Shaker incubator is used for agitation of solutions that need orbital rotation in a temperature-controlled environment. This type of agitation is suitable for microbial medium since the cells are nor under intensive shear stress. In cases where impellers are not usable for stirring, shaker is an appropriate alternative. This unit comprises 25 clamps of 250 ml flasks that can be replaced by larger clamps for flasks up to 1 L. Forced circulation of air is provided inside shaker for temperature consistency and the temperature can be adjusted from room temperature up to 60 C. Shaking speed is adjustable from zero to 250 rpm. The control panel indicates temperature and shaking speed of the unit.
