Analytical Testing

Deliver confidence in product quality with robust analytical testing integrated
across development, manufacturing, and release

Integrated analytical insight to support
quality, consistency, and compliance

Robust analytical testing is fundamental to successful biomanufacturing. Nexus Bioworks provides comprehensive analytical methods to support raw material qualification, in‑process monitoring, and final product release, ensuring critical quality attributes are verified at every stage of your program.

Operating from FDA-registered facilities in the U.S., and under ISO 13485:2016 and ISO 9001:2015 certified quality management systems, our analytical activities are aligned with cGMP requirements and fully integrated into our manufacturing operations.

We develop and execute approved transfer protocols, followed by fully defined testing plans covering raw materials, in‑process controls, and final product release, ensuring transparency and alignment with your quality expectations from day one.

Overview Equipment Key benefits

Analytical expertise across the product lifecycle

Our on‑site analytical laboratories support a wide range of testing requirements, providing end‑to‑end analytical coverage throughout development and commercial manufacturing:

Raw material verification

Incoming materials are tested against predefined specifications to confirm identity, quality, and suitability before use in manufacturing

In‑process testing

Analytical monitoring throughout production supports process control, early issue identification, and informed decision‑making during manufacturing

Final product release

Robust release testing confirms product quality, purity, and compliance with agreed specifications prior to batch release

All analytical methods are transferred into our facility during the Technical Transfer phase of your project, enabling efficient decision‑making, timely product release, and consistent compliance throughout the product lifecycle.

Our analytical infrastructure supports method development, transfer, validation, and routine testing, enabling reliable execution from early‑stage programs through to commercial manufacture.
