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 field service — for active facilities and large pipette inventories. We come to you. Full ISO 8655-6 gravimetric calibration in your lab, pharmacy, QC bench, or biosafety cabinet. Pipettes back on the bench the same day.
Webster, TX cal lab — for ultra-precision work, full overhauls, and shipped equipment. Climate-controlled lab. Five-business-day standard turnaround; expedite available for audit deadlines.
Managed multi-site program — for hospital systems, multi-campus pharmacies, and biotech R&D networks. Pickup/return logistics, calibration-due reminders, consolidated certificate package across every site under a single managed program calendar.
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.
