Laboratory Calibration Services for Clinical CAP & CLIA Laboratories

ISO/IEC 17025 laboratory calibration is performed by a laboratory that has been independently assessed and accredited as technically competent by a recognized accreditation body such as A2LA or NVLAP. An ISO 17025 accredited calibration certificate includes documented measurement uncertainty — a mandatory requirement for instrument qualification under GMP, GLP, FDA, CAP, and CLIA compliance programs. Without accreditation, a calibration certificate cannot demonstrate that the laboratory’s reference standards and measurement processes meet the technical competency requirements of these regulatory frameworks. Femto Scientific’s ISO/IEC 17025 accredited certificates are accepted by FDA inspectors, CAP surveyors, and international quality auditors as evidence of instrument performance and regulatory compliance.

A NIST traceable calibration certificate documents that the calibration results were obtained using measurement standards with an unbroken chain of comparisons to the National Institute of Standards and Technology (NIST) national measurement standards. For each instrument type, traceability is established through the appropriate measurement quantity: mass (OIML weights) for balances, volume (gravimetry) for pipettes, rotational frequency for centrifuges, and temperature (ITS-90) for thermometers. Femto Scientific uses NIST-traceable reference instruments with current calibration certificates maintained on a documented recertification schedule — ensuring your calibration documentation satisfies FDA, CAP, CLIA, and ISO requirements for measurement traceability.

Calibration frequency depends on regulatory requirements, instrument criticality, usage intensity, and environmental conditions. As a general guideline: pipettes are typically calibrated every 3–6 months in GMP environments and every 6–12 months in research labs; balances are calibrated every 6–12 months; centrifuges are calibrated annually; and thermometers are calibrated every 6–12 months. CAP and CLIA require calibration per the manufacturer’s instructions, with CLIA calibration verification at least every 6 months for many quantitative test systems (and after reagent-lot or major-maintenance changes). GMP and GxP programs require calibration intervals to be justified in instrument qualification documentation. Femto Scientific can help you establish and document calibration intervals appropriate for your specific regulatory environment and instrument usage patterns.

Femto Scientific provides ISO/IEC 17025 accredited calibration, repair, and preventative maintenance for the full range of laboratory measurement instruments, including: pipettes and automated liquid handlers; analytical, precision, and industrial balances and mass weight sets; centrifuges; thermometers, RTDs, and thermocouples; temperature-controlled equipment such as incubators, ovens, refrigerators, and freezers; humidity and temperature data loggers; pH meters; autoclaves and steam sterilizers; CO₂ incubators; thermal cyclers and PCR instruments; UV-Vis and FTIR spectrophotometers; and HPLC systems. We service instruments from every major manufacturer. If your instrument type is not listed, contact us — our metrologists support virtually all makes and models of laboratory measurement equipment. Biosafety cabinets and fume hoods are certified to NSF/ANSI 49 and ASHRAE 110 as a separate certification service — they are tested and certified, not calibrated.

Yes. Femto Scientific provides onsite laboratory calibration services in major U.S. laboratory markets including New York, New Jersey, Boston, Philadelphia, Baltimore, Connecticut, California, Texas, and more. Our technicians travel fully equipped with NIST-traceable reference standards appropriate for each instrument type — nothing for your team to prepare. Onsite service is available for pipettes, balances, centrifuges, and thermometers at all four service levels. For laboratories outside our direct service territory, our secure mail-in calibration service provides the same ISO 17025 accredited certificates and NIST traceability with fast turnaround and electronic certificate delivery.
