The climatic chamber is a unit capable of constructing stable situations of temperature and relative humidity, to provide controlled climatic states, in order to have a reliable measurement model in the measuring instrument. It is built around a hermetic structure, capable of providing pressures between inside and outside, its main components being an access door, means for humidifying and conditioning the air inside the chamber, sensors and temperature controllers.
In the commercial line, they are considered standard equipment for assessing and measuring the preservation of samples, most of which are used to store pharmaceutical, veterinary, agri-food, biotechnological, biological, chemical, materials and other products, under constant conditions of controlled temperature and humidity.
Camera types
Sometimes, climate chambers can be adjusted with various systems, such as photoperiod, for studies of plants, vegetables, insects, etc., or photostability for pharmaceutical or cosmetic studies. However, taking the pharmaceutical sector as an example, where time studies are very rigorous, climatic chambers are capable of storing products for 12 months in conditions of 25°C +/- 2°C temperature and 60% +/- 5% relative humidity.
Different types of camera are also available, including :
- Constant climate chambers: are used for climatic evaluation, where humidity conditions are precisely regulated at a constant level. In the pharmaceutical industry, climatic zone tests include long-term tests lasting more than 12 months, and accelerated tests lasting more than 6 months. All these tests are used for the authorization and ongoing review of drugs and their principles.
- Variable climate chambers: develop under homogeneous conditions, available to high climatic changes, to satisfy demanding material tests. Determines the lower and upper temperature limit of component failure, the climatic range of operation, conditions of transport, storage and use based on provisions and hidden design flaws. Tests include extreme and rapid temperature and humidity changes to cause accelerated aging to destruction.
Validation of climatic chambers
Climatic chambers are used to maintain specific quality standards, and are indispensable for verifying the behavior of materials in many sectors. They provide a precise basis for the effectiveness of prototypes, under stipulated temperature, humidity and light conditions, which are necessary for the authorization of new products. For camera validation, the following criteria must be taken into account:
- Accurate temperature measurement: Conditions can only be correctly assessed under constant temperature conditions over a long period.
- Light recording and even distribution: for photostability tests, the chamber must be evenly illuminated with a balanced proportion of UVA radiation and natural light.
- Active humidification and dehumidification: for greater flexibility, with or without direct connection to water intakes. In addition, a fast reaction time is important for steam humidification.
- Administration: must have standard human sizes, for better sample handling.
- Accurate calculation and recording: provides reliable results that can be easily analyzed.
