Drug stability test chambers or temperature and humidity chambers (CLIMATE CHAMBER) are important for creating special environmental conditions for pharmaceutical ICH tests. Drug sustainability tests are an important part of the development of pharmaceutical and medical sciences, doubling the chambers’ importance and sensitivity. Stability chambers are mainly used for ICH GUIDELINE Q1A tests, which place the drug in temperature conditions of 40 degrees Celsius and 70% humidity, and measure the stability of the drug in 3-month, 6-month, and even 1-year periods.

The designers of this series of chambers have tried to meet the needs of a wide range of users along with compliance with international standards. For this purpose, facilities such as system DUAL SAFETY (safety thermostat)، Unique HCT technology (Uniformity in different parts of the chamber)، ARM series advanced microcontroller، NON-CUT technology (for accuracy and temperature stability in cooling mode)، ANTIPOLAR technology (to prevent damage to water level sensors) In this series of temperature and humidity chambers are placed. Also, compliance with ICH, GMP, and GLP standards is among the other advantages of these chambers.

The FG design manager assures you that this drug stability test chamber series is fully competitive with European samples, which you will find after reviewing this series of chambers.

In general, environmental condition test chambers or drug test chambers are divided into different types, the smallest volume of which is desktop to the largest volume of which is from about 5000 liters to 25000 liters, and they are called WALK-IN chambers.

As mentioned before, CLIMATE CHAMBERS are part of the important equipment of laboratories and production lines and the quality control department of pharmaceutical factories. But in addition, the chambers are also used in the laboratories of food, health, and cosmetic industries.
However, due to the simultaneous supply of temperature and humidity, they are also used in university laboratories and research and industrial centers. The external body of the chamber is made of iron sheet with electrostatic powder paint, and the inner chamber is entirely made of stainless steel. In addition to its extraordinary strength, it has given the device a special beauty. By carefully looking at the inner compartment of the device and observing different angles, we notice the use of curved corners inside the device, which makes it easy to clean and safe for the user.
Also, using stainless steel makes the inner chamber resistant to humidity. Conversely, the ultra-advanced device controller comes with the latest ARM series microprocessors. The device’s controller significantly contributes to temperature control and stability of temperature and humidity by using smart algorithms.

The temperature and humidity chambers must have a precise temperature and humidity controller, a circulating fan for the uniformity of temperature and humidity inside the chamber, the possibility of warning in case of emergency, the ability to program, the ability to adjust the thermal gradient, the screen to show information, the ability to set the timer. And to be able to save information.

In some cases, it has been observed that the deviation of the temperature and humidity inside the chamber from the set values ​​causes damage to the test samples and sometimes a lot of damage, so the device must be equipped with a separate system to prevent the unwanted increase or decrease of temperature and humidity and to notify It is to the user in case of occurrence.

Another important point of the stability test chamber is the ability to calibrate the device. If the calibration is 1 point, the device is calibrated only at the same point, and by calibrating at one temperature, the calibration of different temperatures is out of adjustment.

Some devices are calibrated in two temperatures; in this case, the device considers a hypothetical line based on these two temperatures and calibrates the rest of the temperatures based on this hypothetical line. Since some points may not be in line with the hypothetical line of the device, calibration at two points cannot be guaranteed for the high accuracy of the device, so the higher the calibration points, the more accurate the calibration is done and the device works in all precise temperature range.

Another point is that you must have encountered the phenomenon of an unwanted increase in chamber temperature and failure of laboratory samples. Today, international standards emphasize the control of the temperature of the chamber by an independent thermostat so that when necessary, by cutting the voltage of the element, they prevent the increase of the temperature of the chamber and prevent possible damage. The ability to connect to FGLAB software is another advantage of this device.

By connecting to this software, you can view all device information, including temperature, humidity, and fan speed, in the form of graphs and tables. Zooming in a specific time range and printing are other advantages of these chambers.

All FG stability chambers have fans and are produced in 4 models of 120, 240, 400, and 700 liters in terms of volume, which, upon request, can also be made according to customer needs. Also, according to the requirements of pharmaceutical factories and the needs of respected customers, it is possible to provide QUALIFICATION documents, including IQ, OQ, and PQ.
