Our burette calibration services go beyond basic testing. We perform complete disassembly, thorough cleaning, leak testing, and parts replacement when needed—ensuring your volumetric and piston burettes deliver accurate, repeatable results.
You might manage calibration schedules for hundreds of instruments. Or you might need emergency service for one critical piece of equipment. Either way, we understand the pressure. You need accurate measurements without stopping your lab work. Our nationwide service delivers detailed certificates of calibration with full traceability documentation that satisfies audit requirements.
We Calibrate a Wide Variety of Burettes
Our ISO 17025 accredited laboratory calibrates the burettes used in analytical testing, quality control, and research applications where precise liquid measurement is required. This includes:
Volumetric Burettes:

- Automatic burettes
- Schellbach burettes
- Micro-burettes
Piston Burettes:
- Digital piston burettes (all capacities)
- Manual piston burettes
- Bottle-top dispensers
We calibrate many types of burettes from major manufacturers including Brand, Hirschmann, Vitlab, Kimax, Pyrex, and Corning, as well as other brands used in laboratory applications.

Industries That Rely on Our Burette Calibration Services
Burettes are essential tools for quality control and quantitative analysis, particularly in titration applications where precise liquid measurement directly impacts product quality and regulatory compliance.
Pharmaceutical Industry Quality control labs use burettes for purity and potency analysis, ensuring the correct concentration of active ingredients in medications. FDA regulations require precision titration when you test drug formulas and release production batches. [1]
Food and Beverage Industry Food and beverage labs use accurate burettes for several tests: measuring pH levels in drinks, analyzing nutrients for labels, and detecting contaminants to keep products safe. [2] These precise measurements support USDA and FDA compliance requirements.
Cosmetics Industry Formulation labs use burettes to ensure safe and appropriate concentration of chemicals in cosmetic products. Precise measurement maintains consistency in composition and quality across makeup production batches.
Chemical Manufacturing Process control and quality assurance laboratories rely on burettes for industrial chemical tests, raw material verification, and product specification testing.
Environmental Testing Water quality laboratories use burettes for alkalinity testing, hardness analysis, and contaminant monitoring in compliance with EPA testing methods. [3]
Academic and Research Labs Chemistry and biology departments use burettes as standard equipment for teaching laboratories, research projects, and experimental procedures requiring volumetric precision.

Since 1976, we’ve built our reputation on technical precision and responsive, personalized service. Our technicians understand the unique challenges facing QA managers in regulated industries—we’re not just calibrating equipment, we’re supporting your compliance programs.
Comprehensive Service Beyond Basic Testing
Unlike calibration providers that only perform measurements, we provide complete burette maintenance: disassembly, cleaning, leak testing, parts replacement, lubrication, and reassembly. Your burettes return ready for immediate use.
Nationwide Service With Consistent Quality
Whether you operate a single lab or manage multiple facilities across the country, you receive the same accredited service quality, detailed documentation, and reliable turnaround times at every location.
What is Burette Calibration and Why Do You Need It?
Burette calibration verifies the accuracy of volume measurements delivered by volumetric and piston burettes used in analytical testing. We use gravimetric testing methods that follow standards like ISO 8655. Here’s how it works: We measure the actual mass of water your burette dispenses at specific volumes. Then we calculate the true volume. Our calculations factor in water density, temperature, and environmental conditions.
When you send us your burettes, our technicians will:
- Disassemble the burette and thoroughly clean all its internal and external parts
- Conduct a leak check
- Polish piston and lubricate parts
- When needed, replace seals, O-rings, and friction rings
- Conduct gravimetric testing on 6-place ISO 17025 accredited balances which are certified prior to use.
- Place a non-smudge, traceable label on all burettes listing calibration date/calibration due time
- Provide full documentation of calibration service
- Deliver Certificate of Calibration
Benefits of Professional Burette Calibration
Regulatory Compliance: For those that need it, ISO 17025 accredited calibration provides the documented evidence required.
Measurement Confidence: NIST traceable results give you defendable data when analytical accuracy is questioned.
Equipment Longevity: Our complete maintenance service—cleaning, lubrication, parts replacement—extends burette life and prevents costly mid-use failures.
Audit Preparedness: Detailed certificates of calibration with full traceability documentation eliminate calibration-related audit findings.
Operational Efficiency: Preventive maintenance during calibration reduces unexpected equipment downtime and emergency repair costs.
Risks of Neglecting Burette Calibration
Failed Audits: Missing calibration records or expired calibration dates trigger immediate audit findings and can halt production.
Invalid Test Results: Uncalibrated burettes produce inaccurate analytical data, potentially leading to bad batch decisions, customer complaints, or regulatory action.
Compliance Violations: Operating with out-of-tolerance or uncalibrated burettes violates FDA, ISO, and other industry-specific requirements. You risk warning letters or even facility shutdown.
Increased Costs: Equipment that fails mid-analysis wastes expensive reagents, delays testing schedules, and requires emergency calibration services at premium rates.
Professional Liability: Inaccurate measurements from neglected calibration can compromise product quality, patient safety, or environmental testing results.
Common Questions About Burette Calibration Services
Our burette calibration process involves using gravimetric testing methods that measure actual volume delivery. Our Allometrics lab technicians will disassemble your burette, clean all internal and external parts, conduct leak checks, polish and lubricate the piston, replace worn seals and O-rings, then perform gravimetric testing on 6-place accredited balances. Each burette receives a traceable label and certificate of calibration with full documentation.
The proper method for cleaning burettes includes disassembling burettes and thoroughly cleaning all internal and external parts during the calibration service. Our technicians conduct a leak check, polish the piston, make needed replacements and conduct gravimetric testing. This comprehensive cleaning prepares your burettes for accurate titration work immediately upon return to your laboratory. Our ISO 17025 accreditation and consistent attention to detail makes Allometrics a preferred partner for laboratories across the United States.
Allometrics provides nationwide burette calibration services for local laboratories throughout the United States.
