LI-HRC-24K High Speed Refrigerated centrifuge
LI-HRC-24KHigh Speed Refrigerated 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 vibration-absorption effect of this machine works very well by the application of its special damper. This machine also has a self-balance function.
The special PWM-controlled speed control systemassures 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 motoralso 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.
This machine has a parameter-saving function, and it can calculate the RCF value automatically.
There are many rotors with different levels. The tube frame can be replaced, and there are many tubes, convenient to choose.
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.
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.
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:
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)
