Humidity chamber for laboratory research and stability testing
A humidity chamber precisely controls temperature, humidity and optionally CO2 for diverse applications. As a result, the unit creates a stable and reproducible environment for stability testing, plant growth, cell culture and controlled storage. This keeps your protocols reproducible and your results reliable. Our humidity chambers from Thermo Scientific cover the full spectrum, from compact units to free-standing systems up to 750 litres.
Which types of humidity chamber do we supply?
Our range covers four main types, each suited to specific applications.
Stability chamber for ICH stability testing: a humidity chamber specifically designed for pharmaceutical stability testing in accordance with ICH Q1A guidelines. As a result, the unit realises exact ICH conditions (25°C/60% RH, 30°C/65% RH, 40°C/75% RH and others). Therefore, you meet GMP and regulatory requirements. Essential for pharmaceutical development and quality control.
Plant growth chamber: a climate chamber with adjustable light for plant growth experiments. Moreover, this configuration offers adjustable light intensity, photoperiod and light spectrum. Suitable for plant tissue culture, germination experiments and research on growth conditions under controlled light and climate.
General climate chamber with temperature and humidity: a versatile environmental chamber for cell culture, microbiological incubation, controlled storage and shelf-life testing. As a result, it is deployable for diverse routine applications where stable climate conditions are essential.
Humidity chamber with CO2 control: a temperature humidity chamber that also regulates CO2 (0 to 20%). Particularly suitable for cell culture requiring physiological CO2 levels. Combines climate chamber functionality with CO2 incubator capabilities.
Key technical features
Temperature, humidity and CO2 control: a humidity chamber from Thermo Scientific regulates temperature from 0°C to 70°C, humidity from 10 to 90% RH and optionally CO2 from 0 to 20%. Therefore, the unit covers a wide range of applications with a single setup.
Peltier technology and active humidification: Peltier cooling provides stable temperature control without harmful refrigerants. Moreover, active humidification offers accurate humidity control with minimal energy consumption. As a result, you combine accuracy with low operational costs.
21 CFR Part 11 data logging: built-in data logging in accordance with 21 CFR Part 11 via USB, Ethernet or Thermo Cloud. Therefore, you meet FDA requirements for electronic records and electronic signatures. Essential for GMP and regulated environments.
Safety and alarm systems: door and temperature alarms, optional door locking, programmable cycles and automatic alarm logging. In addition, internal sensors provide direct measurement and reliable process registration.
Stainless steel chamber and doors: smooth stainless steel chamber with rounded corners for easy cleaning and contamination prevention. Moreover, you can choose between solid or glass doors for visual inspection without opening the chamber.
Touchscreen and internal outlets: intuitive touchscreen operation with programmable cycles. In addition, internal outlets and access ports for external sensors offer maximum flexibility for complex protocols.
ICH stability testing with Thermo Scientific
For pharmaceutical stability testing in accordance with ICH Q1A, Poly Temp supplies stability chambers that realise the standard ICH conditions exactly. These include:
- Long-term testing: 25°C ± 2°C / 60% RH ± 5% RH

Frequently asked questions about humidity chambers
What is a humidity chamber?
A humidity chamber is a laboratory device that precisely controls temperature, humidity and optionally CO2. As a result, it creates a stable and reproducible environment for stability testing, plant growth, cell culture and controlled storage. A humidity chamber is essential for pharmaceutical, microbiological and plant research.
What is the difference between a humidity chamber and a stability chamber?
The terms are often used interchangeably. A stability chamber is a specific configuration of a humidity chamber that realises the exact ICH conditions (25°C/60% RH, 30°C/65% RH, 40°C/75% RH) for pharmaceutical stability testing. Therefore, every stability chamber is a humidity chamber, but not every humidity chamber meets ICH requirements.
What is ICH stability testing?
ICH stability testing is a set of standardised tests that assess the stability of pharmaceutical products under various climate conditions. As a result, you follow ICH Q1A guidelines, with conditions such as 25°C/60% RH for long-term and 40°C/75% RH for accelerated testing. Therefore, you demonstrate that a product maintains its quality throughout the shelf-life period.
What is a plant growth chamber?
A plant growth chamber is a climate chamber with adjustable light for plant growth experiments. As a result, the unit controls temperature, humidity, light intensity and photoperiod. This simulates different climates and seasons for research on plant growth, germination and plant tissue culture.
What is the difference between a humidity chamber and a CO2 incubator?
A humidity chamber controls temperature and humidity, with optional CO2. By contrast, a CO2 incubator primarily controls temperature, CO2 and humidity for cell culture. Therefore, humidity chambers are broader (stability, plants, storage) while CO2 incubators specialise in mammalian cell culture.
How does active humidification work?
Active humidification uses a controlled water system that maintains humidity at the set point. As a result, a sensor continuously measures the RH value and the unit adjusts humidification directly. This keeps humidity within ±5% RH of the set point, essential for ICH stability testing.
What is 21 CFR Part 11 data logging?
21 CFR Part 11 is an FDA regulation for electronic records and electronic signatures. As a result, the regulation requires traceable, tamper-evident data logging of temperature, humidity and other parameters. Humidity chambers with 21 CFR Part 11 functionality meet these requirements, essential for GMP and regulatory submissions.
What temperature and humidity range do your humidity chambers offer?
Our humidity chambers typically operate from 0°C to 70°C for temperature and 10 to 90% RH for humidity. Moreover, optional CO2 control from 0 to 20% is available. Exact specifications depend on the model and the desired application.
Which humidity chamber brands does Poly Temp supply?
We are the official dealer of Thermo Scientific for the complete humidity chamber range, including stability chambers, plant growth chambers and general climate chambers. Moreover, we provide maintenance and service on humidity chambers from all other brands, including Memmert, Binder and Weiss.
How often should a humidity chamber be serviced and validated?
Annual preventive maintenance is the standard for humidity chambers. This includes temperature and humidity calibration, sensor validation, alarm check and NEN 3140 electrical inspection. For ICH stability testing or GMP environments, semi-annual maintenance is recommended, plus IQ/OQ qualification at commissioning.
Can Poly Temp service a humidity chamber from another brand?
Yes. Our certified service engineers perform maintenance, calibration and validation on humidity chambers from all brands. This includes Memmert, Binder and Weiss. Contact us for a tailored maintenance contract.
