Benchtop Low Speed Centrifuge BCFL-203

We appreciate your business with Biolab. To prevent any potential accident, please operate
centrifuges according to the following safety protocol.
1. Unplug the main power cord, when performing maintenance or when centrifuge is
expected not being used for a long period of time.
2. Load the rotor with samples arranged symmetrically. Opposing tubes must be of equal
weight. If necessary, use "water blank" tubes to balance sample tubes of unequal weigh. Do
not conclude that tubes are balanced by sight over volume. Use the pan balance provided in
the centrifuge room for balancing tubes in rotors for the centrifuge.
3. Never excede the maximum speed posted for the rotor!
4. Never use the rotor that appears damaged (e.g. O-rings missing, scratched, corroded,
cracked).

2 Unpacking
Please check whether there are serious damages on the package as soon as you received the
centrifuge, if so, please contact us directly, if not, please unpacking the package, take out the
instruction manual, checking the components and accessories. If you found something
missing, please tell us.
(1)The centrifuge should be installed on a rigid, even surface.
(2)Electrical source should be 22 V/11 V Single phase, with independent earth line, never
replace the earth line with the neutral line.
(3)No shock wave-generating items, nor corrosive gas in the nearby environment
(4)Relative humidity of environment: 85%
(5)To guarantee sufficient ventilation, please ensure that the centrifuge has at least 15 cm free
space on all sides, including the rear.

(7).Installation of the rotor:(Pay attention to this part carefully)

Rotating sleeve expension screw with the wrench from closewise with 1-2 circles, then put the
rotor. Check the sleeve expension screw to make sure it is very loose before putting into rotor.
That is because only when the sleeve expension screw is very loose, the rotor can be fully
installed down to the shaft which is correctly installed. If the rotor is installed fully: move the
rotor up and down from the shaft, you could hear “bang bang...” sound. If you find the sleeve
expension screw is tight and the rotor can not be installed down fully ,rotating with the
wrench from anticlockwise 3-4 circles to loose the screw and move the rotor up and down to
check, if you can hear” bang bang”,it is correct, if not, continue to loose the screw till the rotor
can be fully installed down to the shaft. Only after the rotor is fully installed down to the shaft,
then you can tighten the rotor.

3 Operation
(1)Power on
Power switch is located on the right bottom corner of control panel. Turn it to “On” position,
the power indicator will turn red.
(2)Lid release
Press on “Open” button, the lid will “click” to open, push the lid upward until it open
completely. Spring level will help to open the lid.
(3)Proper loading of the rotor
Check the rotor before loading. Never use rotors showing signs of cracking or corrosion,
never use expired rotors.
Load the rotor to the central adapter located on the axle of electrical motor, and tighten the
screw on it.
Fill the tubes equally by eye (about 75% of the total volume), balance the tubes by scale. The
difference in weight between the tubes should not exceed 2 grams.
Load the tubes symmetrically.
(4)Closing the lid
After the rotor has been properly loaded, close the centrifuge lid. If “E-1” appears on the
“Speed screen”, it means the lid is not shut properly.
(5) Set the parameters
