Climatic Chambers: Definition, Applications, Parameters and more

Posted by ShopLaboratory on 17th Jan 2024

Climatic chambers are an important part of many laboratories, yet there is limited information about them. This article aims to fill the gap in information about laboratory equipment. We are delving into the most relevant topics, starting from the definition of climatic chambers, and continuing with their applications, parameters, that can be controlled in climatic chambers, and the role of humidity in climatic chambers.

Climatic chamber definition

Climatic chambers, also known as environmental chambers or climate chambers, play a pivotal role in various industries, research, and testing environments. These specialized chambers are designed to simulate and control specific climatic conditions, enabling scientists, engineers, and researchers to study the effects of temperature, humidity, and other environmental factors on materials, products, and biological specimens.

Climatic chamber applications

Product Testing and Development

Climatic chambers are extensively used for testing the durability, reliability, and performance of various products under different environmental conditions. This includes electronics, automotive components, pharmaceuticals, and consumer goods.

Biological and Medical Research

In the field of life sciences, climatic chambers provide controlled environments for studying the impact of temperature and humidity on biological samples, cell cultures, and pharmaceutical products. This is crucial for medical research, drug development, and storage of biological specimens.

Material Testing

Industries such as construction, manufacturing, and materials science use climatic chambers to assess how different materials react to varying environmental conditions. This aids in designing materials that can withstand specific climates or environments.

Parameters, that can be controlled in Climatic Chambers


Climatic chambers can replicate a wide range of temperatures, from extreme cold to high heat, to assess how materials and products respond to different thermal conditions.


Some climatic chambers feature humidity control systems, allowing researchers to simulate different humidity levels. This is crucial for testing materials that might be exposed to varying moisture conditions.


Certain applications, especially in aerospace or altitude-related studies, may involve controlling atmospheric pressure within the climatic chamber.


Some chambers are equipped with lighting systems to simulate various daylight conditions. This is particularly useful for studying the impact of specific light spectrums on materials or products.


In specialized chambers, the atmospheric pressure can be adjusted to simulate high-altitude conditions, which is relevant for certain aerospace and high-altitude research.

Gas Composition

For specific studies, climatic chambers can control the composition of gases within the enclosed space to replicate certain atmospheric conditions or study the effects of different gas environments.

Humidity in climatic chambers

Humidity plays a critical role in climatic chambers, influencing the outcomes of experiments and tests. Achieving the desired humidity levels is facilitated by a process known as humidification, which involves introducing water vapor into the air. Various methods are employed for generating humidity in climatic chambers, each tailored to specific applications.

Ultrasonic Humidification

One commonly used method is ultrasonic humidification. Utilizing ultrasonic vibrations, this technology produces a fine mist of water droplets released into the chamber. As the mist evaporates, it effectively increases humidity levels. Chambers equipped with ultrasonic humidifiers offer stability and precision, making them ideal for applications such as seed germination, plant cultivation, and food-related tests. With a maximum temperature capability of 60°C, these chambers ensure a stable and accurate environment.

Steam Humidification

In contrast, steam humidification involves heating water to produce steam, which is then introduced into the climatic chamber. Not emitting ultrasounds, these chambers are particularly suitable for tests involving electronics, plastics, or building materials. They boast an extended temperature and humidity range, creating an environment conducive to the breeding of insects like Drosophila melanogaster.

Lighting in Climatic Chambers

The integration of lighting in climatic chambers expands their capabilities. Growth chambers, specifically designed for plants, seeds, and small organisms, provide not only control over temperature and humidity but also lighting conditions. The phytotron system allows for day and night simulation with smooth regulation of light intensity. Fluorescent tubes strategically placed in door and side walls or mounted as a panel with overhead lighting enable precise control for experiments involving plants, insects, and bacteria.

UV Light Accelerated Aging Test Chamber

For materials testing, especially non-metallic substances like plastics, paints, coatings, and rubbers, UV light accelerated aging test chambers prove invaluable. These chambers simulate, in a matter of days or weeks, the damage that would naturally occur over months or years. Replicating environmental factors such as sunlight, temperature, rain, and dew, this setup assesses color changes and fading in materials. Offering optimal UV sunlight simulation, these chambers provide a controlled testing environment for accelerated conditions, ensuring ease of use and accurate results.

In conclusion...

Climatic chambers have become indispensable tools across various industries, enabling researchers and engineers to understand and address the challenges posed by different environmental conditions. As technology continues to advance, climatic chambers will play a vital role in developing resilient products, conducting critical research, and ensuring the safety and reliability of materials and systems in the face of diverse environmental challenges.
