The utility model has the advantages of simple structure, and is composed of a motor, a centrifugal turntable, a governor, a timer, a centrifugal sleeve and a base. Motor: It is the main part of the centrifuge, mostly in series. It consists of a stator and a rotor. The series-excited motor has a large starting torque. As the load increases, the speed drops rapidly and the speed is high at no load. Centrifugal turntable (rotary head): The centrifugal turntable is usually made of cast aluminum, with a flat top taper and a round hole in the middle. It is placed on the rotating shaft at the upper end of the motor and then screwed tightly with a nut. The turntable has 6-12 symmetry. An inclined hole at a 45° angle to place the test tube. Speed ​​control device: (Control motor) There are many types, such as multi-tap varistor, porcelain disk variable resistor and so on. A multi-tap choke or porcelain disk variable resistor is connected in series between the power supply and the motor to change the current and voltage of the motor, and the speed adjustment is achieved by rotating or touching the panel automatic control system. Centrifugal sleeve: Mainly made of plastic and stainless steel. The plastic centrifuge tube is transparent (or translucent). It is commonly used in materials with good performance, such as polypropylene (PP). Its hardness is small. The gradient layer can be taken out by puncture method, but it is easy to deform, has poor corrosion resistance to organic solvents, and has short service life. The plastic centrifuge tube has a tube cover, and the tube cover must be tightly sealed before centrifugation to prevent leakage when inverted. The stainless steel centrifugal tube has high strength, no deformation, and can resist heat, frost and chemical corrosion.
