The Weiss Technik Fitotron® Standard Growth Room (SGR) offers unrivaled accuracy and reliability in the control of temperature, humidity and lighting. State-of-the-art programmer technology and energy efficient lighting systems are used to provide unequalled dependability and durability. This sustainable design offers the end-user a cost-effective solution and durability. This sustainable design offers the end-user a cost-effective solution.


Fitotron® Walk-in’ Standard Growth Rooms permits the researcher to maintain controlled growing conditions of temperature and humidity in a 24hr period with independent selection of photoperiods. A full range of ‘day/night’ cycles with ‘dawn/dusk’ effects can be programmed. Fitotron® Standard Growth Rooms allow the researcher access to most world climatic conditions whilst eliminating the variability found in nature.


SGR’s are available with growth areas from 1.4m2 to 24.5m2 and with lighting up to 500 µmol m-2s-1 plus full humidity control. Alternatively, we can design and build to suit individual requirements.


Weiss Technik is a world leader in the design, build, installation and servicing of controlled environments, environmental test chambers and test rooms. Building on over 40 years experience, our Fitotron® Plant Growth equipment incorporates the latest developments in technology, many having been originated by the company’s own design team. Our proven innovation and design incorporates the very latest advances in state-of-the-art programmer technology and energy efficient lighting systems, culminating in Standard Growth Rooms with a wider performance range, greater control of conditions and with unequalled reliability and durability. Our combination of high quality components, design, and manufacturing expertise enables us to offer outstanding control performance and reassurance of the integrity of the results of temperature, humidity, light and atmospheric testing. Our policy of continual liaison with leading researchers ensures we maintain our premier position as suppliers of high quality plant growth and associated facilities. Weiss Technik provide a range of Fitotron® Standard Growth Rooms. Alternatively, we can design custom-fit solutions for your requirements.
The unique design of the Fitotron SGC 120 Arabidopsis Chamber allows researchers to measure and access small leaves that are tightly bunched together by providing unrestricted access measurements that were previously almost impossible to conduct.

The Weiss Technik pharmaceutical cabinet series is available in four sizes; the Pharma 280, 600, 1300 and 2000 all designed with durability in mind. Theses cabinets have been specifically developed to meet the requirement of testing facilities within the pharmaceutical industry. Also available in stock! click here

The TS-120 test chamber consists of two independently controlled chambers, one that is hot and one that is cold. The temperature shock between hot and cold is achieved thanks to the rapid transfer of the specimens on the lift and the subsequent exposure to a wide range of temperatures.


The TS-60 test chamber is made of two independently controlled chambers. One chamber is hot and the other one is cold. The temperature shock between hot and cold is created with the rapid transfer of the specimens on the lift and the subsequent exposure to a wide range of temperatures.

The pre-fabricated Walk-In/Drive-In test chamber's modular construction facilitates ease of move-in and setup. The WP Series accepts all sizes of roll-up conditioning modules. WP Series is suited for many Telcordia (Bellcore) applications. The WP Series has temperatures up to 150 C (302 F) available providing greater testing options.

This robust temperature and climate test chamber raises the industry standard to ease operation, performance, and reliability. With a patented climate and temperature conditioning system you can create more productive and easily replicated tests for a larger number of products.

With the WTL and WKL chambers of Weiss reproducible climate and temperature tests can be performed directly at your work area. This test chamber was specifically developed for usage in labs with compact dimensions and considerable intrinsic values.
The integral welded floors provide proper drainage of water/fluids. The unit's one-piece custom construction makes the chambers very easy to install. Larger units can be constructed on site.
