Principle

1. High speed refrigerated centrifuge uses centrifugal force to stratify sample substances (cells, particles, proteins, etc.) by density. Heavier substances are pressed to the bottom, lighter ones remain at the top. The freezing function keeps the temperature constant, preventing sample deterioration or degradation.
2. Centrifugal force is generated by high-speed rotation, causing denser sample components to sink and lighter ones to rise, achieving separation.
3. The internal refrigeration system keeps the temperature low during centrifugation, protecting temperature-sensitive samples from unwanted reactions.
