Optirat® Plus System
The Optirat® Plus IVC rack system features an exceptionally small footprint and the highest density housing, the highest in the industry. Animals are fully protected in our cages, and odors and allergens are contained.
Our unique carousel design is based on our patented direct exhaust ventilation technology, free from motors, noise, and vibration. This original technology creates a low-stress, non-variable environment, ideal for housing and breeding laboratory rodents such as rats, mice, and other rodents.
Optirat® Plus Laboratory Rodent Cages are among the tallest in the industry and allow rats to perform natural behaviors and postures. The optional mezzanine shelf increases cage capacity and adds cage complexity. The feeder can be mounted at the front or the side for increased visibility. A variety of accessories are available to accommodate various experiments and increase animal welfare. External water bottles or auto-water options are available.
This unique IVC rack is trusted by scientists, veterinarians, managers, and technicians worldwide for its proven ability to optimize research while protecting caretakers and providing an ideal microenvironment for the rats and other rodents.

This spacious rodent cage allows the housing of larger groups and fewer single animals. The wide interior enables additional intra-cage enrichment like shelters and allows rats to express natural behaviors, as well as to stand upright, enhancing well-being. The mezzanine increases floor space and adds complexity to the cage environment.
Optirat Plus System’s unique motor-free carousel design provides the highest and most ergonomic cage density. With it’s extended top it gives cage height the animals require for their reach and stretch behaviour.
Our microenvironments are free of noise, vibration, and ultrasound. Our patented airflow system directs and filters room air through the cages and racks directly into the building’s HVAC exhaust system. This system creates a calm, laminar airflow that provides an environment ideal for housing, experiments, and breeding.
Our pie-shaped cage has been enhancing rodent life since 1997. Results obtained from Animal Care Systems cages are reliable, advantageous, and trouble-free.
Only cage we know of where filtered room air gently enters the front of the cage and exits the rear; taking with it allergens, odours and excess vapor. A dryer cage is a happy cage. Since the rack is hooked up to the room exhaust the cages are kept at a negative pressure to the technician occupants. There is no need for motorized, electrical or electronic devices close to your lab animals.

Halcyon Air Tower Air Delivery System
Halcyon Air is the new name in air handling systems. This ground breaking new product has been engineered and manufactured to meet global guidelines for maintaining a healthy rodent micro-environment within individually ventilated cages (IVC).
It includes supply & exhaust blowers in a single slim cabinet for a small footprint. Built on casters for easy maneuverability, it also features quick and easy access to pre-filters. It was designed to be energy efficient (using as little as 30W) with zero rack vibration to minimize the impact on the animals.
The Halcyon Air Tower has a capacity of up to 320 mouse cages while controlling air changes per hour based on the number of cages and cage type (Ultra-Air, Max 75, Dura Cage, Flex-Air, etc.). The summary screen displays the current cage pressure, air flow, cage type and filter capacity readings of both supply & exhaust. Navigate to the options menu to change airflow or cage style, check your filter status or battery backup settings or additional options.
The Halcyon Air Tower is on the cutting edge of technology with a LED touch-screen display and the Safe Guard wireless remote monitoring system, including text (SMS) notifications sent directly to your mobile device. A web-based application (no download required) allows you to monitor the status of your tower from anywhere using your Internet connected device (desktop, laptop, smartphone, tablet, etc.).
The Halcyon Air Tower was engineered with an eye on the future needs of your facility. Simple firmware updates (via USB) will allow for upgrades and new development such as wireless control of multiple towers from the Safe Guard Wireless Monitoring System.
