ExactPro provides on‑site pipette and balance calibration using ISO‑aligned methods, NIST‑traceable standards, and clear documentation that fits real laboratory workflows.
Every visit includes preventive maintenance, functional checks, and adjustments when possible. Our focus is accuracy, reliability, and transparency — not upselling or unnecessary service.
We support a wide range of laboratory environments by delivering calibration data you can trust and documentation that stands up to internal review and quality expectations. If your workflow requires accredited calibration, we’ll let you know before service.
Single‑channel, multichannel, and adjustable‑spacing pipettes calibrated using ISO‑aligned gravimetric methods. Documentation is available at four levels (B, R, F, X) depending on your needs.
Calibration for precision, analytical, and semi‑micro balances using traceable reference weights. Certificates include environmental conditions, tolerances, and pass/fail status.
Choose the depth your lab needs — from Basic mechanical service (Level B) to full As‑Found/As‑Returned data (Level F), or extended multi‑point analysis (Level X). All certificates are NIST‑traceable and formatted for clarity.
Your equipment stays in your lab — reducing downtime, shipping risk, and scheduling disruptions.
Routine seals and O‑rings are replaced at no extra cost when needed. Most issues are corrected on the spot.
We work around your lab’s schedule — teaching, research, production prep, or general operations.
Use the calculator below to estimate your on‑site calibration cost. Pricing reflects the actual work performed — calibration, preventive maintenance, and documentation — without add‑ons you don’t need.
Pricing is based on instrument type, calibration depth, and total quantity.
How is pricing calculated?
Pricing is based on instrument type, calibration depth, and total quantity. Volume discounts apply automatically at 30+ and 60+ units.
What’s included in calibration?
Every pipette receives mechanical service, seal lubrication, and leak testing. Higher tiers include NIST‑traceable data reports.
Specialized Documentation
From standard verification to full As‑Found/As‑Left tracking, we provide the data depth required for your specific audit environment.
Pricing is based on readability class and total quantity.
How is pricing calculated?
Pricing is based on readability class and total quantity. A NIST‑Traceable Certificate can be added per balance when documentation is required.
What’s included in calibration?
Every balance receives on‑site calibration using NIST‑traceable reference weights, environmental checks, and ISO‑aligned procedures.
Documentation Options
Choose between verification‑only service or a full NIST‑Traceable Certificate. Certificates include tolerances, pass/fail status, and environmental conditions.
Scheduling & Logistics
Travel is included when combined with pipette calibration. If you’re unsure which readability class to select, choose the closest match — we’ll confirm all details before your visit.
I provide on‑site pipette and balance calibration throughout Ohio, Kentucky, and Indiana, including Cincinnati, Dayton, Columbus, Cleveland, Toledo, Lexington, Louisville, Northern Kentucky, Indianapolis, Bloomington, Muncie, and surrounding areas.
I calibrate most major brands, including Rainin (LTS, XLS, Classic), Gilson Pipetman, Eppendorf, Thermo, Sartorius, Labnet, VWR/Accupet, and others. If your model isn’t listed, I can still help — most follow similar calibration principles.
Yes — 8‑channel, 12‑channel, and adjustable‑spacing multichannel pipettes are all supported. Each channel is tested individually, and results are documented according to the service level you choose.
Most labs calibrate every 6–12 months, depending on usage, SOPs, and audit requirements. High‑use pipettes, multichannels, and Rainin LTS/XLS models often benefit from more frequent checks.
Documentation depth is determined by your selected service level to ensure compliance with your lab's quality standards:
Level B: Basic Calibration
• No formal certificate or data report. Includes a service sticker indicating mechanical maintenance and leak testing were performed.
Level R: Verified Calibration
• NIST-traceable Certificate of Calibration including As-Returned data (2 volumes × 4 readings per volume).
Level F: Full Data Calibration
• Comprehensive NIST-traceable Certificate featuring both As-Found and As-Returned data (2 volumes × 4 readings per volume). Critical for audit trails and impact assessments.
Level X: Extended Data Calibration
• Our highest precision report. Includes a 3-volume × 10-reading (60-weighing) analysis for both As-Found and As-Returned states. Features linearity and uncertainty data for master/reference instruments.
Standard on all Certificates:
All certificates include specific test volumes, pass/fail status against manufacturer specs, recorded environmental conditions (Temperature, Humidity, Pressure), unique Certificate ID, and technician signature.
Yes — data availability is determined by the service level selected:
If you’re unsure which level fits your workflow or audit needs, I’m happy to help you choose the appropriate depth.
Yes — when it’s part of normal preventive maintenance for that model. Included at no extra cost (when needed):
These models use simple, field‑serviceable seals that can be replaced onsite.
Additional cost for certain models:
Some pipettes use proprietary or complex internal parts.
For those models, replacement is considered a repair, not routine maintenance,
and may have an additional cost.
If that ever applies, I’ll let you know before doing anything so there are no surprises.
Common causes include:
Most failures are correctable with maintenance.
I’ll identify the cause, perform adjustments or maintenance when possible, and retest it. If a repair or part replacement is needed beyond normal maintenance, I’ll explain the issue and your options before doing anything.
Yes — the methods and documentation in Levels R, F, and X are NIST-traceable and suitable for GLP/GMP workflows. I am not an ISO‑accredited provider, which keeps the service efficient and cost‑effective for labs that don’t require that specific accreditation layer.
No — I follow ISO‑aligned procedures and use traceable standards, but I do not operate as an ISO 17025‑accredited lab. Most higher‑education and research labs do not require accreditation, and avoiding it keeps service straightforward, affordable, and focused on real technician‑level calibration rather than administrative overhead.
Yes — Level X: Extended Data Calibration is designed for labs that need multi‑point verification. This includes a 3-volume linearity check with 10 replicates per volume (As-Found and As-Returned), providing a highest-precision 60-weighing analysis. I’m always upfront if your specific audit or SOP requires an accredited provider instead.
Absolutely. If you ever have questions about tolerances, failure causes, or how to interpret your data, I’m happy to walk you through it in plain language.
Common signs include:
If something feels “off,” it’s worth checking.
ExactPro provides technician‑level, on‑site calibration designed for academic and research labs that need accuracy, clarity, and documentation that stands up to internal review or external audit.
