First clarify the requirements for sample experiments, then select products based on those requirements.
1. What type of samples need to be processed? What is the maximum relative centrifugal force required for each type of sample?
2. What are the maximum, typical, and minimum sample volumes required for the experiment?
3. Is temperature control required during processing? Is biological protection required?
After understanding the requirements, consider the performance and parameters of the centrifuge from the following 6 aspects:
1. Temperature control range
Refers to whether a freezing function is needed when separating samples. Some samples (such as proteins, cells, etc.) will be damaged in high-temperature environments, so a refrigerated centrifuge should be chosen. It should be noted that centrifuges generate heat during high-speed operation. This heat will be balanced with the centrifuge's refrigeration system at a certain temperature, and this temperature range is the true temperature during the experiment.
2. Centrifuge speed and centrifugal force
The higher the rated speed of a laboratory centrifuge, the higher the centrifugal force generated, and the stronger the separation capability. Speed is divided into main unit rated speed and rotor rated speed. The main unit's rated speed is not necessarily the rated speed for every rotor.
3. Centrifuge capacity
The total capacity of the centrifuge = capacity per centrifuge tube × number of centrifuge tubes. The total capacity should match the workload.
4. Centrifuge rotors
Common types are horizontal rotors and angle rotors. When a horizontal rotor operates, the buckets are in a horizontal position, perpendicular to the axis of rotation, and samples will be concentrated at the bottom of the centrifuge tube. With an angle rotor, the axis of rotation forms a fixed angle with the container, and samples will be concentrated at the bottom and near the side walls of the centrifuge tube. There are also some special rotors: large capacity buckets (mostly used in blood banks), microplate rotors, slide rotors, PCR rotors, test tube rack rotors, and capillary rotors, etc.
5. How is the biosafety airtightness, and can it prevent aerosol overflow to ensure the safety of the laboratory environment?
6. Control system
High-end centrifuges all adopt microcomputer control systems. Adjustable speed, settable time, settable programs, such as Xiamen Guoyi refrigerated centrifuges.
