Stability Chambers are particularly created tools for evaluating goods and figuring out how long they’ll last, such as drugs, electrical parts, industrial materials, etc. They let you adjust variables like temperature and humidity to thoroughly examine a variety of circumstances. varied products require varied testing environments, yet it is logistically impractical to transfer to different locations for various climatic conditions. Stability chambers can help in this situation and make the job easier. Additionally, they are able to detect variations in product quality that can result from varying exposure to the environment.

How stability chamber works?

The concept of a stability chamber is straightforward: by keeping the temperature consistent, you keep the relative humidity stable too. A stability chamber is designed to maintain a constant temperature, which will also stabilize the relative humidity value. The amount of water that air can hold is measured by its “relative humidity“. When the temperature increases outdoors, air can hold a greater amount of water causing a decrease in relative humidity. How the parameters are automatically and simultaneously updated depends on the relative humidity. The ICH guidelines, which state that changes in temperature and humidity in the stability chamber shouldn’t exceed 5% and 2-3 degrees, respectively, must be strictly adhered to.

The outside and inner bodies of the chamber are made of corrosion-resistant stainless steel, and the interior is lined with the suitable insulation. There are various shelves inside the chamber where items that can be removed simply can be kept. In the chamber, sensors are also put to measure the humidity and temperature. The humidity and temperature inside the chamber are consistently maintained because of the controlled airflow. It is advised to use horizontal laminar airflow to increase the constancy of the required conditions. With such a configuration, the shelves will continue to get a consistent flow of air even after being fully stocked with samples. The connected blowers keep the air moving properly. Data transmission and receiving are done via data loggers.

Tips of choosing stability chambers:

Here are some tips to consider when selecting a stability chamber:

  1. Decide the specific environmental conditions (such as temperature, humidity, and illumination) you need to emulate.
  2. Make sure the chamber can fit the quantity and size of samples you intend to test by taking into account its size and capacity.
  3. Check to see if the stability chamber conforms with any regulations that are pertinent to your industry (such as FDA, ICH, or WHO).
  4. Control of Temperature and Humidity: Examine the chamber’s capacity to regulate both. Check if it can precisely reach and retain the desired set points.
  5. To reduce temperature swings, look for a chamber with a quick temperature recovery after door openings.
  6. Examine the homogeneity of the chamber’s temperature and humidity. A chamber with good homogeneity guarantees that all samples are tested under the same conditions.
  7. Lighting Options: Select a chamber with the proper lighting options and controls if your stability testing calls for controlled lighting settings.
  8. Finding a stability chamber with a reliable data logging and monitoring system is important. It should allow for remote monitoring and alarms and offer real-time data on environmental conditions.
  9. Consider the simplicity of loading and accessing samples inside the chamber when evaluating sample access and organization. The placement and retrieval of samples can be made easier by well-designed shelves or racks.
  10. Durability and quality: Pick a stability chamber from a respected company that is known for creating high-quality, long-lasting machinery.
  11. To ensure the chamber can sustain repeated use, look at the construction materials’ quality.
  12. Inquire about the calibration and validation procedures used by the chamber. To guarantee accuracy in a variety of environmental situations, it should be calibrated frequently.
  13. Energy Efficiency: Consider the chamber’s energy-saving options, including insulation, cooling systems, and modes. Operating costs can be decreased using energy-efficient chambers.
  14. Compliance and documentation: To help with regulatory compliance, make sure the manufacturer offers thorough documentation, such as user manuals, maintenance instructions, and validation processes.
  15. Service and assistance: Take into account whether the manufacturer or distributor offers technical assistance, maintenance services, and replacement parts.
  16. Budget: Set a spending limit for your stability chamber purchase and compare various models within that range based on their features and capabilities.
  17. Reviews and references: Ask people who have used the stability chamber you’re thinking about for their opinions. Insights from them can help you make a wise choice.
  18. Review the manufacturer’s warranty and post-purchase assistance programs. In the event of equipment problems, a strong guarantee can offer comfort.
  19. Future Expansion: Think about if you might need to increase your capacity for stability testing in the future. Select a chamber that can be expanded in case your testing requirements change.
