Do you need a testing environment you can rely on?

Inconsistent sterility testing results can introduce risk to product release and regulatory review.

 

Nelson Labs’ purpose-built cleanroom suite was designed to provide consistent, reliable results so you can move forward with confidence.

A New Cleanroom Designed for Today's Sterility Expectations

Built for Annex-1 Alignment

The cleanroom was designed to align with Annex 1 to support high-quality testing and efficient throughput for consistent release timelines. With optimized layouts, expanded hood capacity, and next generation equipment, the layout and infrastructure enable testing to scale without compromising quality.

Robust Contamination Control

Unidirectional flow for personnel and materials, restricted access, touchless wave-to-open doors, and passthroughs support controlled movement through the cleanroom and preserve the integrity of the testing environment.

Operational Continuity

Two independent cleanroom wings allow maintenance or requalification to occur without shutting down operations, helping you maintain testing timelines and avoid unnecessary delays year-round.

Visibility and Oversight

Continuous monitoring, integrated viewing windows, enhanced recordings, and an audit-friendly design support real-time oversight and provide the documentation needed for investigations and regulatory review.

Why It Matters Testing in a reliable cleanroom environment can support:

  • Greater consistency in sterility testing results
  • Increased flexibility for scaling programs and timelines
  • Reduced risk of retesting or investigation
  • Stronger regulatory alignment with global expectations
  • Confidence in data supporting product release decisions

Expert Support Behind Every Test

Infrastructure alone isn’t enough to ensure reliable outcomes. Nelson Labs combines this purpose-built environment with experienced microbiologists, established quality systems, and cross-functional expertise. If your team is scaling production, addressing Annex 1 expectations, or preparing for regulatory review, Nelson Labs is ready to support you.
