Centrifuge Calibration

Centrifuge calibration & RPM verification

Independent, NIST-traceable RPM and timer verification for clinical, molecular, and research centrifuges — performed on-site so your instruments never leave the lab.

Manufacturers we calibrate and service

RPM verification against a calibrated tachometer, timer accuracy, temperature verification on refrigerated units, and NFPA 99 electrical safety — documented on one NIST-traceable certificate per instrument.

Beckman Coulter

Allegra X-series, Avanti J-series, Microfuge and Optima benchtop and floor models.

Eppendorf

5810 and 5810R, 5920R, 5430 and 5430R, 5424 and 5424R, 5702 series.

Sorvall

RC-3C and RC-3C Plus, RC 6 Plus, Legend X1 and XTR, ST 8 / ST 16 / ST 40 series.

Thermo Fisher

Heraeus Megafuge and Multifuge, Pico 17/21, Fresco 17/21, Sorvall ST and Legend platforms.

Clinical benchtop

Hettich, Drucker Horizon, Unico, LW Scientific, Clay Adams Triac and comparable units.

Cytospins & specialty

Cytocentrifuges, hematocrit and serology centrifuges, and rotor-specific verification.

What every centrifuge calibration includes

01

RPM verification

Multi-point speed verification against a calibrated tachometer, with as-found and as-left values.

02

Timer accuracy

Run-time verification against a traceable reference — a common surveyor finding.

03

Temperature (refrigerated units)

Chamber temperature verification on refrigerated models.

04

Electrical safety

NFPA 99 leakage and ground verification on the same visit.

05

Mechanical inspection

Rotor, lid latch, gasket and brake condition — safety before certification.

06

Certificate & label

NIST-traceable certificate, dated calibration label, and next-due tracking.

Obsolete Sorvall controls?

When factory control electronics are discontinued — as they are on the RC-3C Plus — we retrofit rather than replace. See the SmartControl™ modernization system.

Accurate g-force, documented to tolerance

BMCA verifies actual rotor speed against the set value across the operating range using a NIST-traceable tachometer, checks the timer, and records as-found / as-left readings — the documentation CLIA assessors expect to see.

Why it matters

An out-of-tolerance centrifuge quietly undermines result quality and is an easy inspection finding. Verification closes the gap and gives you proof on file.

Centrifuge calibration & RPM verification — common questions

Why do centrifuges need calibration?
A centrifuge spinning off its set speed can compromise test results — separated samples, packed-cell volumes, and molecular preps all depend on accurate g-force. CLIA-regulated labs are expected to verify centrifuge performance on a schedule.
How is centrifuge RPM verified?
We measure actual rotor speed with a calibrated, NIST-traceable tachometer and compare it to the set speed across the rated range, and verify the timer. You receive a certificate showing set vs. measured values and the tolerance.
What tolerance is acceptable for a centrifuge?
It depends on the application and manufacturer specification — commonly within about ±5%. We document the as-found and as-left readings against your defined tolerance so the record is defensible.
How often should a centrifuge be calibrated?
Annual verification is typical, with more frequent checks for critical applications. We set and track the interval for you.
Do you verify all centrifuge types?
Yes — benchtop, microcentrifuges, refrigerated, and high-speed units across clinical, molecular, and research settings.
