Calibration of piston-operated volumetric apparatus (pipettes), accredited according to ISO/IEC 17025

Calibration of piston-operated dispensers (pipettes) is a critically important procedure for ensuring the accuracy, repeatability, and reliability of liquid volume measurements in laboratory practice. Even minor deviations in dosing can lead to significant errors in analytical results, disruptions in technological processes, or non-compliance with regulatory and industry standards.

We provide professional calibration services for piston-operated volumetric apparatus in accordance with the requirements of the international ISO 8655 standards, with the issuance of an ISO/IEC 17025 calibration certificate and full metrological traceability to national standards.

FAQ - Calibration of Piston-Operated Volumetric Apparatus

What are piston-operated volumetric apparatus and where are they used?

Piston-operated volumetric apparatus are instruments designed for accurate dispensing and measurement of liquid volumes, where the volume is determined by the movement of a piston. These include laboratory pipettes, dispensers, dilutors, and multichannel systems. They are widely used in pharmaceutical, biotechnological, clinical, chemical, and research laboratories.

Why is calibration of piston-operated volumetric apparatus critically important?

Even minor deviations in dosing can lead to significant errors in analytical results, disruptions in technological processes, or non-compliance with regulatory requirements. Regular calibration ensures the reliability of results, repeatability of measurements, and compliance with ISO, GLP, and GMP requirements.

Which types of devices are subject to calibration?

We perform calibration of:

single-channel piston-operated devices with fixed and variable volume;
multichannel systems with up to 12 channels;
positive displacement pipettes;
electronic and automated dispensers;
repeating dispensers, syringes, dispensers, dilutors, and titrators.

How often should piston-operated volumetric apparatus be calibrated?

The recommended calibration interval is once every 12 months, or more frequently depending on the intensity of use, operating conditions, and the requirements of the company’s internal procedures.

Which calibration method is used?

The gravimetric method is used, which involves weighing the dispensed liquid and then converting mass into volume. This method is considered the reference method and allows the lowest measurement uncertainty to be achieved.

What documents do you receive after calibration?

The customer receives an ISO/IEC 17025 calibration certificate, which contains:

measurement results;
deviations from nominal values;
uncertainty evaluation;
information on metrological traceability.

What are the advantages of accredited calibration?

Accredited calibration ensures:

legal and technical correctness of results;
international recognition of certificates;
full metrological traceability;
minimum measurement uncertainty.
