The SI60 and SI60D incubator models by Stuart provide excellent visibility of the samples inside and streamlined access to the working area. These incubators prove useful for a wide range of medical applications to include humidity tests, plant propagation, tropical condition simulation, instrument incubation and corrosion testing. There is also a choice of digital or analog control. The SI60 and SI60D incubator models feature a clear Acrylic® polymer construction to increase visibility of the sample at any given time. These incubator models make it easy to access the front door panel, with each side panel being fitted with 2 x 10mm diameter plugged holes for cable insertion or introduction of gasses. What makes these incubators distinct from other similar products is that they have no base, which makes it easy to place them over complete instruments. However, the base can be had as an optional accessory.
