Pharmaceutical Chambers

Pharmaceutical chambers. Darwin Chambers has developed a reputation among pharmaceutical companies for our dependability, the quality of our products, and the high-level customer service we offer. We know how critical accurate and dependable pharmaceutical storage is for companies that transport and study drugs, medical devices, and other related medical products. We offer standard and custom pharmaceutical chambers and rooms to ensure that each of our client's individual needs and expectations can be met.

The USP identifies two main risks in pharmaceutical supply chains:

  1. The product becoming adulterated during transport
  2. Non-compliance with regulations, guidelines, and standards

With Darwin Chambers, you can have peace of mind that you are not liable for either risk. All of our pharmaceutical chambers exceed FDA and ICH guidelines and are capable of cooling redundancy, which guards against an increase in temperature even after multiple failures.

Darwin's FDA/ICH Pharmaceutical Chambers and Rooms

At Darwin, our PH Series of stability chambers has a line of six units that meet and exceed FDA and ICH requirements. We also offer customizable FDA/ICH stability rooms for those clients that need more extensive storage space.

Stability Chambers

Our six pharmaceutical chamber units range in sizes from a bench top model designed to fit on 24" benches or to be stacked with optional racking, to a larger, 3-door stability chamber, and everything in between. The PH series was introduced in 2003 as the first commercially manufactured large capacity Peltier-cooled pharmaceutical stability testing chamber. Since then, we've continued to innovate to bring the best possible product to our clients not only in the pharmaceutical industry, but also in cosmetics, nutraceuticals, medical devices, and more.

The advantages of a Darwin reach-in pharmaceutical chamber include:

  • Cooling Redundancy — Each pharmaceutical chamber includes multiple, independent thermoelectric cooling units, allowing the chamber to maintain temperature even if it suffers multiple failures.
  • Simple Serviceability — As there is no refrigeration equipment in our pharmaceutical chambers, expensive and time-consuming refrigeration technicians are not required during servicing. Our thermoelectric-based chambers can be serviced in minutes with basic tools, and our ultrasonic humidifier is non-hazardous and can be removed and reinstalled in less than a minute.
  • Superior Control — With thermoelectric cooling and automatic switching systems from cooling to heating, we provide consistent results with a standard control at the sensor of ±0.2°C and ±0.3%RH.
  • Reduced Energy Loads — Our pharmaceutical chambers utilize less energy and place a lighter load on building cooling systems than our competitors' models. As a result, your chamber can be located in spaces unsuitable for other chambers, and you can potentially save thousands of dollars per year.
  • Proven Controllers — Our preferred controllers for our pharmaceutical chambers are made by Fuji Electric. These controllers are widely proven and have the standard functions of:
    • Autotuning
    • Fuzzy logic
    • PID control
    • Programmable alarms
    • Calibration capability
    • Ramp/Soak
    • Offset capability

    Our pharmaceutical chambers can also support other controllers if you prefer.

  • Services and Warranties — Our standard pharmaceutical chamber warranty includes (subject to change per contract):
    • 2 Years All Parts
    • 1 Year Labor
    • 7 Years Thermoelectric Cooling Unit
    • 3 Years Compressor

    We also offer 24 hour technical support, as well as qualification and preventive maintenance at additional cost.

  • Options Available — If you'd like, we can also add chart recorders, data loggers, dryers, and a full swinging interior glass door for the PH034 model.
  • Quiet Operation —Our pharmaceutical chambers utilize quiet and highly efficient DC fans. Locating these chambers in laboratory workspaces is a viable option.

Controlled Environment FDA/ICH Stability Rooms

Our controlled environment rooms are ideal for a variety of research purposes, including pharmaceutical shelf-life testing, accelerated stability studies, animal health products, nutritional supplements, medical devices, therapeutic pharmaceuticals, packaging materials, and more. All of our FDA/ICH stability rooms are designed based on four main principles:


Quality is reflected in each phase of each project, from the initial quote all the way through the lifespan of your pharmaceutical stability room. Everyone who works on your room will be factory personnel or factory trained, with a deep understanding of the needs of the pharmaceutical industry. All of our controlled environment room control panels are CSA certified.


Where competitors often call out 6 month lead-times we may call out 6 weeks or less. We are always fully stocked with the components needed to build any standard and most customized rooms. All of our temperature systems are pre-charged and tested upon arrival at your facility, for exceptionally fast installation.


We use an effective blend of technologies that have been proven to work over time and recent innovations in order to deliver what we believe to be the highest performing stability rooms on the market. From energy efficiency to nearly unbelievable uniformity and control through our on-site validation services. Some of the technologies we utilize include:

Our typical stability room will produce mapped and validated results of better than ±0.5° C and ±1.0 RH throughout the storage volume of the room. Control at a sensor of ±0.1°C and ±0.3% is normal.


We believe our pricing for controlled environment rooms that exceed performance expectations is truly reasonable. Additionally, when you buy a stability room you are not just paying for the room itself, but for a variety of services including installation, electrical efficiency, lost "down" time, and service costs. Our efficient rooms, expert technicians, and affordable service plans all work to cost you less money overall than other vendors. We also work with North Star Leasing to offer financing options, whether our clients need it for tax benefits, or want to maintain working capital and existing credit lines longer.
