Overview
What is Centrifuge Pump Calibration?
Centrifuge-based procedures — binder extraction, filler determination, sample separation — assume the rotor actually runs at its set speed. Worn brushes, drive slippage and ageing controls make displayed RPM drift from true RPM, quietly changing separation efficiency and test outcomes.
Global Lab verifies true rotational speed with NPLI-traceable non-contact (optical/laser) tachometers at the working set-points, checks run-timer accuracy against reference chronometers, and certifies deviation with uncertainty — flagging units whose speed error exceeds the tolerance of the method they serve.

NPLI-Traceable References
Reference standards with unbroken traceability to national standards.
ISO/IEC 17025 System
Calibration under our accredited laboratory quality system.
True-RPM Verification
Optical tachometer measurement at working set-points.
Fast Turnaround
Certificates in 2–4 days — minimal instrument downtime.
As-Found / As-Left Data
Both states recorded, so drift since last calibration is visible.
Digital Certificates
Calibration certificates via the Autovity QLMS dashboard.
Test Procedure
How the Centrifuge Pump Calibration is Conducted
- 1
Condition & Safety Check
Rotor seating, lid interlock and vibration behaviour are inspected before running. - 2
Speed Measurement
True RPM is measured with a traceable non-contact tachometer at each working set-point after stabilisation. - 3
Timer Verification
Run-timer accuracy is checked against a reference chronometer over representative durations. - 4
Evaluation
Deviations are evaluated against the applicable method tolerance. - 5
Certification
Set-point vs true-speed table with uncertainty is issued via Autovity QLMS.
