Thermo Fisher Scientific's new environmental chambers for light stability testing, plant growth and insect hatching applications

In line with the regulatory and environmental testing requirements of genomics scientists and researchers, the new environmental chambers from Thermo Fisher Scientific closely and reliably replicate light, temperature and humidity conditions, while offering customization options for use across a wide range of applications.

Equipped with vertical light technology and designed to simulate gradual transitions from day to night, as well as temperature and humidity conditions, the Thermo Scientific 3900 Series Vertical Light Chambers offer a selection of three different modules that have been developed to meet defined application needs, as follows:

• Light stability testing of new drug substances and products, in compliance with the Q1B guideline of the International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH), to ensure light exposure will not result in unacceptable change in properties;
• Plant growth, by simulating sunlight that is high in red and blue radiation, to allow for the study of mutations or for comparing plants grown in different environmental conditions; and
• Insect hatching, to enable mutation research or comparisons between insect generations exposed to different conditions. The cooling coils of the chambers feature special protective coating to eliminate corrosion caused by the excrements of some insects.

The light stays on when opening the door to avoid stress to samples due to sudden changes, while an automatic switch off function is available as an option to protect the operators’ eyes from potentially harmful light intensities, for example, in light testing.

"Establishing ideal light, temperature and humidity conditions is of critical importance to genomics scientists and researchers to ensure they obtain consistent and reproducible test results, while adhering to the most stringent regulatory standards," said Amit Agarwal, vice president and general manager for water and laboratory products at Thermo Fisher Scientific. "In this regard, we have developed the 3900 Series Environmental Chambers to provide our customers with a state of the art, robust product portfolio they can rely on to achieve optimal experimental accuracy and reliability."

For light sensitive applications, such as the incubation of microorganisms, the 3900 Series Environmental Chambers’ stability and reach-in environmental chambers offer a solid door option that prevents samples from being exposed to room light, while also featuring an optional inner glass door for easy viewing of samples without altering interior conditions. The inner glass door has been designed to conform to the DIN12880 standard, which specifies performance requirements and tests for heating cabinets and incubators in laboratories.
