Pipette Calibration

Pipette calibration — gravimetric & NIST-traceable

Accurate liquid handling is the foundation of reliable results. BMCA calibrates single- and multi-channel pipettes gravimetrically, documenting accuracy and precision for CLIA and CAP.

Single-channel and multi-channel — every configuration

We calibrate air-displacement and positive-displacement pipettes across the full range of configurations found on a clinical or research bench, gravimetrically, at multiple volumes, with as-found and as-left data on every certificate.

01

Single-channel

Fixed and variable volume, from sub-microliter to 10 mL. Multi-point verification across the working range.

02

Multi-channel

8-, 12- and 16-channel heads — every channel tested and reported individually, not averaged.

03

Electronic & repeaters

Electronic pipettes, repeaters, and dispensers, including function and dispense-mode verification.

Liquid handling you can defend in an audit

We evaluate accuracy and precision at each test volume using a gravimetric method with environmental correction, then document as-found and as-left performance — the detail CAP assessors look for.

Why it matters

A drifting pipette silently biases every assay it touches. Routine, documented calibration protects result integrity and removes an easy inspection finding.

Pipette calibration — gravimetric & NIST-traceable — common questions

How are pipettes calibrated?
Gravimetrically: we dispense purified water at defined volumes and weigh it on a calibrated analytical balance, correcting for temperature, pressure, and humidity. From repeated measurements we calculate accuracy (systematic error) and precision (coefficient of variation) against ISO 8655–style limits.
How often should pipettes be calibrated?
Many accredited labs calibrate every 3–6 months for heavily used or critical pipettes, and at least annually otherwise. CAP and CLIA expect a defined, followed schedule — we set and track it.
What volumes and channels can you calibrate?
Single- and multi-channel air-displacement pipettes across the common fixed and variable volume ranges. Each channel of a multichannel pipette is evaluated.
Do you provide a certificate for each pipette?
Yes — a NIST-traceable certificate per pipette showing as-found and as-left accuracy and precision at each test volume, plus a dated label.
Can you calibrate on-site?
Yes, in most cases, minimizing disruption. For pipettes needing repair or deep service we advise the best path to get them back in tolerance quickly.
