Yingtai: Advantages of Large-Capacity Horizontal Rotors in Centrifugation

Yingtai: Advantages of Large-Capacity Horizontal Rotors in Centrifugation  

1. Ultra-Large Volume Processing with Broad Compatibility  

- Supports tubes ranging from 15 mL to 500 mL, meeting clinical batch-processing needs (e.g., blood bank plasma separation, vaccine production).  

- Fixed-angle rotors are typically limited to 1.5–10 mL tubes, requiring multiple runs for large volumes, reducing efficiency.  

- Industrial-scale throughput design: 6–8 tube slots enable parallel processing (e.g., simultaneous separation of 48×15 mL whole blood samples), ideal for high-throughput screening.  

2. Gentle Separation for Sample Protection  

- Low-shear environment: Swinging buckets distribute force evenly, avoiding the compression effects of fixed-angle rotors, minimizing cell damage (e.g., 15% higher stem cell recovery).  

- Superior preservation of fragile samples (e.g., exosomes, platelets).  

- Sharp interphase: Maintains clear separation layers even at large volumes (e.g., distinct plasma/RBC boundary), reducing cross-contamination.  

3. Operational Convenience  

- Easy recovery: Pellets concentrate at the tube bottom, allowing direct decanting or pipetting of supernatants.  

- Gradient centrifugation: Better stability for sucrose/iodixanol gradients, ideal for virus purification.  

- Automation-friendly: Compatible with liquid-handling robots for unmanned batch processing.  

4. Irreplaceable in Specialized Applications  

- Biopharmaceuticals: Maintains protein activity during large-volume precipitation or monoclonal antibody purification, whereas fixed-angle rotors may cause aggregation or denaturation at high speeds.  

- Environmental monitoring: Enhances detection sensitivity for microplastics/algae enrichment in water samples.  

5. Considerations  

- Speed limit: Large-capacity horizontal rotors typically max at ≤6,000 rpm (requires balancing).  

- Consumable cost: Dedicated large-volume tubes are pricier but reusable.
