Serving Gaithersburg, MD

Gaithersburg is our home city. The Tra-Cal laboratory sits at 8577 Atlas Drive, minutes from the I-270 corridor and Frederick Avenue (Route 355). The National Institute of Standards and Technology headquarters campus at 100 Bureau Drive, the origin of the traceability chain behind every certificate we issue, is here, alongside a biotechnology cluster that includes AstraZeneca, Novavax, and Emergent BioSolutions. Tra-Cal supports these operations with ANAB-accredited ISO/IEC 17025:2017 calibration of test, measurement, and laboratory equipment.

Because our laboratory is inside the city limits, Gaithersburg customers get direct drop-off, scheduled local pickup and delivery with a typical five-business-day turnaround, and onsite calibration appointments‍ ‍at your facility. Each calibration is traced through NIST and accompanied by an audit-ready certificate supporting AS9100, ISO 13485, ISO 9001, and FDA 21 CFR Part 820.

How Tra-Cal Serves Gaithersburg, MD

In-Lab Calibration:

Send your equipment to our ANAB-accredited ISO/IEC 17025:2017 laboratory with prepaid inbound and return shipping. Calibration is performed in a climate-controlled environment against documented procedures, with traceability through NIST. Standard turnaround is approximately five business days from receipt, and asset records are retained with automated due-date notifications.

Onsite Calibration:

Our metrologists travel to Gaithersburg facilities for fixed assets, large inventories, and instruments that should not be moved. Because the lab is in the same city, onsite appointments are typically easy to schedule, and the calibration is performed in a controlled environment at your site with the same accreditation, NIST traceability, and documentation as in-lab service.
