KNOSYS

KNOSYS Users

KNOSYS is a small privately owned company specializing in rodent behavior test equipment. The company was formed in 1995 to market simple and affordable small animal olfactometer units and, in 1997, the product line was expanded to gustometers and a variety of test chambers for mice. The company's directors include specialists in animal behavior and electronics. We offer simple and relatively inexpensive solutions for conditioning and sensory discrimination studies with rodents.

We do only what we do best: providing reasonably priced and highly reliable test equipment for rats and mice. We have avoided idiosyncratic systems, mazes and other tests that involve extensive handling of experimental animals and those that we feel produce highly variable outcomes or outcomes difficult to interpret.

KNOSYS behavior systems have been installed at commercial and non-profit research institutes and universities in a number of countries. We work closely with individual investigators to insure that behavior systems selected will meet their needs. KNOSYS offers on-site installation and training in the use of our equipment and software routines.
