has a temperature range of 5° to 70°C.

These incubators occupy less than 8 sq. ft. of floor space. The huge
chamber offers 30 cu. ft. of  working capacity.

The 6 shelves furnished give 5 sq. ft. of space each, and can support 100
lbs.  Shelf height, adjustable on 1/2" centers, can be varied to
accommodate an innumerable variety of laboratory utensils from petri
dishes to carboys.

A duplex electrical outlet is supplied within the chamber to accept
electrical devices such as roller drums, stirrers, and shakers. The outlet is
activated by an "On-Off" switch with accompanying pilot light located on
the control panel.

Model No.
