The incubator has a double-walled chamber. The inner chamber is made of stainless steel, and the outer body is made of mild steel, duly powder coated. The temperature inside the chamber is controlled by a PID digital temperature indicator with a PT-100 sensor. The temperature range from ambient (+5°C) to 90°C ± 0.5°C is controlled by the P.I.D. controller. The chamber consists of an air circulation fan. The rotator is inbuilt and is provided with racks to hold six bottles (60 mm Dia × 200 mm Depth) at a variable speed of 2 to 20 rpm. The viewing glass window in the door allows inspection of the specimen inside the chamber.

The incubator is designed to operate on a 220V single-phase AC supply (a model with a 110V supply is also available).
