What Are Stability Chambers?

Different products need different environmental conditions for testing, and it is not feasible to move each product to other climatic conditions. Therefore, stability chambers are ideal because the environmental conditions can be changed according to the product under testing.

Stability Chambers

Construction of Stability Chambers

  • The exterior of the stability chamber is made up of anti-corrosive stainless steel material.
  • Sometimes, the front of these chambers is made of glass for easy viewing of the product without disturbing the inner environmental conditions.
  • The rigid stainless steel structure is neatly joined with bolts and nuts.
  • An insulation layer is present between the exterior and interior of these chambers.
  • The stability chambers are provided with a varying number of steel mesh trays.
  • Temperature and humidity control systems are installed in these chambers.
  • For refrigeration, the stability chambers are equipped with CFC-free compressors.
  • The heating process is done by air heaters present in the chambers.
  • LED lights and other safety features are introduced in the chambers for smooth working.

Working Principle of Stability Chambers

  • The stability chambers work on the principle of relative humidity.
  • Relative humidity means the amount of water present in the air and how long the air can hold that water.
  • Stability chambers work by maintaining a stable temperature and stable relative humidity.
  • If the existing temperature increases, then the amount of water that air can also hold increases, resulting in decreased relative humidity.
  • According to the ICH guidelines, the temperature of the stability chambers should not increase more than 1-2 degrees, and the relative humidity should not deviate more than 5%.
  • The stability chambers have sensors attached for detecting temperature and humidity levels.
  • As the environmental conditions are controlled in these chambers, uniform temperature and humidity conditions are generally maintained.
  • For better uniformity of desired conditions, it is preferred to have horizontal laminar air flow. It assists in keeping air flowing through all the trays loaded with samples.
  • Ports are present for the regular removal of exhaust air.

Types of Stability Chambers

There are four different types of stability chambers according to their applications. These are:

  • Environmental Chambers

    Environmental chambers are used to detect any defect in the product. These testing chambers can simulate various climatic conditions from dry, humid, corrosive, rainy or dusty conditions. These chambers can provide adjustable pressures and boost the effects of the sun.

    Environmental Chambers
  • Temperature-Humidity Chambers

    Temperature-humidity chambers are also known as climatic test chambers, and they are used to simulate the effect that a range of temperature and humidity has on a product. These chambers come in a variety of sizes, from small boxes to room-size. The temperature and humidity ranges of these chambers are 163.4°F (73°C) to 374°F (190°C) and 10 and 98% respectively. These are used for products such as telecommunications equipment or photovoltaic solar panels.

    Temperature-Humidity Chambers
  • Accelerated Testing Chambers

    Accelerated testing chambers are the ones in which a product is stored at elevated stress conditions to increase deterioration rate rapidly. By observing the products at high temperature and humidity conditions for a predetermined time period, researchers can predict its shelf life and expiration date.

    Accelerated Testing Chambers
  • Photostability Chambers

    Photostability chambers are used for light testing of the products. These chambers closely monitor temperature, humidity (optional), and light intensity of various drugs. These chambers use fluorescent tubes for a daylight effect, but the lights automatically switch off when the chamber door is open.

    Photostability Chambers

Applications of Stability Chambers

  • Stability chambers are widely used in research labs.
  • Stability chambers are also used in pharmaceutical companies.
  • Stability chambers are used to test various drugs and determine expiration dates.
  • Stability chambers are also used to test extensive tools and production samples before launching them in markets.

Choosing a Stability Chamber

Choosing the right type of stability chamber is very important to offer the right testing conditions for the product. Therefore, there are certain parameters to consider before obtaining a stability chamber.

  • Temperature Range

    Temperature plays a vital role in stability chambers, so it is important that the chamber offer the required temperature range.

  • Humidity Range

    Another vital element of these chambers is the humidity range. Temperature and humidity range goes hand in hand. Therefore, a good humidity range according to the temperature is essential to consider.

  • Size of Chamber

    The size of the chamber should be according to the client’s needs. There are two sizes of chamber. These are:

    • Reach-in Chambers

      These are small-sized cabinet-like chambers used for a small number of products.

    • Walk-in Chambers

      Walk-in chambers are large, spacious chambers used to store numerous products for testing.

Choosing the Correct Stability Chamber Manufacturer

To ensure the most beneficial outcome when purchasing a stability chamber from a stability chamber manufacturer, it is important to compare several companies using our directory of stability chamber manufacturers. Each stability chamber manufacturer has a business profile page highlighting their areas of experience and capabilities, and a contact form to directly communicate with the manufacturer for more information or request a quote. Review each stability chamber business website using our patented website previewer to quickly learn what each business specializes in. Then, use our simple RFQ form to contact multiple stability chamber companies with the same form.
