any scratch, deformation, and corrosion on rotor
or carrier.
If yes, please contact local dealer for further checking.
3. Yearly checking:
Check if “rotor fixing nut” is loose or not; and the indication value of speed meter can
match real value or not , if not , please contact local dealer.
4. Cleaning:
When sample is split over rotor or carrier, please use cloth with little detergent to wipe
and dry it. When sterilization is made on rotor or carrier, do not heat it to a temperature
exceeding 100℃.
