Performance Requirements for Low-Speed Centrifuges

80-2-4

Digital Control & Safety:

  • Parameters can be set and modified when the centrifuge is in standby mode; programs can be locked.
  • During operation, all parameters except rotor type can be adjusted and locked.
  • Maximum speed limit function: rotor type must match the actual rotor used. If an incorrect maximum speed higher than the rotor’s rated value is set, the system will issue an error warning.

Speed Accuracy:

  • Within the operating speed range:
    • Variable frequency speed control: ±50 r/min.
    • Voltage regulation speed control: ±200 r/min.

Noise & Vibration:

  • Noise level ≤ 65 dB under maximum speed and full load.
  • Whole-machine vibration amplitude ≤ 0.1 mm.

Timing & Operation:

  • Timer range ≥ 59 minutes.
  • Continuous working time ≥ 4 hours without abnormal operation.

Temperature Control:

  • Air-cooled chamber; chamber temperature ≤ ambient temperature + 10 °C during operation.

Display Functions:

  • Relative centrifugal force (RCF) can be converted and displayed in real time during operation.
