Benchtop High Speed Refrigerated Centrifuge BCBHR-304
02 Features and Applications
1. BCBHR-304 Benchtop High Speed Refrigerated Centrifuge (BCBHR-304 is now will be
referred as this machine) is an advanced facility widely applied in biochemistry, health
and medicine, food safety, life science, agriculture science, grassland farming science,
blood bank, blood station, biological product, pharmacy product, to make sample
separation, precipitation and concentration, and it’s the high-tech product aiming at
replacing import facility and becoming export.
2. 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.
3. This machine adopts the advanced technologies like microcomputer control, direct
drive brushless DC motor, TFT Zhencai touch panel, mute mechatronics electronic lock
and so on.
The features of this machine are as followed:
. Step : 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.
2. 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.
3. 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.
4. 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.
5. 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.
03 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/cm )
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/cm )

06 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 motorshaft 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.
