Calibration Record: Centrifuge Speed, Time & Temperature

Instrument: Centrifuge
Calibration Parameters: Speed, Timer, Temperature
Calibration Procedure:

▸ Speed Calibration:
Tested at multiple speed setpoints (e.g., 1,000, 3,000, 5,000 rpm) using a tachometer to verify the accuracy of displayed speed.

▸ Time Calibration:
Used a stopwatch to compare with instrument’s built-in timer at set intervals, ensuring consistency.

▸ Temperature Calibration (for refrigerated centrifuges):
Used a reference thermometer to monitor internal temperature at common setpoints (e.g., 4°C, 20°C) to assess stability and accuracy.

Key Observations:

• Ensures accurate centrifugal performance

• Prevents experimental deviation due to timing or speed errors

• Calibrations conducted following ISO standards
