ICH Stability Rooms Without the Long Lead Times

Reduce project timelines and installation complexity with a proven walk-in stability room engineered for regulated environments.

Faster Timelines.
Proven Performance.

The Darwin Chambers pre-engineered walk-in stability rooms are designed to reduce project timelines, simplify installation, and save up to 30% compared to fully custom-engineered solutions. Delivering precise temperature and humidity control that exceeds ICH performance requirements, it’s an ideal solution for regulated environments requiring dependable environmental storage.

Built Around Proven Stability Conditions.

Rather than beginning every project from scratch, these stability rooms have been engineered around one of the most requested ICH stability room configurations.

Demonstrated Environmental Performance

Performance mapping of similar installations, conducted using 24 Type “T” thermocouples and 8 Rotronic HygroClip sensors in conjunction with a Kaye 2000 Validator, has repeatedly documented environmental uniformity better than:

  • ±0.4°C temperature variance
  • ±0.7%RH humidity variance

These measurements were recorded throughout the storage space over a 24-hour period. Documentation demonstrating performance exceeding ICH guidelines is available upon request.


Cold Room Operation & Environmental Performance

The Cold Room Special is designed to deliver precise refrigerated storage conditions for regulated pharmaceutical, laboratory, and research applications.

Chamber Operation

  • Model Number: LAB-G1NN-10X10
