Post-Calibration & Service

Experience comprehensive Post-Calibration care with AccuCal. Our meticulous process includes:
  Internal Cleaning and Inspection: Each pipette is dismantled, cleaned internally, thoroughly inspected, and leak tested. If needed, we replace any worn parts to ensure optimal functionality.
External Cleaning: Pipettes are meticulously cleaned externally to maintain their pristine condition.
Adjustment and Recalibration: If necessary, your pipette will be adjusted to meet the manufacturer's specifications and recalibrated for precise performance.
Certification: We provide a detailed Certification of Calibration for each pipette, documenting the results and any spare parts used.
Calibration Date Sticker: A sticker indicating the next calibration due date isapplied to each pipette, ensuring you stay on schedule.
Trust AccuCal for unparalleled precision and reliability in pipette calibration.

Pre-Calibration (As found)

Our pre-calibration service assesses the current performance of your pipette before servicing or as part of routine checks. This evaluation does not involve any adjustments; it simply reports how the pipette is functioning:

Performance Check: Your pipette is tested against the manufacturer's specifications.
Certification: Each pipette receives a Certification of Calibration, indicating a pass or
fail status.
Calibration Date Sticker: A sticker is applied to show the next calibration due date.
This service ensures you have a clear understanding of your pipettes condition before any further action is taken.

How often should pipettes be calibrated?
Most laboratories calibrate pipettes every 3 to 6 months, though high-precision work, GLP compliance, or critical applications may require more frequent checks. The ISO 8655 standard recommends calibration at least once a year, with shorter intervals for pipettes in heavy daily use. AccuCal can help you establish a calibration schedule that matches your workload and quality requirements.
What is ISO 8655 and why does it matter?
ISO 8655 is the international standard that defines the performance requirements, testing methods, and quality assurance for piston-operated volumetric apparatus, including pipettes. It specifies how accuracy and precision should be measured, what equipment is acceptable, and what tolerances apply for each pipette volume. AccuCal's calibration service follows ISO 8655 methodology, ensuring your results are technically reliable and audit-ready.
What does AccuCal's pipette calibration include?
Each pipette receives a multi-point gravimetric test at the required volumes, performed on calibrated analytical balances in a temperature and humidity controlled environment. Calibration can be carried out at your laboratory (most customers prefer onsite) or by post. Tests are performed against manufacturer specifications, the ISO 8655 standard, or your own customer-defined tolerances — let us know which is required for your application. We measure both accuracy and precision and issue a detailed calibration certificate. Minor adjustments and seal replacements can be carried out as part of the same service.
Do you offer onsite pipette calibration?
Yes — onsite calibration is what most of our customers choose. Our engineer visits your laboratory with all the equipment needed and calibrates your pipettes on the bench, usually completing the work within a single visit. This avoids downtime, removes the risk of damage in transit, and means your pipettes are calibrated under the conditions they actually work in. Onsite visits are available across the UK and can be scheduled around your workflow.
Which pipette brands do you calibrate?
AccuCal calibrates all major pipette brands and models, including Eppendorf, Gilson, Sartorius, Rainin (Mettler Toledo), Thermo Scientific (Finnpipette), BRAND, Socorex, and Hamilton, plus electronic and multi-channel models. If you have a less common brand, send us a model number and we will confirm we can service it.
Do you provide a calibration certificate?
Yes. Every pipette comes with a full calibration certificate showing the volumes tested, the measured values, the deviation from nominal, the standard deviation, the tolerances applied, the date of calibration, and the next recommended calibration date. Certificates are formatted to satisfy audit requirements and are accepted by most laboratory quality systems.
How much does pipette calibration cost?
Costs depend on the type of pipette (single-channel, multi-channel, electronic), the volumes tested, whether you choose onsite or postal calibration, and whether minor servicing is included. For an accurate quote tailored to your inventory, please use our online quote form or contact us directly. Most quotes are returned within one working day.
What is the difference between calibration and servicing?
Calibration measures your pipette's accuracy and precision against the chosen specification (manufacturer, ISO 8655, or your own tolerances) and produces a certificate confirming its current performance. Servicing replaces worn parts such as seals, O-rings, and pistons to restore performance. AccuCal can do either or both during the same visit. If a calibration shows your pipette is out of spec, we will usually service and re-calibrate as part of the same job to minimise downtime.
