Bahnson Environmental Specialties is now Environmental Specialties, LLC.

Stability Rooms

Stability chambers and stability rooms are temperature- and humidity-controlled environmental units that provide stable conditions for storage and testing purposes. They are designed for specific loading conditions and provide the precise temperature/humidity control required for testing the long-term, intermediate, or accelerated degradation of a product or its packaging over time.

Our skilled engineers are ready to meet the demands of customers seeking complex, high-quality testing environments, including the stringent stability room guidelines set by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH).

Versatile Stability Room Design

Our stability rooms combine maximum flexibility with advanced reliability features, providing precise control over temperature and relative humidity (RH).

REQUEST QUOTE

  • “Thanks again for the support in getting us to this stage eventually – finding an incubator that meets our temperature spec has been a challenge for us for the last few years and this is a significant milestone for the business. Hopefully we will have more good news to report in the new year.”

    Project Engineer, Major Biotechnology Manufacturer

  • “During a recent external audit, an inspector requested the PM/Cal documents for the stability chambers. It was my pleasure to give him the nicely presented binders. I could tell he was impressed.

    Thanks for the great service you have provided for us over the years.”

    Teresa P, Taste Texture and Health, DSM-Firmenich

  • “Environmental Specialties has always provided me with great service. All the individuals I worked with were knowledgeable about ES products and services.  They were highly skilled. I relied on ES for pm, calibration, qualification, repair, chamber sourcing and consultations. I interacted with a lot of your employees.  The feedback was always spot on. They were always smiling and supportive even in the most difficult situations. ES is a great company with good people.”
