The key feature of a low-speed centrifuge is its emphasis on low rotational speed.

　　 Low-speed centrifuge The key point is to emphasize the low rotational speed—don't be surprised; it really is about highlighting the low RPM. Depending on the medium being separated, some media require production under low-speed conditions.
　　During centrifugation in a low-speed centrifuge, particles migrate to positions corresponding to their own densities, forming distinct bands. The selection of density gradients should ensure that the gradient range encompasses the densities of all particles to be separated. The sample can be placed either on top of the density medium or uniformly distributed throughout the density gradient. After centrifugation, the sample particles reach their equilibrium positions. Note: Once equilibrium is reached, the separation of particles is determined solely by their densities and is independent of time. At this point, any subsequent changes in centrifugal speed will only affect the relative positions of the bands.
　　Particles of different densities, sizes, or shapes sediment at different rates under centrifugal conditions with varying speeds. Therefore, a generally spherical, non-homogeneous mixture can be separated by centrifugation. Low-speed centrifuges are designed for further biochemical research and the separation of large quantities of substances. During operation, centrifugal stresses develop inside the rotor; once these stresses exceed a certain threshold, they can lead to premature rotor failure or even rotor rupture. Thus, users must pay close attention to the proper use and careful storage of rotors. After use, rotors should be promptly cleaned and never subjected to impacts or scratches. If a rotor is accidentally dropped, it must undergo an X-ray examination to confirm that there is no internal damage before it can be reused. During operation, rotors that have exceeded their service life should be promptly discontinued. Typically, Low-speed centrifuge Manufacturers specify both the total operating hours and the number of centrifugation cycles for rotor heads. Whichever of these two indicators is reached first indicates that the rotor head has reached the end of its service life. To extend the service life of low-speed centrifuge rotor heads, it is essential to strictly follow the manufacturer’s instructions. Generally, the maximum rotational speed of the rotor should be reduced under the following circumstances: ① The rotor head has reached its specified service life but remains in good condition; in this case, reduce the speed according to the manufacturer’s recommendations to extend its useful life; ② The rotor head exhibits localized damage or minor corrosion; ③ When using stainless steel centrifuge tubes and sleeves, and the average density of the sample exceeds 1.2 g/ml.

　　High-end low-speed centrifuges all feature microcomputer control systems. These control systems not only ensure the safe operation of the centrifuge but also enable the machine to automatically complete its tasks. Nowadays, many centrifuges come equipped with user-friendly control systems that offer a variety of convenient features—for example, rotor identification, safety lock functions, fault-alert indicators, and adjustable acceleration and deceleration curves. In addition to these key features, it’s important to pay attention to certain details and essential accessories. The main component of a low-speed centrifuge is the motor. Motors are categorized into brushed motors and brushless motors; the former have largely been phased out, and most modern centrifuges now use brushless motors. Some brushless motors even come with built-in braking functions.
