Is Prism's balance calibration NABL accredited?

Yes. Prism holds NABL accreditation CC-2480 under ISO/IEC 17025:2017. Balance and pipette calibration accepted for GMP, GLP, FSSAI, ISO 9001 audits.

What is ISO 8655 pipette calibration?

Gravimetric method per ISO 8655 — pipette accuracy measured by weighing dispensed water at 10%, 50%, 100% volume using an analytical balance and thermometer. Required for GMP/GLP labs.

How often should a Pipette be calibrated?

ISO 9001 and ISO/IEC 17025 recommend calibrating a pipette at least once every 12 months. Instruments in critical processes, harsh environments, or subject to regulatory audits (FDA, GPCB) may require calibration every 6 months or as specified by the manufacturer.

Does Prism provide NABL-accredited Pipette calibration?

Yes. Prism Calibration Centre holds NABL accreditation CC-2480 and provides fully traceable pipette calibration with NABL-signed certificates accepted by ISO auditors, FDA, GPCB, CPCB, and customs authorities worldwide.

Can Prism calibrate Pipette onsite at our facility?

Yes. Prism dispatches NABL-certified engineers with portable reference standards to calibrate pipette instruments onsite at your facility in Ahmedabad, Surat, Vadodara, Rajkot, and across Gujarat - with zero instrument removal and zero production downtime.

— WHAT IS PIPETTE CALIBRATION —

What Is Pipette Calibration & Why Does It Matter?

Think of a quality lab that relies on a pipette for daily measurements. If it has drifted even slightly from its true value, every reading becomes unreliable — leading to defective products, failed audits, or safety risks. Regular calibration is the only way to confirm your instrument is telling the truth.

Pipette calibration means comparing its readings against a NABL-traceable certified reference standard at multiple test points, recording the deviations, adjusting where possible, and issuing an NABL certificate — accepted by ISO 9001, IATF 16949, and all quality auditors.

Check

Compare readings against a NABL-traceable reference standard across the full measurement range.

Correct

Adjust or document deviations so your instrument reads within accepted tolerance.

Certify

Issue a NABL-accredited certificate (CC-2480) with full traceability documentation.

— OUR PROCESS —

Calibration Process — Step by Step

Receipt & Temperature Stabilisation

Pipette and ultra-pure water (ISO 3696 Grade 1) stabilised at 20 ± 0.5°C for at least 30 minutes in temperature-controlled calibration room.

Visual Inspection

Pipette inspected for cracks, chips at tip, contamination, and scale legibility. Any defects recorded. Tip diameter and seating checked.

Gravimetric Calibration

Water dispensed into tared weighing vessel on NABL-calibrated analytical balance. Dispensed mass converted to volume using Z-factor (density and surface tension at calibration temperature).

5 Repeat Measurements at Each Volume

At least 5 repeat dispenses at each nominated volume setpoint. Mean volume, standard deviation, and systematic error (bias) computed per ISO 8655 / ISO 4787.

Error vs Tolerance Check

Mean error and repeatability (coefficient of variation, CV%) compared to ISO 648 / ISO 835 / ISO 8655 tolerance limits for the stated class.

NABL Certificate Issue

NABL CC-2480 certificate reporting dispensed volume, bias, repeatability (CV%), expanded uncertainty (k=2), calibration temperature, and ISO 8655 / ISO 648 traceability.

— NON-NABL CALIBRATION —

Non-NABL Pipette Calibration Also Available

For routine maintenance, bulk calibration, or internal QC checks where a full NABL certificate is not mandatory — Prism offers cost-effective non-NABL calibration using the same NABL-traceable reference standards and trained engineers.

All measurements traceable to NABL-accredited references
Same Prism engineers, same lab equipment
Calibration report with readings and deviations provided
Ideal for internal QA, maintenance, or high-volume batches

Traceable References

All non-NABL work uses NABL-certified reference standards — readings are still reliable and defensible.

Faster Turnaround

Without full NABL documentation, instruments return faster — ideal for urgent production schedules.

Cost-Effective

Non-NABL calibration costs less — practical for large batches or routine periodic checks.

Onsite or In-Lab

Available at your facility or at our Vatva lab — same quality, more flexibility.
