Rotor Centrifuge

The rotor centrifuge utilizes a motor to drive the rotor at high speed, generating centrifugal force to stratify and settle components of different densities in the sample. It is used for separating suspensions, extracting precipitates, and processing blood, cell, and paint samples in the laboratory.
Selection
When selecting, consider matching the sample capacity to the rotor specifications, ensure the speed range covers experimental requirements, and pay attention to the material's corrosion resistance. The temperature control function should be determined based on sample characteristics. Confirm the compatibility of the rotor with the host machine, and refer to the actual usage environment for noise and energy consumption parameters.
