Interpretation of Key Components of the Miniature Centrifuge

　　Laboratory centrifuges are essential equipment in life science research, typically consisting of three main components: the centrifuge body, the rotor, and the centrifuge tubes. Today, laboratory centrifuges are widely used in the biopharmaceutical industry due to their promising market prospects. The variety of centrifuge types is continually expanding; as far as I know, there are high-speed centrifuges, low-speed centrifuges, refrigerated centrifuges, laboratory centrifuges, large-capacity centrifuges, mini centrifuges, biopharmaceutical centrifuges, automatic cap-removal centrifuges, cell centrifuges, benchtop micro high-speed centrifuges, Xiangyi centrifuges, graphene centrifuges, medical centrifuges, and many others. Given the sheer number of types, it’s simply impossible to go into detailed descriptions of each one. So today, taking the mini centrifuge as an example, I’ll provide a thorough introduction to relevant industry technical information.
　　 To determine whether a mini centrifuge is qualified—or, in other words, of high quality—the first thing to look at is the rotor, which is a crucial component of the centrifuge. Generally, there are dozens of rotor types available to users, each with different capacities and performance characteristics. Based on the angle between the axis of the centrifuge tube and the axis of the centrifuge rotor during rotation, mini-centrifuge rotors can be broadly categorized into three types: angled rotors (with angles ranging from 14° to 40°), vertical rotors (with an angle of 0°), and horizontal rotors (with an angle of 90°). Each rotor in a mini-centrifuge has specified usage limits, namely the maximum number of rotations (independent of rotational speed) and the maximum duration of operation at the highest speed. If a rotor has reached its specified usage limit but is still used beyond that point, its maximum rated speed must be reduced by 10% to ensure safe operation. In terms of management, a separate file must be established for each rotor, recording the number of times it has been used as well as the duration of operation at its maximum speed. Furthermore, the maximum rated speed indicated on the rotor is conditional; during actual use, operators must strictly adhere to these specified conditions.
　　The rotor is an essential component of a mini centrifuge, and typically dozens of rotors with various capacities and performance characteristics are available for users to choose from. Based on the angle between the axis of the centrifuge tube and the axis of the centrifuge rotor during rotation, centrifuge rotors can be broadly classified into three types: angular rotors (with angles ranging from 14° to 40°), vertical rotors (with an angle of 0°), and horizontal rotors (with an angle of 90°). Each rotor used in high-speed and ultracentrifuges has specified usage limits, namely the number of rotations allowed (independent of rotational speed) and the maximum duration of operation at the highest speed. If a mini centrifuge rotor has reached its specified limit but continues to be used, its maximum rated speed must be reduced by 10% to ensure safe operation. In terms of management, each rotor must have its own separate file, recording the number of times it has been used and the duration of operation at its maximum speed. Furthermore, the maximum rated speed indicated on the rotor is conditional; actual use must strictly adhere to these specifications.
　　Only when the operating speed of a mini-centrifuge falls outside the critical speed range can the rotor rotate smoothly. For low-speed refrigerated centrifuges with relatively low operating speeds, the critical speed is generally raised as much as possible, ensuring that the centrifuge operates below its critical speed. Such centrifuges feature a thick shaft with high rigidity, referred to as a rigid shaft. When higher rotational speeds are required, the critical speed is minimized as much as possible, and the shaft is made thinner with lower rigidity—this type of shaft is called a flexible shaft. Modern ultracentrifuges all employ flexible shafts.
　　 The centrifuge tubes and their caps are essential accessories for the rotor in a mini-centrifuge. The materials commonly used to manufacture centrifuge tubes fall into three main categories: special glass, plastic, and stainless steel. Selection should be made based on the material properties and the requirements of the centrifugation experiment.
