0 Features and Applications
BCBL-207 Benchtop Low Speed Centrifuge (This machine below is short for this centrifuge
machine.), The series centrifuge is widely applied in biology, chemistry, medicine, agriculture
and forest science, food safety, blood station and clinical test.
This machine features good rigidity, high strength and corrosion proofing, owing to its high
material of steel and its surface with spurt models processing. Meanwhile, this machine
possesses the advantages of succinct structure, small volume, low noise, smooth temperature
rise, high efficiency, safe and reliable, and it is fit for the experimental analysis with fewer
samples and more separation steps.
This machine adopts the advanced technologies like microcomputer control, direct drive
brushless DC motor, TFT touch panel, mute mechatronics electronic lock and so on.
The features of this machine are as followed:
Step 1: Set up the rotor mode, the rotating speed and the needed time.
The vibration-absorption effect of this machine works very well by the application of its
special damper. This machine also has a self-balance function.
Step 2: Set up the rotor mode, the rotating speed and the needed time.
The special PWM-controlled speed control system assures its high control accuracy and its
fast acceleration and deceleration function, which provides different acceleration and
deceleration time to be freely chosen. To meet the requirement of labs, the brushless DC
motor also assures the operation of the machine in a quiet working state. The carbon brush
doesn’t need to be replaced, so there are no carbon pollutions.
Step 3: Set up the rotor mode, the rotating speed and the needed time.
This machine has a parameter-saving function, and it can calculate the RCF value
automatically.
Step 4: Set up the rotor mode, the rotating speed and the needed time.
There are many rotors with different levels. The tube frame can be replaced, and there are
many tubes, convenient to choose.
Step 5: Set up the rotor mode, the rotating speed and the needed time.
This machine has a protective function owing to its electronic lock. When its faceplate is
uncovered, the centrifuge machine cannot be operated.
This machine can be safely operated in the environment with the temperature within 5 to 40
centigrade, under RH<80%, and without conducting dust, explosive gas and corrosive gas.

02 The Operation Principles
The centrifuge machine helps to separate, condense or purify the different density
components ( or particles ) of the solutions by the usage of centrifugal sedimentation
principal.
After placing the centrifuge tubes with equivalent test solutions in the test tubes around the
rotors symmetrically and starting the machine, the RCF produced in the high-speed rotary of
the rotors, which are driven by the motor, separates the different density components ( or
particles ) in the test solutions. The value of RCF depends on the rotating radius “r” ( the
horizontal distance from the position of the test solutions to the axle center ) and the rotating
speed “n”, and here is the calculation formula.
RCF＝. 8× 0-6n2r×g
n------------ The rotating speed ( r/min )
r------------The rotating radius ( mm )
The time ( Ts ) needed during the separation and deposition of the mixed solutions is
calculated by this formula:
27.4× ( logeRmax-logeRmin ) μ
Ts ＝min
n2r2 ( б-ρ )
Type: Rmax------The rotating radius of the test solutions having the farthest distance with the
axle center
Rmin------The rotating radius of the test solutions having the nearest distance with the axle
center
ρ------The density of the mixed solutions ( g/cm3 )
μ------ The viscosity of the mixed solutions ( p )
n ------ The rotating speed ( r/min )
r------The particle’s radius ( cm )
б------The particle’s density ( g/cm3 )

05 The Operation Procedures
Step : Place the centrifuge machine on the platform and ensure its balance. Shake the
machine with hands to check out whether the machine has been placed stably or not.
Step 2: Plug the supply cord into the outlet and press down the power switch ( the power
switch is on the right bottom of the machine ).
Step 3: After pressing down the button of “ STOP & OPEN”, put the rotors on the motor
shaft, and connect the rotors with motor shaft tightly together by tightening the screw nuts
( the move should be very gentle and substantially shaking and pressing should be avoided,
so as to protect the flexible support system of the motor. Then, place the adapter with test
tubes on the rotors and rotate the rotors. The rotors should be turned flexibly, the adapter
should be rotated freely, and there should be no block or collision.
Step 4: Place the centrifuge tubes into the test tubes. The centrifuge tubes should be placed
symmetrically, and the test solutions in the tubes should be even, so as to make sure the
equilibrium operation of the machine.
Step 5: Cover the faceplate and check out whether it is covered tightly, or the centrifuge
machine cannot be operated.
Step 6: Set up the rotor mode, the rotating speed and the needed time.
The control panel of the machine is as shown below.

7) When counting down to 0, the centrifuge machine stops working automatically. During the
operation, pressing the “ STOP & OPEN” button can also stops the operation of the
machine. When the rotating speed reaches 0, the buzzer would make a buzzing sound, and
the cue words would be displayed on the window. The faceplate can be removed.
8) When press the “ IMPULS” button and hold for a few seconds, the rotors would start
rotation slowly; when the rotating speed reaches its fastest speed, the rotors would not
accelerate the speed any more. When relax the “ IMPULS” button, the rotors begin the
deceleration until they stop rotating. During the deceleration process, the “ IMPULS”
button cannot be pressed any longer; when the rotors stop the rotation completely, the
centrifugal process would restart by pressing and holding the “ IMPULS” button.
9) After the rotors stop the rotation completely, press the “ STOP & OPEN” button to
uncover the faceplate ( if the faceplate could not be removed because of its high rebound
force against the seal ring on top of the centrifugal chamber, please press the faceplate
slightly with one hand and repress the “ STOP & OPEN” button with the other to open
the faceplate ) , and take out the centrifugal tubes carefully. The whole separation process is
done.
0) Turn off the power switch, and cut off the power of the centrifugal machine.

06 Safety Notice
. This machine should not be used in the humid places with high temperature and large
fugitive dust.
2. To ensure the safety and its centrifugal effect, this machine should be placed in the
solid, quakeproof and horizontal platform, and all four undercarriages should be given
the balanced load.
3. The solutions in the centrifugal tubes should be seen as even as possible. If the
solutions in the tubes vary too much, there would be a large scale of vibration. In this
kind of situation, the operating machine should be stopped its operation and checked
to meet the requirement of the solutions in the tubes. The centrifugal tubes should be
placed symmetrically in the even numbers, and the nut caps connecting the rotors with
the motor shaft should be tightened.
4. During the operation process, the centrifugal machine cannot be moved, and the
faceplate cannot be uncovered.
5. The faceplate should not be uncovered in the situation that the motor and the rotors
do not stop the operation completely.
6. The power supply has its own earth wire, so the null line and the earth wire cannot be
used together, so as to prevent the damage of electric shock.
7. After the whole separation, the centrifuge machine should be cleaned up in time, the
power switch should be turn off, and the power supply should be cut off.
8. It should be very careful to take out the rotors. The proper way is to knock upward
slightly the rotors on the bottom by using nonmetal tools ( like the handle of the
screwdriver ) until the connection between the rotors and the motor shaft becomes
loose. The rotors should not be pulled out directly with hands after loosening the nut
caps, so as not to damage the flexible support system of the machine.
9. The rotors ad the centrifugal tubes should be checked regularly. If there are any cracks
or aging phenomena, those components should be replaced immediately.
Instruction: There is an emergency device on the bottom of the machine. If the sample
should be ta en out during the power outage, the faceplate can be uncovered by
pulling the stainless wire on the bottom after the rotors stop the operation. But this
device is forbidden to be used during the operation process.
