This illuminated growth chamber features dual-program selector dials, which allows control of two temperature conditions and an ON/OFF illumination cycle relative to the program selected. Each system operates independently allowing for simulation of a diurnal cycle, such as an eight hour day cycle of 30°C with light followed by a sixteen hour night cycle of 18°C without light. Forced air circulation ensures the most reproducible test conditions. The chamber air is gently and continuously circulated at a rate that ensures temperature uniformity of all test samples. 4 Supplied shelves.

The unit is equipped with a hermetically-sealed compressor and an independent over temperature safety controller. It also includes a circuit breaker to protect from electrical overload, four fixed shelves, adjustable leveling feet, a condensation drip tray, a steel exterior with welded seams and corners, and a double-coated, baked enamel finish. In addition, one amp interior outlet allows use of shakers, stirrers, roller bottles or other apparatus.
