ISO/IEC 17025:2017 calibration
Valid through April 30, 2027
Why accurate volume measurement matters
If your pipettes drift out of tolerance, your assay, your dose, or your QC result is at risk. A single uncalibrated pipette can invalidate every measurement made with it — and a pipette program that hasn't been verified to spec in 12 months will not survive an FDA audit.
The cost of a calibration program isn't measured against itself — it's measured against the cost of a recall, a hold, or a deficiency notice.
Allometrics has been performing ISO/IEC 17025 volume and liquid-handling calibration since the standard existed. Our certificates will pass your audits and FDA, USP, and Joint Commission review.
Why Allometrics for volume and liquid-handling calibration
A2LA-accredited under ISO/IEC 17025. Cert 2039.01. Continuous accreditation through every revision of the standard.
Onsite, in your facility. Our field metrologists arrive with traceable balances, evaporation traps, and the gravimetric protocols required by ISO 8655 and USP <31>. We calibrate pipettes, burettes, and dispensers in your QC lab, your compounding pharmacy, your R&D bench — without you shipping anything.
Replace 3–5 vendors with one accredited partner. Calibration, cleanroom certification, biosafety, and viables — all delivered by the same team under one accreditation chain. Allometrics' integrated compliance service team ensures compliance and helps you pass your audits.
50 years of regulated-environment experience. Founded 1976. The team has lived every USP revision, every FDA cGMP guidance update, every Joint Commission standards change.
Audit-ready certificates that pass FDA, USP, and Joint Commission review
Designed to pass FDA, USP, and Joint Commission audits on first review. Every Allometrics volume and liquid-handling calibration produces a signed, A2LA-traceable certificate built to survive inspection. Each certificate includes:
- Equipment ID, serial number, manufacturer, model, customer asset tag
- Date of calibration, technician, next-due date
- Reference standards used, with NIST traceability chain
- Environmental conditions at the time of calibration
- As-found readings and as-left readings at every test point
- Measurement uncertainty per ILAC P14 / GUM
- Pass/fail determination against your specified tolerance
- A2LA accreditation symbol and Cert 2039.01 reference
Certificate format is designed for FDA inspections, USP <797>/<800>/<825> reviews by state pharmacy boards, Joint Commission MM/EC chapter reviews, ISO 9001 audits, and the metrology requirements of every customer QMS we've worked under.

Equipment we calibrate
- Air-displacement pipettes (single-channel) — fixed and variable volume, 0.1 µL to 10 mL
- Multi-channel pipettes — 8, 12, 16-channel for high-throughput labs
- Positive-displacement pipettes — viscous, volatile, or dense liquid handling
- Repeater and electronic pipettes — Eppendorf Repeater, Rainin EDP, Sartorius eLine
- Bottle-top dispensers and burettes — Brand Dispensette, Eppendorf Repeater, glass burettes
- Volumetric flasks — Class A glassware verification by gravimetric method
- Graduated cylinders and pipettors — laboratory volumetric ware
Servicing all major manufacturers — Eppendorf, Gilson, Rainin, Hamilton, Sartorius, VWR, Thermo Scientific, Brand, Mettler — and many others.
Service modes
Onsite field service — best for active facilities. Our field metrologists come to your facility with traceable balances and evaporation traps. We perform gravimetric pipette calibration to ISO 8655 / USP <31> in your lab, in your pharmacy, in your QC area — wherever the pipettes live.
Cal lab shipping, dropoff, and pickup — best for ultra-precision work. For pipettes that need extended environmental stabilization or for full pipette overhaul (seals, pistons, tips), bring or ship to our climate-controlled Webster, TX lab. Standard turnaround is 5 business days; expedite available.
Recurring program enrollment — best for multi-site customers. Most pipettes need annual recertification (high-volume labs more often). Allometrics maintains pickup/return logistics for pipette programs across multi-site customers, with a single managed program calendar — your QA team gets one report covering every site.

Calibration framing for specific environments
If you need volume and liquid-handling calibration for industrial QC labs, refinery process measurement, or trade-certified equipment — see our industrial calibration page for trade-cert considerations, on-demand fail-and-respond service, and refinery hot-work permit logistics.
If you need volume and liquid-handling calibration specifically inside a cGMP-regulated environment — compounding pharmacy, pharmaceutical manufacturing, 503B outsourcing facility, ATMP / cell & gene therapy site — see our cGMP / pharma calibration page for the documentation, USP <1058> equipment qualification level (EQL-1 through EQL-3), IQ/OQ/PQ workflow, and audit-survivable certificate format that pharmaceutical work requires.
