Description
The Lafayette Instrument Company model 80391 Sleep Fragmentation Chamber is used to
provide researchers with the necessary tools for sleep fragmentation studies in both mice
and rats. The 80391 maintains an animal environment that is virtually identical to that used in
the original 80390 Chamber. The divider wall has been removed since a much faster sweep
time is now possible. The sweep bar, food hopper, ad lib water and ventilated lid remain the
same. The living environment is now independent of the drive mechanism to reduce noise
and greatly facilitate cleaning. It resembles a standard living environment that includes food
and water support. The cycle time selector includes a variety of different cycle times. The
continuous sweep setting now takes just 7.5 seconds. Selectable inter-sweep cycle values
start at 0.25 minutes (15 seconds) all the way up to 30 minutes. Alternately, sweeps may be
initiated from a remote device.
