Both laboratory centrifuges and industrial centrifuges are currently for sale with good prices and excellent service.
Definition of Centrifuge
The centrifuge refers to a machine that can rotate at a high speed and use centrifugal force to separate substances of different densities. There are laboratory centrifuges and industrial centrifuges below, which are applicable for different situations, but both of them play a significant role in a great variety of fields.
Introduction to centrifuge
A laboratory centrifuge is mainly composed of four parts: the driving system, various centrifugal rotors, the temperature control system and the whole machine control system. As their name suggests, four parts have different functions.
- Driving System: Adopting the brush-less frequency conversion motor, it can output the maximum torque at different speeds.
- Centrifugal Rotors: Various centrifugal rotors can be used to separate a great variety of biological samples.
- Temperature Control System: There are two types of temperature control, including low and normal temperature control. It possesses the pre-cooling procedure and the function of maintaining constant cooling in standby state.
- Whole Machine Control System: It mostly adopts micro computer to control the machine, and control panel with LCD screen and digital display, which is used to control the whole machine.
Industrial Centrifuge (Ethanol Extraction Equipment)
An industrial centrifuge or the ethanol extraction equipment has a complicated system, generally consisting of six parts. Something detailed as follows.
- Driving System: It refers to the motor(carbon brush motor, brushless motor, variable frequency motor). It is the heart of the centrifuge and contains the electric motor, which is an important component of the centrifuge.
- Control System: The control system refers to the circuit board/main board, and display board. The control system is the command center of the centrifugal extraction system. The principle is the same as that of the computer. It mainly processes and controls various data.
- Rack/Chassis: The rack or chassis connects the centrifuge parts, which is the over of centrifuge and can protect centrifuge from being damaged.
- Centrifugal Chamber: The centrifugal chamber accommodates the motor.
- Rotor: The rotors are used to place specimen, including the horizontal rotor, angular rotor, ELISA plate rotor and cell picture rotor.
- Compressor(Freezer Type): The compressor (freezer type) refers to the temperature control. The centrifugal compressor is a kind of turbo compressor, which has the characteristics of the large gas volume, small volume, simple structure, stable operation, convenient maintenance and gas pollution from oil, and many driving modes are available.
How does a Laboratory Centrifuge Work?
A laboratory centrifuge works on the sedimentation principle, which makes of centrifugal force to separate components of a sample based on their density. The centrifugal force is generally generated by the spinning of the centrifuge.
How does an Industrial Centrifuge Work?
The working process of an industrial centrifuge can be roughly concluded as follows. The centrifuge has a cylinder(drum) that rotates at a high speed, which is usually driven by an electric motor. After the suspension (or emulsion) is added to the drum, it is rapidly driven to rotate at the same speed as the drum, and the components within the mixtures are separated under the function of the centrifugal force and discharged separately. Generally, the higher the drum speed is, the better the separation will be. When the suspension containing fine particles is left still, the suspended particles gradually sink due to the action of the gravitational field. The heavier the particles are, the faster they sink.
