With all the positive things that people in the LAS industry have been saying about the Allentown NexGen Mouse IVC, it seems only logical that we would expand the Easy IVC family to include a big brother! The NexGen Rat 900 provides all of the value that you've come to expect from a NexGen IVC, yet tailored to the specific requirements and sizes necessary for today's rat research initiatives. Want to group house large numbers of mice?
The 900's large size is perfect for that as well!


The Montreal Neurological Institute and Hospital is a world-leading destination for brain research and advanced patient care. In September of 2016, Janette Green, Associate Director of the Centre for Neurological Disease Models, and Operations Manager Lisa Volume sat down for an interview with Allentown to discuss their selection of Allentown animal housing solutions for their brand new vivarium.

Smooth and easy sliding in, and the same sliding out...less stress and vibration for your animals and less repetitive motion strain on your staff... those are the benefits of NexGen's innovative plastic runner system. So innovative that the NexGen is changing the way animal care staff perform their wellness checks...they just slide their occupied cages out of their stalls 3/4 of the way and assess their animals. No need to fully remove cages from the rack...making animal observation simpler, easier and faster than ever before!


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!


Lighter, smaller, easier to move and manipulate...that's the NexGen!
Reengineered to be stronger yet lighter, the NexGen uses less stainless steel and a combination of high-quality plastic materials to make the rack
easier to work with. Coupled with easy to assemble cage systems, working with the NexGen is a breeze!
