In the world of laboratory research and diagnostics, precision is not a luxury—it’s a necessity. Pipette accuracy testing services play a vital role in maintaining the reliability and credibility of results. At our company, we specialize in providing comprehensive pipette accuracy testing and calibration solutions designed to meet the most stringent regulatory and quality assurance standards.

Why Pipette Accuracy Testing Matters

Every experiment, every assay, and every data point depends on the precision of liquid handling instruments. Pipette accuracy testing ensures that each instrument dispenses the correct volume, minimizing the risk of costly errors, unreliable results, and compromised research integrity.

Over time, even the most premium pipettes can drift from their original calibration due to wear, contamination, or improper use. Regular testing identifies deviations early, ensuring compliance with ISO 8655, GLP, GMP, and FDA standards.

Comprehensive Pipette Testing and Calibration Services

We deliver a full spectrum of pipette testing services, covering single-channel, multi-channel, electronic, and adjustable-volume pipettes. Our advanced methods ensure accuracy, repeatability, and consistency across all instruments.

Gravimetric Testing

This is the gold standard for pipette calibration. Using high-precision analytical balances in a temperature- and humidity-controlled environment, we measure dispensed volumes gravimetrically. Our process corrects for air buoyancy and evaporation loss, ensuring ultra-accurate volume determination.

Photometric Testing

For higher throughput environments, we offer photometric accuracy testing using colorimetric solutions. This technique provides rapid verification of pipette performance while maintaining precision within traceable tolerances.

On-site Calibration

Our mobile calibration labs allow us to perform on-site pipette testing without disrupting your daily workflow. Each on-site service follows the same stringent procedures as our controlled laboratory, ensuring full compliance and traceability.

Laboratory-Based Calibration

For customers who prefer off-site testing, we offer laboratory-based pipette accuracy verification in an environment maintained at optimal temperature, humidity, and barometric pressure conditions. Each pipette is tested multiple times to verify both accuracy and precision.

Adherence to International Standards

All our pipette accuracy testing and calibration procedures strictly comply with:

• ISO 8655: Requirements for piston-operated volumetric apparatus.
• GLP (Good Laboratory Practice) and GMP (Good Manufacturing Practice) guidelines.
• NIST-traceable calibration standards, ensuring traceability to the U.S. National Institute of Standards and Technology.

Our certifications and documentation provide the assurance that your instruments meet or exceed industry standards for performance and reliability.

Precision Equipment and Controlled Conditions

We invest in state-of-the-art technology to deliver precise results. Our calibration balances have microgram-level readability and are routinely verified with NIST-traceable weights. Environmental factors—temperature, humidity, and air pressure—are continuously monitored and recorded during testing to ensure the highest level of accuracy.

Every step of our process is documented using digital calibration management systems, offering seamless record-keeping, audit readiness, and easy retrieval of service histories.

Multi-Level Calibration Options

Different laboratories have different accuracy requirements. We provide customized calibration levels tailored to your applications and compliance needs.

Standard Calibration

Includes testing at the nominal volume, ensuring accuracy for general laboratory use.

Intermediate Calibration

Verifies pipette performance at three volume points—10%, 50%, and 100%—to ensure linear accuracy across the full range.

Accredited Calibration

Performed under ISO/IEC 17025 accreditation, this service provides the highest level of traceability and confidence, ideal for regulated industries such as pharmaceutical, biotech, and clinical diagnostics.

Documentation and Certification

Each pipette serviced by our technicians receives a detailed calibration certificate that includes:

• Pipette make, model, and serial number.
• Calibration results for each tested volume.
• Environmental conditions during testing.
• Technician identification and signature.
• Statement of traceability to NIST standards.

Certificates are available in both digital and hard copy formats, ensuring seamless integration into your quality management systems (QMS).

Frequency of Pipette Accuracy Testing

The ideal calibration frequency depends on several factors, including:

• Frequency of use
• Type of liquids handled
• Criticality of application
• Manufacturer’s recommendations

For high-precision applications such as pharmaceutical manufacturing or clinical testing, we recommend quarterly calibration. For general research environments, biannual or annual testing may suffice. Our experts can help establish a custom calibration schedule aligned with your operational requirements and compliance goals.

Signs Your Pipette May Need Recalibration

Even well-maintained pipettes can drift from specification. Common indicators that your pipette needs recalibration include:

• Inconsistent or unexpected assay results.
• Dripping or leaking tips.
• Difficulty achieving repeatable volume delivery.
• Mechanical stiffness or looseness in plunger action.
• Visual contamination or residue buildup.

Routine performance checks combined with professional calibration are the best ways to prevent costly downtime or rework.
