Optirat® GenII

The Optirat GenII caging system is built on the same structural frame as Optimice and employs the same motor­-free, exhaust-ventilated technology as all Animal Care Systems caging systems.

Optirat GenII cages are large enough to comfortably accommodate rats and other species and provide superior visibility, thanks to the wide front face. Each Optirat GenII rack contains 42 cages, arrayed in seven levels with six cages per level. Each cage is equipped with two 400-mL water bottles and a 1.1-­liter (1.2 quarts) stainless steel feeder.

Optirat GenII cages are available in the same three plastic options as all standard Animal Care Systems cages, amber polysulfone, smoke polysulfone, and clear polycarbonate. Like our other carousel-style racks, Optirat GenII can be positioned against a wall or next to another rack. The rotating carousel provides easy cage access without moving racks or forming large aisles. Rotate the carousel to bring the cages to you.
