The NexGen Rat 1800 Tall cage has an optional, hinged hatch in the lid that provides easy and convenient access to the animals.

Quiet Operation

There's so little you'll hear when using a NexGen that it's easier to describe what you won't: no loud hum, no swirling fan, no air noise as it gets sucked into the blower intake... just quiet. Energy efficient ECM motors along with design expertise applied by Allentown airflow experts ensures you'll barely even notice that the blowers are on.

Colony Health Monitoring


Allentown and Charles River Laboratories have partnered together to develop the Exhaust Air Dust collection methodology — or EAD®. Available in two configurations, neither system requires the use of soiled-bedding sentinel animals, but instead captures and samples aggregate exhaust air from IVCs using a patented collection media that attracts dust particles but doesn't load like a filter, or impact airflow.
