A centrifuge laboratory equipment is used to extract serum from whole blood; extract supernate from all kinds of samples; fast sedimentation of sample; separate microscale blood corpuscle; sample treatment of microorganism. When selecting a lab equipment centrifuge, you’d better know following basic facts to better select a suitable centrifuge laboratory equipment.
1.Rotating speed: according to different max rotating speed, there are low speed lab equipment centrifuge(<10000rpm/min); high speed lab equipment centrifuge(>10000 rpm/min-30000 rpm/min); and ultra centrifuge(>30000 rpm/min). But the separating effect is mainly decided by centrifugal force, not rotating speed, so as long as the separating effect meet your requirements, the experiment will be done.
2.Temperature: some sample such as cell and protein will be damaged in high temperature environments, at this time, a freeze centrifuge is needed.
3.Volume: you must know clearly about the volume you need for the experiment, the total capacity of a lab equipment centrifuge is depended on the amount and volume of centrifuge tubes.
4.Rotor: there are two types of rotors for your choice: horizontal rotor and angle rotor. Choose the horizontal rotor if you need sample to concentrate on the bottom of centrifuge tube; choose the angle rotor if you need sample to concentrate on the bottom of centrifuge tube and nearby the side wall.
5.Control system: lab equipment centrifuge use microcomputer control system to ensure the safety operation. Some advanced modern centrifuges are equipped with rotor recognition function, safe lock function, self-balance function, malfunction alert function and other details.
6.Motor: motor is the most important part for a centrifuge laboratory equipment, most modern centrifuges use brushless DC motor. Except for motor, noise is another factor you should consider.
