Centrifuge Calibration for CAP & CLIA Clinical Laboratories

Calibration frequency depends on regulatory requirements, instrument criticality, and usage intensity. Pharmaceutical laboratories under cGMP typically calibrate centrifuges annually, with frequency justified in the instrument qualification documentation. Clinical laboratories under CAP or CLIA are required to calibrate centrifuges at least annually. Research laboratories without regulatory mandates typically calibrate annually. High-criticality centrifuges — those used in GMP cell culture, blood processing, or pharmaceutical separation processes — may require semi-annual calibration. Femto Scientific can help you establish an appropriate calibration interval for your specific compliance program.

As-found data documents the centrifuge’s RPM accuracy, timer accuracy, and temperature performance before any adjustment during the calibration visit, providing a record of how the instrument was performing since the last calibration. As-left data documents performance after adjustment or correction, representing the condition in which the instrument was returned to service. Both data sets together provide before/after documentation required by GMP change control programs, CAP inspection checklists, and instrument qualification protocols. Femto Scientific’s Level 3 and Level 4 service levels include both as-found and as-left data.

All service levels include a calibration sticker with barcode applied to the instrument. Level 2 and above include an electronic calibration certificate documenting as-left RPM and timer accuracy data at each calibrated set point. Level 3 and Level 4 additionally include as-found measurement data, documented expanded measurement uncertainty (k=2, 95% confidence), reference standard traceability information, environmental conditions during calibration, rotor inspection notes, and the ISO/IEC 17025 accredited laboratory identifier. Certificates are delivered electronically in PDF format and formatted for integration with quality management systems (QMS) and laboratory information management systems (LIMS).

Yes. Femto Scientific calibrates clinical and blood bank centrifuges including Beckman Coulter, StatSpin, Drucker, and Unico models used in blood bank operations, blood typing, crossmatching, and platelet separation. Blood bank centrifuge calibration verifies RPM accuracy and timer accuracy at the specific speed and time settings required by blood bank protocols, with documentation formatted to satisfy AABB, CAP, and CLIA inspection requirements for blood bank equipment qualification. Calibration is performed at your facility or by mail-in service.

Yes. Femto Scientific provides onsite centrifuge calibration across major U.S. laboratory markets including New York, New Jersey, Boston, Philadelphia, Baltimore, Connecticut, California, Texas, and many more cities. Onsite service is ideal for floor-standing centrifuges, ultracentrifuges, and large benchtop units that are difficult to ship, as well as facilities with large numbers of centrifuges requiring annual calibration in a single visit. Laboratories outside our direct service territory can use our secure, fast-turnaround mail-in centrifuge calibration service with NIST traceable certificates delivered electronically.
