Benefits of cooperation

High measurement accuracy and repeatability

We use high-precision equipment and certified methods, ensuring stable and reliable results for every calibration.

Compliance with international standards

All work is performed in accordance with the requirements of ISO/IEC 17025, OIML, and other international standards, ensuring that the results are accepted for audits and quality control.

Fast turnaround times

Optimized processes and our own equipment allow us to perform calibration promptly, without delays in your production cycle.

Calibration method

Calibration is performed using the gravimetric method, which is the reference method for determining the actual volume. The method involves weighing the dispensed liquid and then converting mass into volume, taking into account temperature, atmospheric pressure, and other environmental parameters.

To ensure high accuracy, we use:

– analytical balances certified according to ISO/IEC 17025;
– certified thermometers, barometers, and reference weights;
– controlled measurement conditions.

FAQ - Calibration of Laboratory Glassware and Plasticware

What is calibration of laboratory glassware and plasticware?

Calibration of laboratory glassware and plasticware is a procedure for determining the actual volume and verifying that the metrological characteristics of the vessels comply with established requirements by comparison with reference measuring instruments.

Which laboratory glassware and plasticware is subject to calibration?

We calibrate laboratory glassware and plasticware, including:

burettes;
single-mark pipettes;
graduated pipettes;
volumetric flasks;
measuring cylinders;
pycnometers;
other volume measuring instruments.

Which standards is calibration performed according to?

Calibration is performed in accordance with the requirements of ISO 4787, with the issuance of a calibration certificate according to ISO/IEC 17025.

Which method is used during calibration?

The calibration method is the same; however, for plasticware, its temperature stability, material elasticity, and possible deformation are additionally taken into account.

Is calibration of glass and plasticware different?

The calibration method is the same; however, for plasticware, its temperature stability, material elasticity, and possible deformation are additionally taken into account.

How often should laboratory glassware and plasticware be calibrated?

The recommended calibration interval is once every 12 months or according to the laboratory’s internal procedures, GLP/GMP standard requirements, or the results of previous calibration.

What are the advantages of accredited calibration?

Accredited calibration ensures:

legal and technical correctness of results;
international recognition of certificates;
full metrological traceability;
