Growth chambers or germinators are devices designed to create ideal environmental conditions for the growth of seeds or plant eggs. Laboratory germinators provide a controlled environment where light, humidity, and temperature are precisely regulated to ensure optimal conditions for seed or egg development.

Growth chambers are generally categorized into various types, ranging from small desktop models to large walk-in chambers with capacities ranging from 5,000 liters to 25,000 liters.

Key Features of Growth Chambers:

1. Construction and Design:
   • External Body: Made from iron sheets coated with electrostatic powder paint for durability and aesthetic appeal.
   • Internal Chamber: Constructed entirely of stainless steel, providing exceptional strength and resistance to humidity.
   • Curved Corners: The internal chamber features rounded corners, ensuring ease of cleaning and enhanced user safety.
   • Corrosion Resistance: The stainless steel interior is highly resistant to moisture, increasing the chamber’s lifespan.
2. Advanced Controller Technology:
   • Equipped with a state-of-the-art controller featuring the latest ARM series microprocessors.
   • Utilizes smart algorithms to play a crucial role in temperature and humidity stability and control.

These features not only make the growth chambers robust and reliable but also ensure user convenience, precise environmental conditions, and long-term durability, meeting the needs of diverse applications, from small-scale laboratories to industrial-scale research.

Growth chambers are essential equipment for agricultural laboratories. However, beyond this primary application, they are also widely used in laboratories of food, hygiene, cosmetics, and even pharmaceutical industries. Furthermore, due to their ability to simultaneously provide light, temperature, and humidity, they are highly valuable in university laboratories, research centers, and industrial facilities.

Advanced Features in This Series:

The designers of this series of chambers have clearly aimed to meet the needs of a broad range of users while adhering to international standards. To achieve this, the following innovative technologies and features have been incorporated into these germinators:

1. DUAL SAFETY System: Safety thermostat to prevent temperature-related hazards.
2. Unique HCT Technology: Ensures uniform temperature distribution across different points in the chamber.
3. Advanced ARM Series Microcontroller: For precise and efficient operation.
4. NON-CUT Technology: Ensures accuracy and stability of temperature during cooling phases.
5. ANTIPOLAR Technology: Prevents damage to water level sensors for enhanced reliability.
6. HLD Technology: Provides uniform light distribution throughout the chamber.

These features make the growth chambers suitable for diverse applications, offering precision, reliability, and adherence to global standards.

Growth chambers must be equipped with the following features to ensure optimal performance:

1. Precise Temperature and Humidity Controller: For accurate and stable environmental conditions.
2. Circulation Fan: To ensure uniform temperature and humidity distribution inside the chamber.
3. Emergency Alerts: The ability to notify users during critical situations.
4. Programmability: Allows users to set and customize operation schedules.
5. Thermal Gradient Adjustment: Enables gradual temperature changes to meet specific requirements.
6. Display Screen: To show real-time data such as temperature, humidity, and other operational parameters.
7. Timer Setting: For automated operation and time-based adjustments.
8. Adjustable Light Spectrum: Customizable lighting to simulate different conditions, such as cool white, warm white, or growth-specific spectrums.
9. Data Storage: To save environmental data for analysis and compliance with documentation standards.

These features ensure that growth chambers meet the demanding needs of research and development in plant cultivation and other applications.

In some cases, deviations in temperature and humidity within the chamber from the set values have led to damage to test samples and, at times, significant losses. Therefore, the device must be equipped with an independent system to prevent unintended temperature and humidity fluctuations and to alert the user in case of such occurrences.

Key Considerations for Growth Chambers:

1. Calibration Capability:
   • If the calibration is single-point, the device is only calibrated at that specific point. In this case, calibrating at one temperature can cause other temperatures to go out of alignment.
   • Two-point calibration provides slightly better accuracy by assuming a straight line between two calibrated temperatures. However, this method might still lack precision in certain ranges if the points do not align perfectly with the device’s assumptions.
   • The higher the number of calibration points, the more accurate the calibration, ensuring precise performance across the entire temperature range.
2. Independent Safety Systems:
   • The phenomenon of unintended temperature increases within the chamber is a common issue that can lead to sample damage.
   • Modern global standards emphasize the use of an independent thermostat to control the chamber temperature. This safety mechanism cuts off the heating element’s power supply during temperature spikes, preventing potential damage and ensuring reliable operation.

By incorporating these features, FG growth chambers provide enhanced accuracy and safety, making them a dependable choice for sensitive applications.
