Since 1976, Allometrics has provided ISO 17025 accredited volumetric flask calibration services that quality assurance managers trust when audit season approaches. Our A2LA accreditation and NIST traceable documentation give you the defensible measurement data auditors expect to see.
We use the gravimetric method in our temperature-controlled laboratory to test Type A and Type B volumetric flasks per ISO 8655 standards. Field calibration service is also available for large flask inventories to minimize laboratory downtime. Whether you’re validating analytical procedures in pharmaceutical development, maintaining compliance in chemical manufacturing, or supporting research protocols in clinical laboratories, our calibration services provide the documentation you need with the turnaround time your operations require.
Our detailed certificates clearly communicate traceability, uncertainty values, and conformance status—giving you audit-ready records backed by 50+ years of metrology expertise.

Industries That Rely on Precise Volumetric Measurement
Pharmaceutical and Biotechnology Laboratories Quality control labs use volumetric flasks for preparing standard solutions, diluting samples, and validating analytical methods under FDA 21 CFR Part 211 requirements. [1] Accurate volumetric measurements support drug formulation, stability testing, and release testing protocols where measurement traceability directly impacts audit outcomes and regulatory compliance.
Chemical Manufacturing Process chemistry and analytical labs rely on volumetric flasks for preparing calibration standards, testing raw materials, and validating product specifications. Calibrated volumetric glassware ensures your measurements meet EPA and other documentation standards while supporting batch release decisions. [2]
Clinical and Diagnostic Laboratories Hospital laboratories, reference labs, and diagnostic testing facilities use volumetric flasks in preparing reagents, controls, and calibrators. CAP and CLIA compliance requires measurement traceability for equipment used in patient testing workflows. [3]
Additional Industries We Serve Include:
- Food and Beverage Testing: Nutritional analysis, contaminant testing, and FSMA compliance documentation
- Environmental Testing: Water quality analysis, EPA method validation, and environmental monitoring
- Research and Academic Institutions: Method development, validation studies, and published research requiring data integrity

Our Volumetric Flask Calibration Process
What is Volumetric Flask Calibration?
Volumetric flask calibration verifies the actual volume contained or delivered by your glassware against its nominal capacity marking. Over time, glassware can develop chips, etching, or deposits that affect volume accuracy. The gravimetric method we use measures the mass of water contained in the flask at a known temperature, then calculates the true volume using the density of water at that temperature. Regular calibration confirms your flasks still meet the tolerance specifications required for your analytical methods.
Benefits of Regular Volumetric Flask Calibration
Protects Your Analytical Accuracy Calibrated flasks confirm your sample preparation delivers the precision your methods require. Documented uncertainty values support method validation and prove your measurements are defensible.
Satisfies Regulatory Expectations Auditors expect calibration records for volumetric glassware used in testing. Our NIST traceable certificates provide the traceability documentation that inspections demand.
Prevents Costly Failures Inaccurate volumetric flasks cause good product to fail specs or allow marginal product to pass. The cost of one failed batch or product recall far exceeds your annual glassware calibration investment.
Risks of Neglecting Calibration
Audit Findings: Missing calibration records frequently appear in FDA 483 observations and warning letters.
Invalidated Data: Uncalibrated glassware discovered during audits may require investigating historical test results and expensive retesting programs.
Failed Method Validation: Inaccurate volumetric equipment compromises method transfers between sites and proficiency testing performance.
Our ISO 8655 compliant testing verifies your flasks meet tolerance specifications using gravimetric methods in controlled laboratory conditions. Each certificate documents conformance status and measurement uncertainty for your quality records.
