A centrifuge is a machine that uses centrifugal force to separate ingredients from liquid and solid particles or a mixture of liquid and liquid. Centrifuge is mainly used to separate solid particles from liquid in suspension, or to separate two liquids of different densities in mutually incompatible emulsions (such as separating butter from milk); it can also be used to remove wet solids In the liquid, for example, use a washing machine to wash clothes dry. Special ultra-velocity tube separators can also separate gas mixtures of different densities; solid particles with different density or particle size with different settling speeds are used in the liquid, and solid particles can also be classified by density or particle size.

 

Choosing a reliable and well-known brand not only brings convenience to the use process, but also reduces the loss and trouble caused by future failures. For example, the casing of the centrifuge motor should be equipped with a double or multilayer safety protective cover, which is strong enough to prevent potential accidents, but people are still unaware of this danger, so you should pay attention to it when buying. These invisible details are actually a guarantee of safety, and the price is directly proportional to the quality. Other safety measures are also important, such as automatic rotor recognition (to prevent the set centrifugal speed from exceeding the limit), lid operation (the centrifuge can be started after the lid is locked, and the machine must be turned off after the machine is turned off) Facilities to ensure the safety of laboratory personnel Some centrifuges can also monitor the imbalance caused by tube rupture and sample overflow during the entire centrifugation process, or whether the rotor cover is properly closed.

 

Maintenance of the centrifuge is very technical. Installation and maintenance should be performed by professional maintenance personnel approved by the manufacturer. Therefore, the safety measures that must be considered when choosing a centrifuge should choose a reliable brand and sales unit. When using the centrifuge motor, please pay attention to any problems during the centrifugation process. A centrifuge with a locked lid may not be able to open the lid or take out precious samples. It is often difficult for maintenance personnel to arrive in time. Therefore, when choosing a centrifuge, there should be a manual cover for emergency use. When installing the machine, you must ask the engineer how to use the machine and read the centrifuge manual that supports the centrifuge. In the event of an accident, you can save valuable samples yourself.
