Humidity test chambers

BINDER humidity chambers stand out when testing material behaviors under constant temperature and humidity conditions.

A humidity test chamber of the KBF P and KBF LQC Series also offers ICH-compliant illumination for standard-compliant long-term tests. In combination with the innovative Light Quantum Control (LQC), they offer a complete reliable solution for photostability testing in one chamber.

Wide temperature and humidity ranges can be achieved with KMF Series chambers—ideal for complex stress tests at, for instance, 85 °C and 85 % RH.

BINDER Humidity test chambers with high temperature accuracy

BINDER Humidity test chambers don't fail to impress with their innovative technology and durable, robust quality. They are incredibly user-friendly and can even be cleaned with ease. BINDER has developed a range of series to address different requirements and fields of application. These climate chambers provide homogeneous light distribution, operating under constant temperature and humidity conditions.
In all BINDER Humidity test chambers, the patented APT.line™ preheating chamber technology ensures perfect temperature accuracy in terms of space and time, even when chambers are fully loaded and used for extended periods of time.
In its KBF series, BINDER offers climate chambers with an expanded temperature and humidity range, allowing for stability tests to be performed with unwavering reliability. Plus, the KBF P series comes with an ICH-compliant light source, making these Humidity test chambers ideal for photostability tests and ensuring clear test results in accordance with ICH Guideline Q1B. There are also illumination cassettes providing flexible placement, so homogeneous light distribution is guaranteed in the interior.



Innovative Humidity test chambers with light dose control

In the BINDER KBF LQC series, an ICH-compliant light source is combined with the option of light dose control, with UV-A and visible light being controlled using ball-type sensors. Once the desired light dose has been achieved, the climate chamber switches off automatically. The KMF series from BINDER has been designed specifically with stress test series in mind. The Humidity test chambers developed as part of this series provide absolutely constant test conditions across the entire usable space. In addition to this, they have a wide temperature and humidity range, are flexible regarding the water supply, and require only minimal space.
BINDER Humidity test chambers stand out when testing material behavior under constant temperature and humidity conditions in all fields, including industry, science, quality assurance, and research.  


Ever ask yourself the question: What is the difference between a humidity test chamber and a environmental simulation chamber? The reality is these two terms are often utilized to describe the same type of testing chambers. Certain industries have adopted the term humidity test chamber while other more industrial focused markets have adopted the term environmental simulation chamber or the shorten version environmental chamber(s).


The more important take away is understanding what a humidity test/environmental test chamber does to control the temperature and humidity inside the chambers within the user operating range. What users do not want is to set the temperature and humidity range to then have high environmental conditions. Heat is generated through gravity convection or forced convection with the use of a fan to provide homogeneous air flow. While humidity can be generated using sterile clean water source that is heated to produce steam which results in humidity. What most people miss is climate inside the chamber is primary dependent on the precision of the temperature control in order to create the right humidity concentration range. The condition which a sample is tested depends on this interdependent balance between temperature-humidity. Built-in the BINDER environmental testings chamber is a continual feedback loop which maintains this interdependent balance to create the simulation that people look for in test chambers. Whether the test chambers is called an humidity test chamber or an environmental chamber depends more on the term used within the industry market space.




When purchasing a humidity test chamber in the pharmaceutical industry, there are six things to consider!

Due to have multiple environmental factors: Temperature, Relative Humidity, and Light performing maintenance is vital to performing stability testing. Each factor needs to calibrate separately often at different temperature points, humidity concentrations, and light intensities. This is frequently accomplish with a trained technician on-site or 3rd party maintenance service provider. For temperature precision the BINDER test chambers have the capability to have temperature mapping perform at 1, 3, 9, and even 27 points. For Light maintenance users need to consider how the light is distributed within the test chamber, the intensity of the light at the different points within the test chambers, and most importantly the type of light. For example, the day light which we all encounter everyday is a combination of Ultraviolet and Visible light.


This means if a person is attempting to perform stability testing which mimics day light closest then the light source being utilized needs to distribute both UV-A and Day light. If either of these two type of lighting is missing then the stability testing will be not as accurate. The climate chamber needs to mimic as close as possible the environment. In other cases the testing chamber needs to comply with an industry standard which is why having the maintenance performed annually is recommend by most manufacturers.
