A growth chamber or Germinator is a device used to create ideal environmental conditions for the growth of seeds or eggs of a plant; the laboratory germinator provides conditions in which light, humidity, and temperature are controlled. To provide optimal conditions for the growth of a seed.

The growth chambers are generally divided into different types, the smallest volume of which is desktop to the largest volume, which includes about 5000 liters to 25000 liters, and they are called WALK-IN chambers. The outer body of the chamber is made of an iron sheet with electrostatic powder paint, and the inner casing is made entirely of stainless steel; in addition to its extraordinary strength, it has given the device a special beauty. By carefully looking at the inner casing of the device and observing different angles, we notice the use of curved corners, which causes Ease of cleaning and user safety. Also, using stainless steel increases the resistance of the inner chamber. The Growth chamber of the plant is protected against 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.

Growth chambers are important equipment for agricultural laboratories. But in addition, the chambers are used in the laboratories of food, health, cosmetic industries, and even pharmaceuticals. However, due to the simultaneous supply of light, temperature, and humidity, they are also used in university laboratories, research, and industrial centers.

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 a DUAL SAFETY system (safety thermostat), Unique HCT technology (Uniformity in different parts of the chamber)ARM series advanced microcontrollerNON-CUT technology (for accuracy and stability of temperature in cooling mode), ANTIPOLAR technology (to prevent damage to water level sensors) and HLD technology for uniformity of light are placed in this series of germinators.

The growth 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, optical spectrum and the ability to store 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 growth 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. Because some points may not align with the assumed line of the device, calibration in two points cannot guarantee the device’s high accuracy.
Therefore, the more the number of calibration points, the more accurate calibration is performed, and the device works accurately in all temperature ranges. 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.

All growth chambers or FG germinators have fans, and in terms of volume, they are produced in 2 models of 240 and 400 liters, which, upon request, It is also possible to build a plant growth chamber based on the customer’s needs. Also, according to the requirements of plant breeding centers and the needs of respected customers, it is possible to provide QUALIFICATION documents, including IQ, OQ, and PQ.

The ability to connect to the FGLAB software is another part of the advantages of this device. By connecting to this software, you can see all the device information, including temperature, humidity, and fan speed, in the form of graphs and tables. Zooming in a specific time range and printing are also other advantages of these chambers.

All FG growth chambers have fans, and in terms of volume, they are produced in 2 models of 240 and 400 liters, which upon request, can also be manufactured according to customer needs.

Frequently Asked Questions(FAQ)

Considering that the water source of the 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 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.

Body Since many centers do not have facilities such as water or sewage pipes, a feature has been placed in the FG growth chambers so that they can be installed and work properly independently of the deficiencies of the environment. Therefore, the FG germinator is equipped with an inlet and outlet water source. 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 is opened (naturally, the device’s temperature goes higher or lower). In normal devices, the alarm is activated, but in the FG device, the alarm is activated only when needed, and in The malfunctioning device is activated.

No, using HCT technology, moist air enters the device instead of water vapor entering the chamber, preventing the samples from getting wet.

Yes, it can be done by the consumers and according to the request.

In the growth chambers available in the market, light systems are usually placed vertically on the door or side walls of the device, which causes some samples to be placed between the light source and other samples should be placed and other samples should be placed in the shade so that they do not get full light. In HLD technology, light plates are placed horizontally, like floors inside the chamber, and shadows are prevented on the samples.

The FG growth chamber is equipped with the new and exclusive HLD technology, and there is no need to change the lamp and high costs, and you can adjust the light spectrum you want with just a few clicks through the growth chamber board.
