Digital 10 l, 23 l and 56 l incubators are compact and economically priced, yet offer features not typically found in a basic incubator. The housing is all metal, as is the door frame. See-through acrylic door lets you view contents without opening the door. One shelf for 10 l and two shelves for 23 l and 56 l models are included, and can be adjusted in different levels – additional shelves can be purchased to increase storage capacity.
The heating elements in the incubators are incorporated into the bottom and sides of the aluminum chamber. This provides better temperature stability and uniformity than other incubators in it’s class. A grommet hole in the top of the unit can hold a thermometer for accurate temperature setting
