The 721 Low Temperature Incubator, larger than the 721, has an inner working volume about 180L. Ideal for B.O.D. determinations, plant and insect studies, fermentation studies, bacterial culturing, and also ageing testing due to its large temperature range and capacity to change the environment quickly. The 721L allows controlling and maintaining stable environment from -20°C  to 100°C.

As all the Taiwan Hipoint products, the 721L is made in robust anti-rust material. Gentle, continuous forced-air circulation ensures temperature uniformity (+/-0.3°C at 20°C) and rapid climatic change for ageing test conditions.
The refrigerated incubators also include an independent over temperature safety controller, adjustable shelves in 2.5cm increments and in option an electric plug to allow shakers, stirrers, roller bottles or other apparatus use.
