What is a Stability Test Chamber?
Stability test chambers for drugs, or temperature and humidity chambers (CLIMATE CHAMBER), are devices that create specific environmental conditions for pharmaceutical ICH testing, which is very important and essential. Drug stability testing plays a significant role in the development of pharmaceutical and medical sciences, making the importance and sensitivity of these chambers even greater. Stability chambers are primarily used for ICH GUIDELINE Q1A tests, where the drug is placed under conditions of 40°C and 70% humidity to measure its stability over 3-month, 6-month, or even 1-year periods.
The designers of this series of chambers have clearly aimed to meet the needs of a wide range of users while adhering to international standards. Therefore, features such as a DUAL SAFETY system (safety thermostat), unique HCT technology (for uniformity at various points in the chamber), advanced ARM series microcontroller, NON-CUT technology (for precision and stability in cooling mode), and ANTIPOLAR technology (to prevent sensor damage due to water level fluctuations) have been included in this series. Compliance with ICH, GMP, and GLP standards is also one of the advantages of these chambers.
FG design managers assure you that this series of stability test chambers is fully competitive with European models, and you will come to realize this after reviewing the series.
Types of Stability Test Chambers
Generally, environmental test chambers or drug test chambers are categorized into various types, with the smallest models being benchtop versions and the largest models ranging from 5000 liters to 25,000 liters, known as WALK-IN chambers.
Application of Temperature and Humidity Test Chambers
As mentioned earlier, stability chambers are essential equipment in laboratories, production lines, and quality control departments of pharmaceutical factories. In addition to this, they are also used in laboratories of food, hygiene, and cosmetic manufacturing industries. Since these chambers provide both temperature and humidity control, they are also applied in university labs, research centers, and industrial applications.
The outer casing of the chamber is made of electrostatic powder-coated iron sheets, while the inner chamber is entirely made of stainless steel, offering both exceptional strength and a unique aesthetic. Upon examining the interior of the device, one can observe the use of curved corners, which facilitate cleaning and ensure user safety. The use of stainless steel also makes the interior resistant to moisture.
Additionally, the advanced controller of the device, equipped with the latest ARM series microprocessors, significantly contributes to controlling temperature and ensuring temperature and humidity stability.
What Features Should a Temperature and Humidity Test Chamber Have?
Temperature and humidity chambers should have precise temperature and humidity controllers, a circulating fan for uniformity inside the chamber, emergency alert systems, programmability, the ability to set thermal ramps, display screens for information, timer settings, and data storage capabilities.
What to Consider When Purchasing Laboratory Chambers?
In some cases, temperature and humidity deviations within the chamber from the set values have led to the deterioration of test samples and sometimes even significant damages. Therefore, the device should be equipped with a separate system to prevent unwanted fluctuations in temperature and humidity and alert the user in case of an issue.
Another important consideration is the calibration capability of the device. If a device is calibrated at one point, it will only be calibrated at that point, and calibration at one temperature will make other temperatures inaccurate. Some devices are calibrated at two temperatures, and in such cases, the device uses a hypothetical line for other temperatures, which may not be entirely accurate. Therefore, the more calibration points, the more accurate the device’s performance across its entire temperature range.
Another issue is the unwanted increase in chamber temperature and damage to test samples. Modern standards emphasize controlling the chamber’s temperature with an independent thermostat to prevent overheating by disconnecting the heater voltage in case of emergencies.
Additionally, the ability to connect to the FGLAB software is another advantage. By connecting to this software, you can view all device data, such as temperature, humidity, and fan speed, in graphical and tabular form. Features like zooming in on a specific time range and printing data are also benefits of these chambers.

Frequently Asked Questions(FAQ)
Considering that the water source of stability chambers is separate from the device, it is possible to disconnect the source from the device when entering the laboratory and reconnect it after installing the device, in which case the depth of the device without the source will be equal to 75 cm.
According to FG standards and the world’s valid standards, the best distance from the walls, floor and ceiling of the stability test chamber is 10% of the length of the same side, for example, if the width of the device is 40 cm, 10% is 4 cm from each side (left and right). ) and if the depth of the machine is 50 cm, 10% of that means 5 cm from the front and back, the distance from the walls of the machine should be considered for loading.
It always takes time for the internal chamber temperature to reach the set point. The Smart timer is activated when the temperature reaches the set point.
Since many centers do not have facilities such as water or sewage pipes, a feature has been placed in the FG stability chambers so that they can be installed and work properly independently of the deficiencies of the environment. Therefore, the FG stability test chamber is equipped with an inlet water source. And it is an exit and does not need plumbing.
Alarms should be such as to attract the user’s attention. Now imagine a device that repeatedly and unnecessarily alarms, such as when the door of the device is opened (naturally, the temperature of the device goes higher or lower). In normal devices, the alarm is activated, but in the FG device, the alarm is activated only when it is needed and in The malfunctioning device is activated.
No, by using HCT technology, instead of water vapor entering the chamber, moist air enters the device, which prevents the samples from getting wet.
Yes, it can be done if needed by the consumers and according to the request.
Relative humidity has a direct relationship with heat, so there are always restrictions on devices that control both temperatures and humidity. FG devices are no exception, so it is recommended to chart the humidity temperature in the database of the devices FG is referred to.
