Laboratory Equipment Calibration Services

What Is Laboratory Equipment Calibration?

Laboratory equipment calibration is the process of comparing your instrument's measurements against a known reference standard and making adjustments to ensure accuracy. This verification ensures your equipment delivers consistent, reliable results that meet regulatory requirements.

Calibration is performed by comparing your instrument's output to a NIST-traceable reference standard. Any deviations are documented, and adjustments are made to bring the equipment back within specification. This process is essential for any instrument that performs measurements in your laboratory.

At Nexus Metrology, all calibration services are performed in accordance with ISO 17025 standards and are fully NIST-traceable, ensuring your results will withstand regulatory scrutiny.

How Often Should Lab Equipment Be Calibrated?

Calibration frequency depends on several factors including equipment type, usage intensity, manufacturer recommendations, and regulatory requirements. In general, most lab instruments require calibration every 6 to 12 months.

However, you should also calibrate equipment:

Before any critical or high-stakes processes
After any incident involving the equipment (drops, power surges)
When measurement data appears questionable
After repairs or maintenance
When relocating equipment

Our metrology experts can help you establish an optimal calibration schedule based on your specific equipment and operational requirements.

Frequently Asked Questions

How often should lab equipment be calibrated?

Typically, laboratory equipment should be calibrated every 6 to 12 months, depending on the instrument type, usage frequency, and manufacturer recommendations. Critical instruments may require more frequent calibration. Our team can help establish the optimal schedule for your equipment.

How does calibration affect lab results?

Without proper calibration, your lab equipment may produce inaccurate measurements, leading to poor data quality, skewed results, and potential compliance issues. Regular calibration ensures your measurements are accurate, reproducible, and trustworthy.

What are the benefits of on-site vs. off-site calibration?

On-site calibration minimizes instrument downtime and eliminates the risk of damage during transport. Your equipment stays in your facility and is ready to use immediately after calibration. Off-site calibration in our accredited lab may be preferred for certain specialized equipment or when more controlled conditions are required.

What is ISO 17025 accreditation?

ISO/IEC 17025 is the international standard for testing and calibration laboratories. Accreditation to this standard demonstrates that our calibration laboratory operates with technical competence, produces valid results, and maintains a quality management system. This is the primary accreditation recognized for calibration services worldwide.

What documentation do you provide?

We provide comprehensive calibration certificates that include all measurements, as-found and as-left data, traceability information, uncertainty statements, and pass/fail determinations. Our documentation is audit-ready and complies with FDA, GxP, and ISO requirements.
